The inferior mantle, also known as the lower mantle, is the portion of the Earth's mantle that extends from about 660 kilometers (410 miles) to approximately 2,900 kilometers (1,800 miles) deep. It is characterized by high pressure and temperature, leading to the solid state of silicate minerals, though they can flow slowly over geological timescales. This layer plays a crucial role in mantle convection, which drives plate tectonics and influences volcanic activity.
