GEOLOGY

Detailed explanation-1: -The mantle is the mostly solid bulk of Earth’s interior. The mantle lies between Earth’s dense, superheated core and its thin outer layer, the crust. The mantle is about 2, 900 kilometers (1, 802 miles) thick, and makes up a whopping 84 percent of Earth’s total volume.

Detailed explanation-2: -Mantle-In general, the Earth’s mantle lies beneath the crust and above the outer core, averaging about 1, 802 miles (2, 900 kilometers) thick and repre· senting 68.3 percent of the Earth’s mass.

Detailed explanation-3: -The Earth’s core accounts for 15% of Earth’s volume but more than 30% of the mass, the mantle for 84% of the volume and close to 70% of the mass, while the crust accounts for less than 1% of the mass.

Detailed explanation-4: -The mantle is composed of the mesosphere and the asthenosphere and the uppermost part of the mantle. That uppermost part of the mantle is what is combined with the crust to make the lithosphere.

Detailed explanation-5: -Earth’s mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 1024 kg and thus makes up 67% of the mass of Earth. It has a thickness of 2, 900 kilometers (1, 800 mi) making up about 84% of Earth’s volume.
