Question

differentiate between mesosopher and barosphere

Answer 1

The mesosphere is the piece of mantle underneath litosphere or more the external center.

The focal piece of the earth, underneath the lithosphere.

The layer which isolates outside and mantle is called Mohorovic intermittence.

I think barosphere implies part where earth can apply enough weight for gases to exist

Answer 2

Barosphere is the part of the atmosphere, below the exosphere, whereas mesosphere is above the troposphere and below the thermosphere.

Barosphere constitutes troposphere, stratosphere, mesosphere and thermosphere, whereas mesosphere is just part of the larger Barosphere.
