The Earth's atmosphere is a blanket held in place by gravity and Earth's motion. The location of the Earth relative to the sun and the greenhouse effect of the atmosphere makes Earth a hospitable place for our kind of life
The Greenhouse Effect
The average temperature on the Earth's surface is warmed to 14 Degrees C, due to the Greenhouse effect.
The Greenhouse effect is caused by the gases that make up the atmosphere.
These gases increase the temp on the surface by reflecting back to the surface a portion of the radiation energy emitted by the surface.
The emitted energy is a part of the solar energy received by the Earth's surface.
Contributions to the Greenhouse Effect
Different gases in the atmosphere influence the greenhouse effect in different amounts.
Under a clear sky:
Water vapor: ~60%
(can range between 36% and 72%)
Carbon Dioxide:~25%
(can range between 9% and 26%)
Ozone: ~8%
(can range between 3 and 8%)
Trace gases ~7%
(methane between 4% to 9%
Nitrous oxide between 3% and 9%)
Clouds add to the greenhouse effect.
