- Front
- Back
|
troposphere
|
- lowest layer of the earths atmosphere
- Earth's weather occurs here - Extends 16 km above Earth's surface - increase altitude = increase temperature and decrease pressure |
|
|
Tropospause
|
- this is where the jet stream is located
|
|
|
stratosphere
|
- 16 km-50km above earth's surface
- contains layer of ozone which absorbs energy from the sun and converts it to heat |
|
|
mesosphere
|
- major drop in temperature up to -90*c
- between 50 and 80 km above earth - protects us from being hit by meteoroids |
|
|
thermosphere
|
-outermost layer with no definite outer limit
- very hot because it is the first layer to absorb solar radiation - converts solar radiation to heat |
|
|
ionosphere
|
- ends at 550 km
- electrically charged particles, radio waves bounce off these - Aurora borealis know how this works, in detail |
|
|
exosphere
|
- outermost layer
- satellites travel in this layer (TV and phone signals travel through here) |
