| q | In thermosphere, oxygen |
||||||||||
| molecules absorb solar rays and |
|||||||||||
| warms the air. |
|||||||||||
| q | Because this
layer has a low air |
||||||||||
| density, the absorption of small |
|||||||||||
| amount of solar energy can cause |
|||||||||||
| large temperature increase. |
|||||||||||
| q | The air temperature in the |
||||||||||
| thermosphere is affected greatly by |
|||||||||||
| solar activity. |
