Explanation:
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.
