Detailed explanation-2: -Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.

Detailed explanation-3: -* The Earth’s crust is the outermost surface. *It is a very thin layer of solid rock. It is the thinnest layer of the Earth. *The crust is 5-35km thick beneath the land and 1-8km thick beneath the oceans.
