Layers of the Atmosphere
Study online at https://quizlet.com/_17ctbx
1. Atmosphere Mixture of gases that surrounds Earth
- provides the oxygen that organisms need to live
-protects the earth from harmful UV radiation from the sun
2. Nitrogen Makes-up 78% of the atmospheric gases
- Most common and abundant atmospheric gas
- is released when dead plants and dead animals break
down and when volcanoes erupt
3. Oxygen 21% of atmospheric gases
-the second most common atmospheric gas
-is made by phytoplankton and plants- released when
plants go through Photosynthesis
4. Carbon Dioxide greenhouse gases found in the atmosphere
and Water Vapor
5. Troposphere -gases mix continuously in this layer
- the layer in which weather occurs
- contains 90% of the atmosphere's mass

-densest atmospheric layer
-lowest layer of the Earth's atmosphere
6. Stratosphere home of the ozone layer
Ozone layers protects us from the sun's harmful UV ray
gases do not mix in this layer
7. Mesosphere Coldest layer
Meteors burn up in this layer
8. Thermosphere This layer has very high temperatures, but doesn't feel hot
-Divided into two layer (exosphere and ionosphere)
-Lowest air pressure-air very thin
-Energy from the sun strikes this layer first
9. Gravity the force that holds the Earth's atmosphere around Earth
10. Air pressure
