Which best describes Earth's mantle?

Answer 1

The best description of Earth's mantle is that it is a layer of semi-solid, hot rock located between the outer core and the Earth's crust. It is the largest layer of the Earth, making up about 84% of its volume. The mantle is composed of silicate minerals rich in iron and magnesium and experiences extremely high pressures and temperatures. It is responsible for the movement of tectonic plates and convection currents, playing a crucial role in shaping Earth's surface and geological processes.
