Earth's troposphere layer is which of the following?
hottest |
|
farthest from the surface |
|
closest to the surface |
|
coldest |
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.
