What is thickness of the lithosphere?

The thickness of the lithosphere varies widely depending on the location of the Earth's crust. It can be between 5 and 70 kilometers thick on average. The lithosphere under the oceans has a thickness of about 5-10 kilometers, while the continental lithosphere can be between 30-70 kilometers thick. Additionally, the thickness of the lithosphere changes over geological time as tectonic plates move or continents drift apart. The thickness also varies depending on the age of the crust, with younger crust being thinner than older crust. Overall, the thickness of the lithosphere is an important factor in understanding the geology and dynamics of the Earth's surface.
