The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

The first step toward learning about plate tectonics is to learn about the Earth's interior structure ... that the Earth is made of three main layers: crust, mantle, and core.

These findings may explain why some experimental evidence has been inconsistent with our current models of Earth's structure. The presence of an innermost layer has been suspected before ...
