When the light rays pass through theatmosphere having layers of different densities and refractive indices, thenrefraction of light takes place. Thisrefraction of light by the earth'satmosphere is called “atmospheric refraction”.

Atmospheric Refraction....
Refraction which takes place from Earth's atmosphere is called atmospheric refraction.
Different layers of Earth's atmosphere have different densities. Hence when light passes from it , it gets refracted .
Application of atmospheric refraction.
Twinkling of stars.....
In fact stars does not twinkle , they appear twinkling bcz of atmospheric refraction . When the star light passes from Earth's atmosphere it gets refracted and the star twinkles.
Planet does not twinkle bcz they don't have the light of their own . They are closer to the Earth , they are extending source of light and they nullify twinkling effect.
