Hey buddy here is ur answer !!!

1. Essential supplier of energy: All living beings including plants & animals are dependent on air oxygen for generation of valuable life energy. Body cells take up oxygen from the blood and generate energy from food in the form of ATP. This biochemical generation of ATP is an essential requirement to sustain life on earth.

2. Air is a conducting medium for sound: We can hear the sound of speech or cry or noise etc. only in the presence of air. This is because air is a good conductor of sound. Without air, we do not or cannot hear sounds.

Even the music instruments make use of resonance and bass with the alteration of air and sound combination.

Uses of Air 3. Air supports water cycle: Water cycle is a phenomenon wherein water from the soil, oceans and seas is evaporated due to Sun’ s heat and form clouds.

3. Air supports water cycle: Water cycle is a phenomenon wherein water from the soil, oceans and seas is evaporated due to Sun’ s heat and form clouds.

These clouds travel on to the land surface, get cooled by air and shower as rain. This rainwater somehow again reaches the Sea and Oceans. So air helps in transfer or movement of clouds towards the earth surface and also cools them to shower the rain.



Hence we can find heavy rains at places of many trees as the air gets cooled there in comparison to deserts.

4. Air helps in pollination of crops: Plants produce male gametes in the form of pollen grains. This pollen travels from male flower to female flower and unites with female gametes. This is called as pollination. This can happen within flowers of the same plant or between distant ones through air wind. Thus air helps in cross-pollination in plants. Henceforth going into a grown farm causes nasal stuffiness as the pollen cause allergy to nasal tract when breathed in. This helps in agriculture as cross-pollination leads to higher yield.

5. Air maintains temperature on the earth surface: During summers when there is abundant sunshine, the temperature of earth’s surface rises rapidly but slowly on ocean or sea surface (this is because solid surface gets heated faster than liquid water). So air which gets heated on earth surface rises and cold air from sea surface moves on to the earth surface thus minimizing the rise in temperature.



6. Bring monsoon: Monsoons are the ones by which we have rains in the rainy season. This is done due to currents of wind (air) across the earth surface. Lack of wind can delay monsoons and rains and thereby deplete water levels for drinking, irrigation and another usage in our daily lives.

7. Air helps in transport: Air transport by flights and helicopters has come into widespread use. Even for birds and insects air is the chief mode of transport.Uses of Air

Air transport is quicker than land and water transport. There is less friction, so the vehicles travel faster. Further, the travel is in vector mode, i.e., from one point to another in a straight direction (so shortcut route). So the journey has fewer obstructions making the transport very fast.

8. Aerodynamics in landing: Parachutes, hot air balloons are used to land from flights in case of need safely.

Uses of Air

These flying chute reach the land safely due to buoyancy and pressure of air upwards.

9. Air helps in drying (humidity balance): Land when gets wet by rains is dried due to air. The air on the immediate wet surface is very moist. So these moist layers of air are replaced by less moist or dry layers of air. The new dry layer on the surface takes up moisture from wet surface and the cycle continues till the surface dries. Thus air help in drying by maintenance of humidity. Even our clothes when washed gets dried by same manner.

10. Air helps in normalizing Temperature: A piece of ice melts due to air and hot piece of metal cools due to air. Here air acts as a heat conductor and tries to bring these materials to normal surrounding temperature. Hence the phenomenon of ice melting and metal cooling is seen.

11. Air helps reduce friction in tires: Another area where the importance of air is prominent is automobiles.

Since the time of automobile emergence, their wheels are filled with air inside the rubber tubes of wheels.
