Answer:
Air is a mixture of different gases. The most mportant gas in the atmosphere in terms of olume is nitrogen (78%), followed by oxygen 21%).) The remaining volume of the air in the atmosphere is made up of a number of gases n including argon, carbon dioxide, ozone and water vapour.
Explanation:
All the gases present in the atmosphere are very important for us. We breathe in oxygen without which no life is possible. Nitrogen plays an important role in controlling and burning of substances, Ozone absorbs the harmful ultraviolet radiations coming from the sun. The water vapours present in the air are the basis of all precipitation.
Carbon dioxide is another important gas. Green plants use carbon dioxide to make their food and release oxygen. Humans or animals release carbon dioxide. The amount of carbon dioxide released by humans or animals seems to be equal to the amount used by the plants which make a perfect balance. However, the balance is upset by burning of fuels, such as wood, coal, dung and oil. They add billions of tons of carbon dioxide into the atmosphere each year. As a result, the increased volume of carbon dioxide is affecting the earth's weather and climate.
