Detailed explanation-1: -The asthenosphere is the next mechanical layer. It consists of the solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere. Because the asthenosphere can flow, it bends and deforms instead of breaking under stress.

Detailed explanation-2: -The plates move on a hot flowing mantle layer called the asthenosphere, which is several hundred kilometers thick. Heat within the asthenosphere creates convection currents (similar to the currents that can be seen in the lava lamp).

Detailed explanation-3: -Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth’s tectonic plates and allowing them to move. Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust.

Detailed explanation-4: -The upper mantle extends from the crust to a depth of about 410 kilometers (255 miles). The upper mantle is mostly solid, but its more malleable regions contribute to tectonic activity.

Detailed explanation-5: -The asthenosphere exists as a soft layer of solid but malleable rock that can cause the tectonic plates to move and shift. Researchers have wondered what factors make the asthenosphere soft and considered molten rocks to be part of the equation.
