Question

The crust under the ocean bottom is thinner than the crust under the continental surface?

Answer 1

Yes, the crust under the ocean bottom is thinner than the crust under the continental surface.

Step-by-step explanation:

Yes, the crust under the ocean bottom is thinner than the crust under the continental surface. Oceanic crust, which covers 55% of Earth's surface, is typically about 6 kilometers thick and is composed of basalt, while continental crust, covering 45% of the surface, is 20 to 70 kilometers thick and mostly composed of granite. The average thickness of the crust on land is 35 kilometers, while under the oceans it is 5-6 kilometers.
