SOLAR SYSTEM

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: -The Upper Mantle is much stronger than the asthenosphere at about 500-900°C, and the Lower Mantle is denser and hotter, reaching temperatures over 4, 000°C.

Detailed explanation-3: -Below the lithosphere is the asthenosphere layer, a much hotter and malleable portion of the upper mantle. The asthenosphere begins at the bottom of the lithosphere and extends approximately 700 km into the Earth.

Detailed explanation-4: -The Upper Mantle: Temperature and Depth The temperature of the mantle near the crust ranges from 900 to 1600 degrees Fahrenheit. It gets hotter at greater depths. The lower mantle near the core is as hot as 7000 degrees Fahrenheit.

Detailed explanation-5: -The pressure in the asthenosphere ranges from about 14 GPa to 24 GPa, increasing with depth. The pressure continues to increase to over 100 GPa near the bottom of the mantle (the lower mesosphere).

Detailed explanation-6: -The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.
