While we can't see deep into the Earth, geologists have a variety of neat tricks to create a picture of our Earth's layers. Just like a kid's jawbreaker, Earth consists of layers that differ in ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...

When you look at photographs of Earth from space, the planet looks like a blue marble, with patterns of clouds lying on the surface of the marble. It seems as if Earth's atmosphere is incredibly thin, ...

There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity. Our ...

One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that suggests ...
