Near which boundary is the coldest part of the atmosphere found?
Answer and explanation
Correct answer: Mesopause
The mesopause is the boundary between the mesosphere and thermosphere, and it is generally the coldest region of Earth’s atmosphere. As altitude rises through the mesosphere, temperature falls considerably; above the mesopause, it begins to increase in the thermosphere. Therefore, option D is correct. Tropopause and stratopause are different boundaries, while thermopause is not the usual answer for the coldest region.
