Air is the mixture of different like nitrogen, oxygen, carbon dioxide etc.

Air contains 78 part nitrogen, 21 part oxygen and remaining 1 part other gases.

Wind is the movement of air.

There are mainly two types of wind-global wind and local wind.

Wind is very useful because living organisms inhale air to be alive.

Wind is also needed for the growth of plants, cooking, electricity generation, transportation etc.

Various smokes, excretion of living organisms, garbage in improper places, are the reasons for the germs in air.

Polluted air and water is harmful for living organism. Polluted sound is the unbearable and unpleasant sound which is also harmful.

Potable water means drinking water.

Water has three states – solid, liquid and gas.

Water on earth always changes its form and this change makes a cycle.

Addition or subtraction of heat makes the water cycle work. For example, if heat is given to ice, it melts. If heat is added to water, it evaporates to get converted into gas (water vapors).

The degree of hotness and coldness is called temperature.
