➡️ Importance of Atmosphere

Atmosphere contains,

•Air, which is a mixture of all gases, dust particles and water vapour. Nitrogen is the most abundant gas as it forms 78% of the total volume of atmosphere. Oxygen is 21% by volume and carbon dioxide just 0.03%. There are trades of other gases like Agron, helium, and Methane.

•Oxygen in Atmosphere is used by plants and animals to respire. Green plants take up Carbon dioxide from air to carry out photosynthesis. Carbon dioxide also absorbs heat radiated by the sun and thereby keeps the earth warm. This is known as green house effect.

• Nitrogen helps in growth of living organisms and in maintaining fertility of the soil.

•The layer of Ozone gas in the atmosphere saves us from the harmful UV rays of the sun.
