Based on composition,how is the atmosphere divided?

Question

Quizplus · Accepted Answer

The atmosphere is divided into two broad classifications based on composition, which are the homosphere and the heterosphere. The homosphere is the lower region where the composition is almost uniform, and the heterosphere is the upper region where the composition is not uniform and is stratified by mass. The other options mentioned, such as one continuous region, functional areas that absorb radiation from the Sun, and the troposphere and the stratosphere, do not accurately describe the division of the atmosphere based on composition.
