Why is the mesopause considered the coldest region of the atmosphere?
Answer and explanation
Correct answer: Temperature keeps decreasing upward in the mesosphere
The mesopause is the upper boundary of the mesosphere. In the mesosphere, temperature generally falls as altitude increases, so the temperature reaches its minimum near the mesopause before the thermosphere begins and the trend reverses. Therefore option D is correct. Carbon dioxide is not completely absent, sea winds cannot reach this region as ordinary weather systems, and a thick cloud layer is not the reason for the extreme cold.
