Scientists learn about Earth’s past supercontinent by studying evidence in rocks and minerals. By examining age, composition, magnetic properties, and other characteristics, researchers can piece together evidence to determine how long supercontinents have been around. By using computer modeling and…
Studies have recently suggested that the core of the Earth may have stopped spinning faster than the rest of the planet at some point in the last decade. Located thousands of kilometers below the surface, this inner core could possibly…
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. Summary [02:08]The organic material in…

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…
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…
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…
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? To modern humans, Earth would…
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…
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…
