Answer 2

The word rarefied means thin, in the sense not dense.

When it comes to air, rarefied air refers to the air of the high altitude peaks where one finds lesser density air.

When you are high up on a mountain, it gets difficult to breathe due to the rarefied air.

Sometimes fog is heavy and when it subsides, you can breathe a little easier.
