What are some uses of air?
Answers
Answer:
Important Uses of Air
- Sustain life and growth.
- Combustion.
- Maintaining Temperature.
- Supplier of Energy.
- Photosynthesis.
Without the presence of air , life would be impossible, and other planets in our Solar system are the evidence of that. Hence, it is a natural resource that supports life on Earth.
It is a significant supplier of energy: all living plants and animals depend on oxygen to generate valuable energy. Body cells take oxygen from the blood and produce energy after consuming food in the form of ATP. This biochemical generation of ATP is essential to maintain life on the Earth. So, this is one of the uses of air.
It is a conducting medium for sound: we can hear the sound of speech or noise, etc. only when there is the air around us. It happens because the wind is a good sound conductor. Without a medium, we will not be able to hear anything and won't be able to produce the sounds.
It is an important part of the water cycle: the water cycle is a phenomenon of water from the soil, the oceans and seas evaporating due to the heat of the sun and forming clouds. These clouds move towards the land surface, and they are cooled by wind and rain. This rainwater once again reaches the sea and ocean.
It is responsible for the pollination of crops: plants produce male gametes in pollen grains. These pollen grains move from the male flower to the female flower and combine with female gametes, which is called pollination. This may occur in flowers growing on the same plant or between remote plants with the help of wind power. It keeps the balance of the temperature on the Earth's surface when it's summer. When the sun strongly heats the Earth's surface, the surface temperature of the ground is growing rapidly, but it grows slowly on the surface of the ocean or sea (this is because a solid substance is heated faster than liquid water). Thus, the air that is warmed at the Earth's surface rises up, and the cold one from the sea surface transfers to the surface of the ground which minimizes the temperature rise.
It helps in drying (moisture balance): the ground being wet from the rain dries due to air. On a wet surface, it is very moist. Thus, the moist layers are replaced by less humid or dry layers of air. The new dry layer on the surface absorbs moisture from the wet surface, and the cycle continues until the surface is dry.
