SOLAR SYSTEM

Detailed explanation-1: -The asthenosphere is below the lithosphere It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid. The rocks in the asthenosphere are not as dense as the rocks in the lithosphere. This allows the tectonic plates in the lithosphere to move around on the Earth’s surface.

Detailed explanation-2: -Asthenosphere composition and structure Rock in the asthenosphere is close to the melting point. The temperature sits at around 1500°C, give or take 100°C. But it avoids melting because the pressure keeps it solid. For any type of rock, the melting point corresponds directly to the pressure exerted on it.

Detailed explanation-3: -Below the plates is the asthenosphere, a solid but soft layer of the upper mantle. The asthenosphere is squishy-it can deform and flow, though extremely slowly-so that the heavy plates literally float on top of it.

Detailed explanation-4: -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.
