Detailed explanation-1: -Relative Humidity. Probably the best known measure of water vapor in the air is relative humidity.
Detailed explanation-2: -The maximum amount of water vapor that can be in the air depends on the air temperature. Warmer air can hold more water vapor within it. That’s why the muggiest days usually happen at the height of summer heat. But as the temperature goes down, the air can hold less vapor and some of it turns into liquid water.
Detailed explanation-3: -Therefore, the correct option is(D): Photosynthesis.
Detailed explanation-4: -Global mean water vapour is about 0.25% of the atmosphere by mass and also varies seasonally, in terms of contribution to atmospheric pressure between 2.62 hPa in July and 2.33 hPa in December.
