The middle mantle is just above the lower mantle.
Mesosphere lies above the core.
The lower mantle of the Earth is the layer directly above the core. It is very dense, hot, and composed of thick rock.
The mesosphere is the sphere that contains the lower mantle. It is located above the outer core and under the lithosphere and asthenosphere.

The Lower Mantle
The lower mantle is beneath the crust.
The upper mantle and the lower mantle.
Working outwards from the centre: The Earth is believed to be formed of an inner core, outer core, inner mantle, outer mantle, and the crust. The mantle is two thousand miles thick and makes up more than three-quarters of the Earth's volume.
The lower mantle is older and cooler than the upper mantle. Thank you for reading this I'm comment if you like one direction(: hehe
The upper mantle is harder than the lower mantle
Well there is the crust, upper mantle, lower mantle, outer core, and the inner core. So, the lower mantle is the 3rd one down.
