Layers of the Earth
... The Earth has several distinct layers: The crust – the outermost layer of the Earth, comprised of 2 types of crust - continental and oceanic. The crust has a variable thickness, being 35-70 km thick in the continents and 5-10 km thick in the ocean basins. Continental crust has a varying thickness, b ...
