Question

what is earth crust?

Answer 1

There a 4 layers of the Earth.

Crust: The thin upper layer of Earth comprised of lower density rocks. It can vary from 5 to 50 km thick.

Mantle: The mantle is the thickest layer of the Earth. It is not molten as some people mistakenly believe. Due to slow convection forces in the mantle, the crust moves around (plate tectonics).

Outer core: This is a molter layer of iron and nickel.

Inner core: This is a solid core of iron and nickel.
