Answer 2

Answer:Warm air containing water vapour rises; with an increase in altitude, pressure decreases resulting in an expansion of the air mass; the rising air cools as it expands at the rate of 1� C for every 100 m rise in elevation. A stage is reached when the air is cooled beyond its saturation point and it can no longer hold all the water vapour in the gaseous phase; the surplus vapour condenses to form raindrops. A saturated cubic metre of air contains 39.4 g of water vapour at 35�C; at 20�C, 17.3 g; at 10�C, 9.4 g; at 0�C, 4.8 g; and at - 10�C only 2.1 g. The condensation of the excess vapour releases latent heat to the air mass so that it rises still higher and the process continues.

The rising air will continue to ascend only as long as it remains warmer than the surrounding atmosphere at any level. Rising air tends to accumulate at higher altitudes preventing the upward motion of the air from below, unless wind at the higher level carries away the rising air.
