Earth's troposphere layer is which of the following?

73% Answer Correctly

	hottest
	farthest from the surface
	coldest
	closest to the surface

Solution

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.
