Question

why does the amount of water vapour decrease rapidly with altitude

Answer 1

Water cycle mainly consists of different complicated processes of moving the water all throughout different reservoirs.

Major processes involved in the amount of water vapour decrease rapidly with altitude are evaporation, interception, precipitation, transpiration, infiltration, retention and detention.

Water vapour performs major functions to the radiation balance of Earth and keeps presence planetary surface warmer.

Answer 2

Answer:

Altitude and height play an important role in vaporization of the water as water vapours are heavy and at higher altitude, the air density decreases. Thus, it becomes difficult for heavier particles that make water vapours to get vaporized. Hence, the rate of water vaporization decreases with increase in altitude.
