Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...

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 ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

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 ...

Like all terrestrial planets, the Earth's interior is differentiated. This means that its internal structure consists of layers, arranged like the skin of an onion. Peel back one, and you find another ...

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 ...
