Question

3 sentence summary of the earths crust

Answer 1

The Earth's crust is the outermost layer of the planet, composed of a variety of rocks and minerals, and varies in thickness from about 5 kilometers (3 miles) under the oceans to up to 70 kilometers (43 miles) beneath mountain ranges. It is divided into two types: the continental crust, which is thicker and predominantly composed of granitic rocks, and the oceanic crust, which is thinner and primarily made up of basaltic rocks. The crust plays a crucial role in geological processes, including plate tectonics, which shapes the Earth's landscape and contributes to phenomena such as earthquakes and volcanic activity.
