With reference to "water vapour", which of the following statements is/are correct? 1. It is a gas, the amount of which decreases with altitude. 2. Its percentage is maximum at the poles. Select the answer using the code given below:
1 only
2 only
Both 1 and 2
Neither 1 nor 2
Solution
Water vapour content decreases rapidly with altitude (Statement 1 correct). It is maximum near the equator (warm, humid regions) and minimum at the poles (cold, dry) — so Statement 2 is wrong.
