Earths Structure And Layers Questions Medium
The mantle is the layer of the Earth located between the crust and the core. It is primarily composed of solid rock, specifically silicate minerals rich in iron and magnesium. This layer is divided into two parts: the upper mantle and the lower mantle. The upper mantle consists of both solid and partially molten rock, while the lower mantle is mostly solid due to the high pressure. The mantle plays a crucial role in the dynamics of the Earth, as it is responsible for convection currents that drive plate tectonics and volcanic activity.
