The Earth's mantle extends from about 35 kilometers (22 miles) below the Earth's surface to approximately 2,900 kilometers (1,800 miles) deep, reaching the outer core. It makes up about 84% of the Earth's total volume and is primarily composed of silicate minerals rich in iron and magnesium. The mantle is divided into the upper and lower mantle, with the upper mantle being more rigid and the lower mantle being more fluid in nature.
