Term
| Know the 6 layers of the atmosphere from Earth's surface up |
|
Definition
| Troposphere, Stratosphere, Mesosphere, Thermosphere which includes the Ionosphere and the Exosphere |
|
|
Term
| As you go higher in the Stratosphere |
|
Definition
| Temperature increases (no ozone layer to protect it from the sun's heat) |
|
|
Term
| Know what happens to temperature, your breathing, and air pressure and why when you climb a mountain 6km above sea level |
|
Definition
| Temperature decreases because in the troposphere temperature decreases as altitude increases, Breathing increases because oxygen molecules are more spread apart at higher altitudes and there are fewer oxygen molecules to breathe in each time, Air Pressure decreases because as altitude increases air has less density. |
