GENERAL GEOLOGY

Detailed explanation-1: -The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten.

Detailed explanation-2: -Mantle. Just below the crust lies the mantle. The mantle is semi-liquid, sort of like a malleable plastic and makes up 84% of Earth’s volume. Earth’s mantle is 2, 900 km thick and is broken down into 3 main zones, the lithosphere, asthenosphere, and mesosphere.

Detailed explanation-3: -The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth. The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick.

Detailed explanation-4: -The Mantle: The mantle is the thickest layer of the Earth, making up about 82% of its volume. The mantle is composed primarily of heavy metals, such as iron, nickel, magnesium, and others. Scientists describe the state of the mantle as ‘plastic.

Detailed explanation-5: -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.
