Below right: A view not drawn to scale to show the Earth's three main layers (crust, mantle, and core) in more detail (see text). Below the crust is the mantle, a dense, hot layer of semi-solid rock …

Earth's interior structure is a complex arrangement of layers that can be divided into three primary chemical divisions: the crust, mantle, and core.
