SOLAR SYSTEM

Detailed explanation-1: -Mesosphere : The layer that lies above the outer core and beneath the asthenosphere is called the mesosphere. Essentially, it is the lower mantle. Typically it has a depth 350 to 2900 kilometers.

Detailed explanation-2: -Outer Core: The outer core extends from the bottom of the mesosphere or the lower mantle and surrounds the inner core. Composed of iron and nickel, the extreme temperature allows these metals to remain in their liquid phases. It is the only layer of the Earth that is a true liquid.

Detailed explanation-3: -The strong, lower part of the mantle is called the mesosphere.

Detailed explanation-4: -Mesosphere. The mesosphere refers to the mantle in the region under the lithosphere and the asthenosphere, but above the outer core. The upper boundary is defined as the sharp increase in seismic wave velocities and density at a depth of 660 kilometers (410 mi).

Detailed explanation-5: -The lower mantle, historically also known as the mesosphere, represents approximately 56% of Earth’s total volume, and is the region from 660 to 2900 km below Earth’s surface; between the transition zone and the outer core.

Detailed explanation-6: -Asthenosphere –The asthenosphere is made of very viscous, ductile, semi-solid material on which the lithosphere moves. It is a solid that can behave like a liquid, and it is about 440km thick. 3. Mesosphere –The mesosphere is another rigid layer in the earth and it is roughly 2, 200km in thickness.
