Question:
Consider the following statements with reference to structure of the Earth’s atmosphere:
1. Thickness of the troposphere is greatest at the equator
2. The air temperature of the tropopause is highest above the poles
3. The temperature in troposphere decreases at the rate of 1°F for every 165 m of height
Which of the statements given above is/are correct?

Which of the statements given above is/are correct?
Options:
- 1 only
- 1 and 2 only
- 2 and 3 only
- 1, 2 and 3
- 1 only
- 1 and 2 only
- 2 and 3 only
- 1, 2 and 3
Correct Answer: 1 only
Explanation:
The troposphere is thickest at the equator due to higher surface heating. The tropopause is coldest above the poles. The temperature in troposphere decreases at the rate of 6.5°C per kilometre (not 1°F per 165 m).
