The primary component of the Earth's mantle is silicate minerals, primarily composed of olivine, pyroxene, and garnet. This layer lies between the Earth's crust and core and constitutes a significant portion of the Earth's volume. The mantle's properties, such as temperature and pressure, influence geological processes like plate tectonics, volcanism, and the creation of Earth's landforms. The mantle is crucial for understanding how heat and materials are transferred within the Earth, driving dynamic processes essential for shaping the planet's surface.
