Atmosphere
The atmosphere is an important
part of what makes Earth livable.
Atmosphere is the envelope of
gases surrounding the earth or
another planet. Our atmosphere
gives us oxygen to survive. It gives
carbon–dioxide for plant’s
survival. It maintains the
temperature on the earth.
Atmosphere (ozone layer) also
protects us from many harmful
rays like ultra violet rays.
