What Did the Earth Look Like When Dinosaurs Lived?

The ancient forests were full of life, including dinosaurs, insects, reptiles, amphibians, and tiny mammals that scurried through the undergrowth. When a tree was damaged or attacked, it secreted a viscous sticky substance called resin.

What Did the Earth Look Like When Dinosaurs Lived? #Triassic #Dinosaur #Amber

Summary

[02:08]
The organic material in coal turns to coal tar, which traps the remnants of tree resin. The copal then fossilizes into amber, which preserves the creatures entombed within, giving paleontologists a window back in time.

[04:00]
Amber preserves fossil remains, and when you look at some of the specimens, they actually look like they died yesterday. This allows paleontologists to study the finest details of the morphologies of the animals, plants, and microorganisms preserved in amber.

[05:28]
The way we find amber in Australia is a little different to how we find amber around the world. In Australia we find amber in cold deposits, but in the Baltic Sea and the Dominican Republic we find amber eroded out over thousands of years.

[07:03]
Most of the amber that was originally found in Australia was found just on the beaches as float. However, a bunch of researchers from Monash found some amber rich coal in Anglesey.

Can fossils of dinosaurs be found in amber?

[08:05]
We’ve been working on these fossils for a couple of years now, but the coal mine was about to shut down. We got diggers to take out a huge bunch of coal and take it here, but we only got a small amount of amber.

[09:03]
When we first prepare the amber out, we scratch away at the coal surrounding the amber with hand tools to try and get the amber out. We only focus on the big pieces of amber because they’re worth getting out.

[10:01]
In the angular deposit, we get several kinds of amber. We want to get clear amber that is either green or orange that has inclusions in it.

[11:02]
We don’t really know why the green amber has more stuff in it, but we do know that it was a tastier tree.

[12:23]
Once we have a collection of amber from a piece of coal, we paint it with water to clear it up and look for bio inclusions. Sometimes we find something that looks like a mite or nematode.

[13:15]
If we can’t see anything in the amber, we use X-rays to create a 3d model of the amber, and then researchers can look through it and write papers on the bio inclusions that we find.

[13:56]
To look into the amber, we’ve got to clean off all the excess coal, wash it with water, and temporarily remove the distortions with Cedarwood Oil.

[14:41]
When people look through a microscope, they can see details of 100 million year old creatures. They can also see insects and plant remains, and can embed the remains in resin to protect them.

What did the Earth look like during the Jurassic period?

[15:51]
The first time I polished anything, I polished away half of a flyaway, which was a mistake, but we could image the other half.

[16:37]
There we go, a few mites, nematodes, bits of moss, and maybe some fly legs. These are the really small things that we’re talking about, but they’re exciting because they’re 40 to 42 million years old.

[17:16]
My specialties are plants and geology, and I really enjoy working with amber, which is a plant resin. Miners have been mining amber in Northern Myanmar for over 2 000 years, and the amber represents a terrestrial ecosystem that’s about 99 million years old.

[19:42]
So the tree gives us a glimpse into a tropical environment 99 to 100 million years ago. It produced a lot of resin and sometimes something absolutely extraordinary was found.

[20:36]
We’ve found a dinosaur wing in the Burmite, and we’re trying to reconstruct what type of dinosaur it was by studying the feathers and tissue bones.

[21:34]
Within a piece of amber from Myanmar, scientists have found feathers from a dinosaur wingtip. The feathers are similar to modern bird feathers, but lack some distinguishing features that would allow us to determine that the dinosaur is a modern bird.

[22:44]
We want to understand the evolutionary history of feathers by analyzing the feathers of this specimen. This will help us understand how modern environments would react to climate change or other disruptions in evolutionary processes.

[23:31]
They have found specimens with quite vibrant coloration, which suggests that dinosaurs had vibrant colors and creative patterns even 99 million years ago. Through synchrotron scanning, it might be possible to identify the species and determine the species age.

Why are so many fossils in amber?

[24:40]
Paleontology has advanced so much in terms of imaging that we can use several techniques to study fossils, including Leica microscopes, Bk imaging system, micro Ct scanning and advanced synchrotron radiation.

[27:10]
When you’re holding a fossil, you can use advanced chemical techniques to look at the elemental composition of the fossil to see if there’s anything preserved.

[28:06]
Raman spectroscopy is a technique to study molecular bonds in our sample by scattering light on the sample. The scattered radiation has the same energy as the incident beam, plus or minus the energy of the bonds present in our sample.

[29:24]
There’s still something going on with amber fakes, and you can test for fakes by looking at the specimens associated with the piece, and by looking for organic debris in the piece.

[30:26]
Amber has no inclusions, froth, or little bubbles, and fluoresces a brilliant blue in the ultraviolet light. It also melts at 200 to 250 degrees centigrade and is used in varnishes and medicines.

[31:25]
The inclusions in the resin are reconstituted, and the finest trichomes are gone if the resin is reheated.

[31:49]
There are lots of different techniques paleontologists can use to confirm a fossil, but usually a paleontologist with lots of experience can look at a specimen straight away and say okay, this is this is not right or sure you know this looks right to me.

[33:08]
Paleontologists are finding many different types of animals and plants in burmite from Myanmar, which is 100 million years old. These fossils are giving them clues as to what kinds of organisms lived in this ancient tropical forest.

[34:26]
In order to date coal, we look at the surrounding coal, the surrounding coal’s stratigraphic seconds, and then we look for other fossils within the coal, such as insects, plant remains, and pollen. We can use the pollen to narrow down the age of coal.

[36:57]
Paleontologists have found a fossil of two flies mating, which is 42 to 40 million years old, in the Alcoa Mine in Australia. It’s the only fossil ever found in Australia that actually shows sexual population happening or mating.

[38:13]
Paleontologists are trying to learn more about the cretaceous ecosystem in Myanmar from the Amber. It was a tropical environment, with higher Co2 levels and temperatures.

[39:27]
Paleontologists study ancient ecosystems to understand where we came from and how we’ve evolved over time. They focus on deposits that capture all these ancient remains as much as they can.

[40:32]
Amber is very useful to study the terrestrial environments of ancient organisms, and ant fossils in Australia are giving us insight into ant evolution for the first time.

[41:21]
The monomorium ant has lived in Australia for at least 40 million years, and its fossils are preserved in amber. It’s a fascinating thing to see the actual part of the animal that existed a hundred million years ago.

How Big Is the Moon | The Moon’s size compared to Earth

The moon is the brightest object in our night sky. It seems quite large, but only because it is the closest celestial body. The Moon is a little more than one-fourth the size of the Earth (27%), which is much smaller than the size ratios of other satellites to their planets.

Our moon is the fifth largest satellite in the solar system. The Moon has an average radius of 1,737.5 km and a diameter of 3,475 km, less than one-third the diameter of the Earth. The equatorial circumference is 10,917 km. The area is about 38 million square kilometers, which is smaller than the total area of the Asian continent of 44.5 million square kilometers.

“If you imagine that the Earth is the size of a coin, then the Moon can be compared to a coffee bean,” the researchers say.

Earth's Moon is 3.7x smaller than Earth
SIZE COMPARISON – Earth’s Moon.

Mass, density, and gravity

The mass of the Moon is 7.35 × 10^22 kg, about 1.2% of the mass of the Earth. In other words, the Earth weighs 81 times more than the Moon. The density of the Moon is 3.34 g/cm3. It is about 60% of the density of the Earth. The Moon is the second densest satellite in the solar system after the Jupiterian Io, whose similar parameter is 3.53 g/cm3.

The Moon’s gravitational force is only 16.6% of the Earth’s. A man who weighs 45 kg on Earth will weigh only 7.5 kg on the Moon. A person who can jump 3 meters on Earth will be able to jump almost 18 meters on the Moon.

As on most worlds in the solar system, the Moon’s gravity varies depending on its surface characteristics. In 2012, NASA’s GRAIL mission mapped lunar gravity in unprecedented detail.

“When we see a marked change in the gravitational field, we can synchronize that change with surface topography features, such as craters or mountains,” said mission collaborator Maria Zuber of the Massachusetts Institute of Technology in a statement.

Was There a “twin” Earth in Our Solar System?

There is no doubt that Earth is a unique planet since it is the only planet in our solar system that has developed life. But what if it is not the only one out there? What if there is another Earth?

Video: What If Earth Had a “Twin” In Our Solar System?

Does Earth have a sister planet?

Among all the planets in the solar system, our Earth is unique because it is the only planet on which life has evolved. But what if we got a competitor? What if a second Earth appeared out of nowhere, then there would be two different scenarios. The first is the destruction of both planets and the second has an unexpected but rather logical ending.

However, let’s start with the disaster scenario. The second Earth with the same conditions could exist only if it received absolutely the same amount of sunlight as our planet.

The orbit of our Earth is perfect for receiving the required amount of solar heat. If we were a little farther away, the entire surface of our planet would resemble Antarctica, and if the Earth were a little closer to the Sun, we would all be living in a vast desert inhabited by only a few living creatures. So, for the second Earth to be identical to ours, it would have to follow the orbit of our planet.

Two massive objects can exist close to each other?

The union of the Earth and the Moon is a good example, but if the second object were as heavy and large as our planet, there would not be enough room for both. The gravity of two Earths would be a big problem. The two worlds would collide because they would be pulled toward each other.

This process would last hundreds of millions of years, and in the end, the two planets would turn into one huge world. And their remnants would fly around the newly formed planet, much like the rings around Saturn, or one of the planets would push the other out of its orbit. In this case, one of the Earths would hurtle toward the Sun and burn like a match in its atmosphere.

It should also be remembered that the Earth is moving at a speed of 67,000 miles per hour at any given time. That is more than 80 times faster than the speed of sound. Now imagine two giant planets moving toward each other at such a speed.

Even a microscopic organism living in the maw of a volcano would have no chance of surviving the collision of two Earths.

Earth’s twin

Even the moon would be torn to pieces by the blast wave, but let’s imagine that Earth’s twin is orbiting in a different orbit somewhere between Mars and Earth. Even in this situation, people’s lives would be changed forever.

By the way, the theory that Earth could have a twin has been around for a long time. The scientists of the past believed that the second planet could be hiding on the opposite side of the Sun. Thanks to modern technologies and astronomy, we know that this theory is not true. Otherwise, our telescopes and other devices would have already picked up some signals from this planet.

Scientists study space objects thousands of light-years away from us, so they would certainly notice another world nearby.

But be that as it may, let’s assume that the second Earth really exists and that we have discovered it recently. The entire field of astronomy and astrophysics would immediately be funded to the tune of hundreds of billions of dollars. The study of the twin of the Earth will become a priority goal for people. Experts will come up with hundreds of hypotheses about what the second Earth looks like and what is going on on it.

Scientists Discover a Mysterious Structure Hidden Inside the Earth

Scientists uncover a strange structure below the surface of the planet – About 4.5 billion years ago, the Earth formed from a solar nebula. It weighs 5972 yottagrams, and its radius is 6371 kilometers. There is so much information about our planet that it seems that scientists have studied everything about it. Unfortunately, this is an assumption that is far from the truth.

The Earth’s interior contains a mysterious structure.

What is UNDER the Earth’s crust raises more questions than it answers. And to find the answers to those questions, scientists use any method they can get their hands on. What ancient planet could be hidden inside the one we inhabit? How does the earth’s crust sound? How did the deepest journey into the Earth come to a stop?

Mysterious Structure Found Inside Earth

Our Earth consists of three main layers. The first to consider is the crust. This is the outermost layer of the planet. Its depth ranges from 5 to 75 kilometers. The thickest layers of the crust are found on the continents and the thinnest at the bottom of the oceans. The Earth’s crust is made up of plates that constantly move at the same rate as our nails grow.

This movement is due to the mantle, the next layer of the Earth. The depth of the Earth’s mantle is about – 2890 kilometers. This layer consists of silicate rock heated to 900 degrees Celsius near the crust and up to 4000 degrees Celsius at depth. When this glowing substance erupts upward, volcanic eruptions occur.

Finally, the last layer of the planet is the most mysterious. This is the core—the heart of our Earth. The radius of the core is about 2180 kilometers. The inner core is solid and is probably made of iron. The outer one is liquid and is made of an alloy of nickel and iron.

Moreover, the inner core rotates at a different speed than our planet. To explore the secrets of the inner layers of our world, scientists regularly perform various measurements. During one such seismic tomography of our planet, scientists discovered something strange: the mysterious lumps floating in the Earth’s mantle. Some of these clumps join together to form large-scale regions. The two largest are located under Africa and the Pacific Ocean.

How do scientists know what is inside the Earth?

Geological anomaly under Africa and the Pacific Ocean

Rather than floating harmlessly in the Earth’s mantle, they are creating a unique anomaly.

In particular, it is the South African anomaly, which weakens our planet’s magnetic field. Serious changes in the magnetic field can lead to catastrophic consequences, up to and including a change in the polls. The anomaly, however, is not as strong as it could be. So what is the reason for it?

Where did Earth’s water come from?

Origin of water on Earth: Scientists say it probably came from the asteroid belt between Mars and Jupiter. Scientists have long wondered about the origin of the Earth’s water. Until now, the official version was that the volatile elements (such as hydrogen, nitrogen, or carbon), and even the first organic matter, arrived here from the outside, brought by comets and by a class of meteorites of very ancient origin, the carbonaceous chondrites. Both classes of objects formed beyond Jupiter’s orbit and then “migrated” into the Solar System. Now, a new study has just revealed that this was not the case.

Of course, determining exactly where these essential elements came from means being able to understand how water, and life, got to Earth.

Video: History of the Earth – Where Did Earth’s Water Come From?

Water on Earth and its origin

Now, a group of researchers from the Carnegie Institution of Washington has just published an article in Science according to which the water on our planet is not the same as that which was distributed, in the form of ice, throughout the Solar System, but came much later. And not aboard distant comets from the confines of the Solar System, but much closer: from the asteroid belt between Mars and Jupiter.

For Conel Alexander, principal investigator of the study, a large amount of water ice was distributed throughout the early Solar System. However, that ice was never part of the materials that were added to form the Earth. That early ice can be found today in objects such as comets or the aforementioned carbonaceous chondrites. But their analysis shows, according to the researchers, that the two types of objects were not born beyond the orbit of Jupiter, as was believed. Instead, they were born, they were born in two very distant areas. Comets are formed in the outer regions of the Solar System. The carbonaceous chondrites formed much closer.

Alexander established this difference by calculating the proportion of deuterium (an isotope of hydrogen) found in the water ice of 85 carbonaceous chondrites. The farther away from the Sun an object has formed, the more deuterium it contains. And if comets and carbonaceous chondrites formed in the same place, their ice should include the same, or similar, amount of deuterium. But this is not the case.

Deuterium, highlighted from the table of isotopes.
Deuterium – table of isotopes

The ice of the meteorites analyzed contains much less deuterium than comets, suggesting that the latter formed much farther from the Sun. This result also contradicts the most widely accepted models of how the Solar System acquired its current architecture.

For Alexander, the deuterium content of the carbonaceous chondrites indicates that these meteorites must have formed much closer to the Sun than comets. Specifically, in the asteroid belt, the large ring of rocks lies between Mars and Jupiter’s orbits. And that, the study suggests, is precisely where Earth’s water comes from. Alexander is convinced that the results of his research will force the revision of current theories. In addition, they will contribute, in passing, to resolving a variety of questions that have so far resisted science.

Where Did Earth’s Water Come From?

If we stick to what we know, Earth’s water came from comets and asteroids. That’s the most widely accepted theory. But a new study suggests that perhaps not all water reached our planet through this system.

Searching for the Origins of Earth’s Water

Hydrogen is the most abundant element in the universe (after all, it is composed of a single proton and an electron). In the study, a group of researchers suggests that some of this element could come from the solar nebula. That is the cloud of gas and dust in which the Sun formed. If the approach is correct, it could replace the best-known theory about how water arrived on Earth.

It has always been thought that water arrived through the impact of comets and asteroids until now. After the formation of the Sun, the young star expelled most of the material from the cloud in which it was located. When its fusion began, the solar wind sent a lot of hydrogen from its outermost layers into the interior of the solar system. To the vicinity of Mercury, Venus, Earth, Mars, and the outer solar system.

Here, we find the giant planets (Jupiter, Saturn, Uranus, and Neptune) and a multitude of comets and asteroids. As you may know, Comets are frozen, rocky objects that can contain large amounts of hydrogen. Asteroids, although to a lesser extent, may also contain hydrogen. This is because it was a sphere of molten magma when the Earth formed. Its surface was kept in that state by the collision of asteroids.

The cooling process of the Earth

Video: Earth’s Core Cooling Faster Than Scientists Thought

With the Earth in this molten state, the water from the impacts of comets and asteroids evaporated into space. But, over time, our planet cooled down. Earth’s water may have begun to arrive from asteroid and comet collisions. Little by little, the element condensed on the surface, instead of evaporating into space. This scenario is supported by the isotope ratio.

The amount of the isotope of deuterium, compared to normal hydrogen, is a signal. If two objects with water have the same ratio, it is reasonable to assume that their origin must be the same. The Earth’s oceans have the same proportion as the water of the asteroids. All this would seem unappealable, but the approach has always offered some doubts. In 2014, some scientists analyzed meteorites of different ages.

Among them, are carbonaceous chondrites. They are the oldest known meteorites, having formed at about the same time as the Sun. As well as meteorites that may have originated from the asteroid, Vesta. It formed in the same region as Earth, about 14 million years after the formation of our planet. They stand out for having a lot of water. So it is believed that they may be the primary source of water on Earth.

Clues of the formation of the planets

What does this mean, and why does water near the core contain less deuterium? With this model, researchers can calculate how much water comes from asteroid impacts. They also compare how much water comes from the solar nebula. They conclude that for every 100 water molecules on Earth, one or two originate from the solar nebula. The study offers a fascinating perspective on planet formation.

So does its evolution and how life might have arisen on a planet. The model, the researchers say, suggests that water formation is inevitable on any sufficiently large rocky exoplanet. This contradicts earlier conclusions. Earth’s water and its origin could be a very significant clue. According to an earlier hypothesis, the only planets on which life could form would be those with asteroids and comets that contain water.

However, if this model is correct, it would not be necessary. In other star systems, planets could have received enough water from their solar nebulae to have enough water for life to evolve. Most of Earth’s water is found below the surface. There could be up to twice as many oceans in Earth’s mantle as on the surface. It could be up to 4 or 5 times as much near the core.

The model

However, the model is not as robust as we would like. The hydrogen fractionation is not well understood. It is not clear how the ratio of deuterium to hydrogen changes when the element dissolves in iron. This is an essential point because it is an essential part of this new study, and the researchers had to guess what that ratio was.

In any case, the study fits with what was already known about the origin of water on Earth. The great novelty is that it gives a new insight into the possible origin of this water. It is very interesting, both to better understand how it came to be on our planet and to understand what the rocky exoplanets we have discovered might be like. If there need not be water-rich comets and asteroids, the prospects are more promising.

This in no way implies a greater likelihood of finding life. After all, we know that water is a necessary prerequisite. It is an essential building block of life on Earth. But there are other factors to consider—for example, the atmosphere’s composition. But studies like this will, in time, give us a much more complete picture, not only of the solar system but of other places in the galaxy.

The study is J. Wu, S. Desch, L. Schaefer; “Origin of Earth’s Water: Chondritic Inheritance Plus Nebular Ingassing and Storage of Hydrogen in the Core.” Published in Journal of Geophysical Research: Planets on October 9, 2018.

How Did The Earth Look 2 Billion Years Ago?

The earth has undergone a number of dramatic changes over its history and is still doing so today. But what was it like billions of years ago?

What was Earth like 2 billion years ago?

Video: History of Earth

To modern humans, Earth would look like a planet devoid of life. This is because modern cells, which are many thousands of times larger than primitive cells, didn’t evolve into existence until 1.5 billion years ago. Only then could animals and plants start along their evolutionary paths.

Primitive cells similar to modern cyanobacteria and archaea were pretty much everywhere 3.5 billion years ago. Still, you wouldn’t see them because, like today, they were too small. Oxygen in the atmosphere did not exist.

An ice age that lasted hundreds of millions of years ended 2.1 billion years ago. With the global warming that followed, some cells developed abilities to photosynthesize and excrete oxygen. Oxygenation of the atmosphere was well on its way in year 2 billion. Eventually, this oxygen would kill almost all life on Earth. What survived became us.

The largest meteor impact in world history occurred in South Africa, almost exactly 2 billion years ago. However, what impact it had on the weather is not known.

What was the Earth like two billion years ago?

The day was 20 hours long, and the year was 450 days. The moon was 30,000 miles closer to Earth. It would have looked larger than now and had a more substantial effect on ocean tides.


Recommended Post: Why does the Moon look different in different places?


The crust of the Earth was more active than now. As a result, volcanic activity and earthquakes were more common.

The Earth’s magnetic field was half what it is today. The solar wind stripped the atmosphere more effectively, which probably accelerated the turnover of Earth’s atmosphere from anaerobic to aerobic. This was to intensify and accelerate the extinction from toxic oxygen increasing in the atmosphere.

The color of the sky would be bluer and less purple than today due to lower levels of oxygen and higher nitrogen levels. The Earth would have no green plants or any other vegetation to add to the many colors seen everywhere today.


How Many Planets Can You Fit Between the Moon and Earth?

The average distance between Earth and the moon is 384,000 kilometers. The largest planet in our solar system is Jupiter with a diameter of 1,400,000 kilometers, which means that fewer than three of these planets can fit between Earth and the Moon. The truth is that Jupiter is about as big as a planet can be (diametrically speaking).

Depends on the size of the planets

The smallest planet in the solar system is mercury with a diameter of 4900 km, which means that between the Earth and the moon you can fit about 80 of these planets.

But a planet can be even smaller – 1,000 kilometers, if not less. There is such a body in our solar system – Dwarf planet Ceres, but it is located within the asteroid belt and is therefore defined by the new definition (which I think is silly) as a Dwarf planet rather than a true planet, as is Pluto. You can place up to 400 of these planets between the Earth and the Moon.

The answer is between about 2 and 400.

Video: What would it Look like with all the planets between the earth and the moon?

What Are The Diameters of the Planets?

  • Mercury 4,879 kilometers
  • Venus 12,104 kilometers
  • Mars 6,771 kilometers
  • Jupiter 139,822 kilometers
  • Saturn 116,464 kilometers
  • Uranus 50,724 kilometers
  • Neptune 49,244 kilometers

Total: 380,008 kilometers

All the planets of the Solar System fit between the Earth and the Moon, as illustrated in the image you can find here.

How many planets can you fit between the Moon and Earth.

What’s more, there would even be room for Pluto (if it ever regains its status as a planet).

There would also be room for Pluto, since its average diameter is 2,390 kilometers.

Despite the gigantic size of Jupiter and Saturn (alone they occupy more than half the distance) the rocky planets together do not even come close to the diameter of Neptune.

It should also be said that the calculation only works with the mean radius of the planets. With the equatorial radius, we would overshoot by about 3000 kilometers (and with the polar radius we would have even more space left over since, for example, Saturn, has an equatorial diameter of 120,000 kilometers and a polar diameter of 108,000.

Do We Get Any Heat From Other Stars

Heat from other stars. Does the Earth receive heat from the millions of other stars in our galaxy? Does the light bring the heat and perhaps it cools down on the long journey through space to reach the earth and therefore no significant amount of heat arrives here?

While we do receive heat from other stars, the question of whether this heat is quantifiable is debatable.

You can also look at it this way: The Earth would cool to 2.7 Kelvin (270.4°C) if the Sun and stars were magically turned off. Compare that to the pleasantly warm planet we experience thanks to the sun.

Heat from other stars

The stars in our galaxy are extremely close to us in a cosmological sense. Even the Andromeda galaxy is extremely close. The light we see from the stars in our galaxy is roughly equivalent to the light they emit.

At very, very large distances (much, much longer than the distance to Andromeda), the cosmological expansion of space causes the light to be redshifted. The amount of redshifted light gives an indication of the distance to a distant object.

We receive a tiny amount of energy from the cosmic microwave background. This radiation was not emitted by stars. It marks the transition from a very hot and opaque universe to a cooler and more transparent universe. The universe went from opaque to transparent when the temperature dropped below 3000 Kelvin (2726.85°C) or so. Now this light has an effective temperature of only 2725 Kelvin (2451.85°C).

One way that stars can affect our weather is through the influence of cosmic rays on cloud formation. It appears that cosmic rays can trigger high altitude clouds. The effect of those high clouds on the weather is less clear.

Why Don’t We Feel That the Earth Is Spinning?

Clara learned from her older sister that the earth rotates. Always. Who would have to believe that? We would feel it! Wouldn’t we?

Before we delve into the answer to this interesting question, it would probably be exciting to know why the earth rotates in the first place.

Well, it’s a bit complicated, but you could say that when the sun and its planets formed, there was a lot of dust and gas flying through space.

This led to huge dust clouds, which at some point became so dense that they contracted under the influence of gravity.

The components of these dust clouds gradually began to spin and began to rotate.

The Earth developed from one of these dust clouds. And since there was and is nothing in the vacuum of space to stop the rotation, the original spin remains.

Video: Neil deGrasse Tyson Explains the Earth’s Rotation

Just like the other planets, the Earth rotates around the Sun. It takes one year to do so, which is 365 days. But the Earth doesn’t just spin around the Sun, it also spins around itself, like a figure skater doing a pirouette. It also spins quite fast: at the equator with about 1670 km per hour and at our latitudes, i.e. where we live, with about 1000 km per hour. This speed is comparable to that of a passenger plane! By the way, the equator means the place where the earth has its greatest circumference, that is, where it is thickest. It is like putting a belt around the earth.

Why don’t we feel that the earth is rotating

The answer is actually very simple: because everything on Earth is spinning, too. Imagine you are sitting in a car. You notice that the car is moving just because you see the trees, houses, and cows go by. And maybe even because you can hear the engine. In an airplane, on the other hand, you don’t notice that the plane is moving, even though it has a much higher speed than a car. But when you look out the window, there’s often just blue sky and nothing stopping and flying in front of you.

So the rotation of the earth is not only about the land and the mountains and the seas, but also about the birds and the clouds; everything that belongs to the earth because it is attracted to the earth. This is called the gravitational attraction of the earth. The earth’s sphere is in a kind of huge balloon, the earth’s atmosphere. In this balloon is also the air that we have to breathe. And everything in this big balloon is attracted to the earth and does a pirouette together with the earth every day.

The only thing we can see that does not spin with us is the sun. In the morning we see it rise and in the evening it sets on the other side. That’s why we can’t stay in the same place throughout the day. In the garden it may shine in the morning, in the afternoon it may be in the shade. Almost as if the sun is moving. But it doesn’t. The earth moves. We don’t feel it. But we can see it, thanks to the sun.

Earth Day – International Mother Earth Day

Earth Day, officially known as International Mother Earth Day, occurs every year on April 22nd.

The celebration of Mother Nature helps to highlight to the world’s population and governments the dangers facing our ecosystems due to the improper use of their natural resources.

Why is Earth Day celebrated?

Earth Day celebrated. The International Mother Earth Day.
Small actions in favor of the earth will mean a great change in the containment of its deterioration.

International Mother Earth Day was born from the organization of prominent North American environmentalists who could foresee that the massive and uncontrolled exploitation of natural resources would affect the health and lives of all human beings.

Why is Mother Earth-Day celebrated on April 22?

On April 22, 1970, Gaylord Nelson, a Democratic U.S. Senator, along with other groups, organized a mass demonstration to demand the protection and safeguarding of the natural resources that the Earth provides.

Nelson recognized that the U.S. government did not care about the indiscriminate exploitation of resources. Also used the rise of the student movements that had emerged from the convulsive decade of the 1960s to direct his protest at the nation’s universities and study centers.

Gaylord Nelson, who chose April 22 as the date for the protest, and Julian Koening, his collaborator in organizing the demonstrations, gave it the name Earth Day, which quickly became popular.

It was the most opportune time to engage students in discussion about Mother Nature’s environmental problems and, in this way, solidify the urgent debate about possible solutions for them.

Meaning and importance of Mother Earth-Day

According to the United Nations, Earth Day aims to achieve a fair balance between the use of natural resources and the economic and social needs of present and future generations.

Earth Day was created to recognize the urgent need for each and every inhabitant of this planet to address the ecological imbalance we have created through the mismanagement of natural resources.

The celebration of the day of our Pachamama:

  • makes us reflect
  • consider that our small daily choices
  • conservation and reuse of resources.

How can we take care of Mother Earth?

Creation of Earth Day

There are a myriad of options you can undertake from home to help reuse your plastic containers or organic waste.

The use of composts to feed your garden soil or plants is much healthier for our Mother Nature than chemical products.

Plastic shopping bags can be replaced with cloth bags. If you don’t manage to do this, at least try to always use the same bags.

If you have children, the best way to help the Earth is to teach them little things about nature and its conservation. Children lead by example, and if you teach them to conserve water when bathing or brushing their teeth, you’re already making a difference.

Currently, the viral competition #Trashtag Challenge is booming. This includes photographing a public place full of trash, cleaning it up, and then uploading the photo to social media. It’s a way to raise awareness among your friends and acquaintances about how important this is to the health of our beautiful planet.
