Page 7 - WEATHER ,AIR AND WATER

WATER:

• Air contains water vapour. Humidity is the

amount of water vapour present in air.

• As the warm air rises up it takes the water

vapours with it. These water vapours form

clouds.

• Cool water vapours condense and form water

droplets .These water droplets become heavy

and fall down as rain.

• In extreme cold regions, water droplets fall

down in the form of snow.
