Question

Quizplus · Accepted Answer

The Earth's crust is indeed thickest under mountain ranges, where it can be up to 70 kilometers thick due to the accumulation of materials and geological processes that form mountains. In contrast, the oceanic crust is much thinner, averaging about 5-10 kilometers thick, as it is primarily formed from basaltic rocks that spread and thin out from mid-ocean ridges.
