Question

What is the average thickness of the earth’s crust?

Answer 1

The average thickness of the earth’s crust varies depending on location. On the continents, it is about 30-35 kilometers thick, while beneath the oceanic beds, it is much thinner, about 5 kilometers. In some mountainous regions such as the himalayas, the crust can be as thick as 70 kilometers. This outermost layer constitutes only about 1% of earth’s volume but forms the base for the biosphere where life exists.
