Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
The atmosphere has different layers.
Temperature varies in each layer.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the temperature variations in atmospheric layers.
Step 3: Detailed Explanation:
The coldest region of the atmosphere is the mesopause.
It is the boundary between mesosphere and thermosphere.
Temperature decreases with height in the mesosphere.
At the mesopause, temperature can be as low as -90°C.
Tropopause and stratopause are warmer.
Thus, the mesopause is the coldest region.
Step 4: Final Answer:
The coldest region of the atmosphere is the mesopause.
Hence, the correct option is (C).
The atmosphere has different layers.
Temperature varies in each layer.
Step 2: Key Formula or Approach:
