WebThe mantle is the thickest layer of the Earth at 2,900km thick. It makes up nearly 80% of the volume of the Earth. The mantle itself is divided into 2 layers, the upper and lower mantles and the heat within these layers drives convection currents. The upper mantle is semisolid rock called magma that flows slowly due to convection currents. WebThe crust of Earth is of two distinct types: Oceanic: 5 km (3 mi) to 10 km (6 mi) thick [4] and composed primarily of denser, more mafic rocks, such as basalt, diabase, and gabbro. Continental: 30 km (20 mi) to 50 km (30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite.
