There are two different types of crust close crust The thin layer that is the outermost section of the earth. It varies from between 5 – 70 km in depth and is broken up into several large pieces ...

Geophysicists divide oceanic crust (beneath any sedimentary material) into two basic layers, layer 2 and layer 3. Layer 2 is typically subdivided further into layers 2A and 2B.
