The middle mantle is just above the lower mantle.
The Lower Mantle
The Earth's mantle is approximately 2,900 kilometers thick and is composed of solid rock that lies between the Earth's crust and core. It is mainly made up of silicate minerals and is responsible for convection currents that drive plate tectonics and other geological processes on the planet.
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
It is 2,900 kilometers
The lower mantle is beneath the crust.

The upper mantle and the lower mantle.
The lower mantle is located in the middle layer of the Earth's interior, known as the mantle. The mantle is divided into two main regions: the upper mantle and the lower mantle. The lower mantle is situated beneath the upper mantle and above the outer core.
The mantle is the thickest layer of the Earth, extending from the crust to the outer core. It accounts for approximately 84% of Earth's volume and is composed of solid rock that is capable of flowing over long periods of time.
