    Mar 13, 2018 · 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 Atmosphere's Importance. We are lucky to have an atmosphere on Earth. The atmosphere supports life and is also needed for the water cycle and weather.
    • The Atmosphere and Living Things. Most of the atmosphere is nitrogen, but it doesn't do much. Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life.
    • The Atmosphere and the Sun’s Rays. The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (Figure below).
    • The Atmosphere and Earth’s Temperature. Gases in the atmosphere surround Earth like a blanket. They keep the temperature in a range that can support life.
