Earth's atmosphere surrounded with thin layers of gases. The main gases and
their precentages are 78% nitrogen, 21% oxygen, .9% argon, and .03% carbon dixide. The atmosphere is formed from
planetary degrassing, which is the process when gases are released from the interior of the Earth coming from volcanoes.
The Layers of Earth
- Thermosphere: a thermal arrangement of the atmosphere
- Exosphere: the outer layer of Earth's atmosphere
- Ionosphere: has several ions and free electrons, begins at about 43-50 miles high and proceeds for hundreds of miles
- Mesosphere: featured by temperatures that rapidly fall as height grows
- Stratosphere: featured by a slight temperature increase with altitude and the absence of clouds.
- Trapopause: the limit zone, or transition layer, between the Stratosphere and Traposphere
- Traposphere: lowest region in Earth's atmosphere
