Why would the Earth be barren without the atmosphere?​

The layer of air around us is called Atmosphere. Following is the importance of atmosphere: -

(a) It gives us life giving gases like oxygen for breathing of animal kingdom and carbon dioxide is inhaled by plant kingdom.

(b) It has Ozone layer which protects us from the harmful ultraviolet rays of the sun.

(c) There are tiny dust particles in the atmosphere which helps in the formation of the rain droplets.

(d) It acts as a blanket which prevents the earth from becoming too hot during day and too cold during night.

(e) It protects us from falling meteors and other cosmic dusts. They burn when coming in contact with the atmosphere.

(f) Presence of gases, dust particles and water vapours lend colours to the sky.

Thus, atmosphere plays a very vital role and in its absence there won't be any life and earth will be barren.
