Mesosphere

The transcript explains the mesosphere, which is a part of both the Earth's atmosphere and mantle. In the atmosphere, it lies between 50 to 85 kilometers altitude, below the thermosphere, and is the highest part that is evenly mixed. In geology, the mesosphere refers to the lower part of the Earth's mantle, situated between the outer core and the upper mantle.
