The Earth's crust is the cold, solid, outermost layer of its lithosphere, which sits above the hot convecting asthenosphere. It is divided up into plates and consists of two types: the dense ocean crust and the lighter continental crust. The Himalaya mountains in China is where the Earth's crust is thickest, with a thickness variable from 40 to 75 km (24.85 to 46.6 miles).
