Can i get 20 facts about the earths crust?

The crust is deepest in mountainous areas.

It can be up to 70km thick here.

The continental and oceanic crusts are bonded to the mantle, which we spoke about earlier, and this forms a layer called the lithosphere.

This layer is cool and rock solid.

The crust is the thinnest layer of the Earth.

It has an average thickness of about 18 miles (30km) below land, and around 6 miles (10km) below the oceans.

The crust is the layer that makes up the Earth's surface and it lies on top of a harder layer, called the mantle.
