The mantle is a thick layer of rock located between the Earth's crust and the outer core, constituting about 84% of the Earth's total volume. It plays a crucial role in tectonic processes, as it is involved in mantle convection, which drives plate movements and influences volcanic activity. The mantle is composed mainly of silicate minerals and is divided into the upper and lower mantle, each with distinct physical properties.
