What is special about the earth’s crust?
The Earth's crust is its lightest, most buoyant rock layer. Continental crust covers 41percent of the Earth's surface, though a quarter of that area is under the oceans. The continental crust is 20 to 80 kilometers thick. Its rocks hold four billion years of Earth history.
Why is the continental crust important?
Importance. Because the surface of continental crust mainly lies above sea level, its existence allowed land life to evolve from marine life.
