Earth's 25-mile deep crust — just 1% of its mass — contains all known life
Earth has four layers: the crust, the mantle, the outer core, and the inner core. The crust is made of solid rocks and minerals.

Today, tectonic activity is responsible for the formation (and destruction) of crustal materials.
