Without the protective layer of the gases that make up the earth’s atmosphere, the harsh conditions of the solar system would render the planet lifeless. 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. The earth’s atmosphere regulates the earth’s temperature. On the moon,which has no protective atmosphere, temperatures can range from 121 degrees to – 157 degrees celsius On earth, however, molecules in the atmosphere absorbs the sun’s energy as it arrives, spreading the warmth across the planet. The molecules also trap reflected energy from the surface, preventing the nights from becoming too cold.

The atmosphere serves as a protective shield against radiation and cosmic rays. Without this protection, that radiation can cause severe damage to the skin and eyes. The ozone layer located high in the earth’s atmosphere blocks most of this radiation from reaching the surface of the earth.

The atmosphere also serves as a medium for the movement of water. Vapour evaporates out of oceans, condenses as it cools and falls as rain providing life-giving moisture to otherwise dry areas of the continents. Without the atmosphere, it would simply boil away into space, or remain frozen in pockets below the surface of the planet.
