The outer core of the Earth is similar to a very hot ball of metals, whose temperature is around 4000 oF to 9000oF.
➡️Mantle:
Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. Mantle is mainly made up of semi-molten rock known as magma.
Crust:
➡️The crust is the outer layer where we live. The thickness is around 0-60 km. It’s a solid rock layer divided into two types:
1)Continental crust covers the land and,
