Normally, the temperature decreases with the increase in height from the Earth’s surface, because
- the atmosphere can be heated upwards only from the Earth’s surface
- there is more moisture in the upper atmosphere
- the air is less dense in the upper atmosphere
Select the correct answer using the codes given below:
Detailed Explanation:
✅ Statement 1 – Correct: The atmosphere is transparent to incoming solar radiation but is primarily heated from below by long-wave terrestrial radiation emitted from Earth's surface, making lower layers warmer.
❌ Statement 2 – Incorrect: Water vapor and moisture are concentrated in the lower atmosphere (troposphere), not the upper atmosphere, which is significantly drier.
✅ Statement 3 – Correct: At higher altitudes, air pressure decreases making air less dense; rising air expands and undergoes adiabatic cooling, and thinner air has lower capacity to absorb and retain heat.
