Presentation transcript:

 Earth’s atmosphere is divided into several different atmospheric layers extending from the Earth’s surface outward: › Troposphere › Stratosphere › Mesosphere › Thermosphere › Exosphere

 Troposphere Temperature: › As altitude increases, temperature decreases!

 Troposhpere Gases: › Nitrogen and oxygen are found in ALL layers of the atmosphere › There are other trace gases in the troposphere

 Troposphere Air Pressure: › Greatest amount of pressure

 Troposphere Interesting Facts: › Where we live › Where weather happens

 Stratosphere Temperature: › Cold!

 Stratosphere Gases: › Nitrogen › Oxygen › Ozone

 Stratosphere Air Pressure: › Decreases as you move through the layers

 Stratsosphere Interesting Facts › Planes fly in this layer › This is where the ozone layer is › Absorbs ultraviolet radiation (UV)

 Mesosphere Temperature: › Coldest Layer

 Mesosphere Gases: › Nitrogen › Oxygen

 Mesosphere Air Pressure: › Decreases as you move through the layers

 Mesosphere Interesting Facts › Meteroids burn up in this layer › This can cause meteor trails.
