|
|
|
Define: Climate
|

|
|
|
Air
|
- A mixture of gases surrounding us
- density = mass/volume - factors that affect density = temperature and water content. |
|
|
Atmosphere
|
- begins at sea level
- atmospheric pressure decreases with altitude - Layers "Tasty Surf Makes Tommy Excited" - Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere. |
|
|
Troposphere
|
- Bottom layer
- temperature decrease in altitude a.k.a. environmental lapse rate. |
|
|
Stratosphere
|
- tropopause between troposphere and stratosphere
- temperature increases due to presence of the ozone layer - temperature increases to an altitude of ~ 50km above the surface |
|
|
Mesosphere
|
- Temperature decreases until ~80km above surface
- coldest atmospheric temperatures |
|
|
Thermosphere
|
- Atmospheric density is extremely low
- Temperature increases to 1000°c with altitude caused by absorption of short wave UV radiation - ionosphere - layer of ionisation and the place where the Aurora are produced |
|
|
Exosphere
|
- outside atmosphere
- extremely tenuous gas laws |
