- Atmospheric Layers
- Troposphere
- Extends from the Earth's surface to about 12km on average
- Temperature decreases with altitude
- The surface warms the Troposphere
- Further from surface, cooler it gets
- Turbulance as warm air rises and cool air sinks
- Lots of clouds as water vapour evaporated from Earth's surface
- Tropopause is boundary between Tropo and Strato
- Stratosphere
- Extends from around 12km to 50km up
- Temperature increases with altitude
- Ozone layer found in lower stratosphere
- UV absorbed in lower strato warms upper
- Not turbulent as not many clouds
- Stratopause is boundary between strato and meso
- Mesosphere
- Extends froom around 50km to 85-90km up
- Temperature decreases with altitude
- Lower Mesosphere warmed by upper strato
- Further away from stratosphere cooler it gets
- Mesopause is boundary between Meso and Thermo
- Thermosphere
- Extendes from 85-90km to around 1000km up
- Temperature increases with altitude
- Small amounts of Oxygen absorb UV radiation
- Air pressure decreases with altitude through the atmosphere
- Troposphere
