Earth's breathable air is held in which atmospheric layer?
troposphere |
|
mesosphere |
|
stratosphere |
|
thermosphere |
The Earth's atmosphere has several layers starting with the troposphere which is closest in proximity to the surface. Containing most of the Earth's breathable air (oxygen and nitrogen), it's a region with warmer temperatures closer to the surface and cooler temperatures farther away which results in the rising and falling air that generates weather.
