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.
