Consider the following observations:
1. At higher elevations, green house effect is weaker in comparison to lower elevations
2. Temperature inversions commonly appear on clear, calm nights
Which among the above is / are correct statements?

Answer: [C] Both 1 & 2

First statement is true because at high elevations, air temperatures are generally cooler and have a greater dayto- night range. Both effects occur because the thickness and density of the air column above decrease with elevation; therefore, the greenhouse effect is weaker at high elevations. The second statement is correct because in a temperature inversion, air temperature does not decrease with height, but increases instead. Temperature inversions commonly appear on clear, calm nights
