GEOLOGY

Detailed explanation-1: -Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Detailed explanation-2: -The solid, outer layer is called the crust. Below the crust lies a layer of very hot, almost solid rock called the mantle. Beneath the mantle lies the core.

Detailed explanation-3: -The lithosphere is the solid, outer part of Earth, including the brittle upper portion of the mantle and the crust.
