Without the protective layer of gases that make up Earth's atmosphere, the harsh conditions of the solar system would render the planet a barren, lifeless husk like the moon. The Earth's atmosphere protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.
Temperature
One of the most important benefits the atmosphere provides is maintaining the Earth’s temperature. On the moon, which has no protective atmosphere, temperatures can range from 121 degrees Celsius in the sun (250 degrees Fahrenheit) to negative 157 degrees Celsius in the shade (negative 250 degrees Fahrenheit). On Earth, however, molecules in the atmosphere absorb the sun’s energy as it arrives, spreading that warmth across the planet. The molecules also trap reflected energy from the surface, preventing the night side of the planet from becoming too cold.
Radiation
The atmosphere serves as a protective shield against radiation and cosmic rays. The sun bombards the solar system with ultraviolet radiation, and without protection, that radiation can cause severe damage to skin and eyes. The ozone layer high in the Earth’s atmosphere blocks much of this radiation from reaching the surface. Dense layers of molecular gases also absorb cosmic rays, gamma rays and x-rays, preventing these energetic particles from striking living things and causing mutations and other genetic damage.

Hello
The atmosphere is shared by every one every people on this earth..When one affects the atmosphere,it affect all of us. with out the atmosphere ,we would find it very hard to survive. humans can last week with out food,days with out water but not with out oxygen and air... A atmospher also protect us from ultraviolet radiation. A thin layer of gas called ozone high up in the atmosphere filters out this dangerous rays ..
Thanks!!
