In the homosphere the concentration of gases remains the same throughout, and the gases are mixed, always in the same proportions. In the heterosphere the concentration of gases is different in different places, and the gases are typically in the form of layers, rather than mixed together.

The homosphere is the lower part of the Earth's atmosphere where the composition of gases is relatively constant and well-mixed, extending up to about 80 km altitude. In contrast, the heterosphere is the upper part of the atmosphere where gases separate based on their molecular weight, with lighter gases like hydrogen and helium being found higher up.
The stratosphere is part of the homosphere. The homosphere includes the layers of the atmosphere where the composition is relatively uniform, and the stratosphere is one of these layers characterized by the presence of the ozone layer.

The region of the atmosphere that is evenly mixed and behaves as if it were a single gas is the homosphere. This layer extends from the Earth's surface up to about 80 kilometers in altitude and includes the troposphere and most of the stratosphere. In the homosphere, gases are well-mixed due to turbulence and convection processes.
The homosphere is the lower atmosphere, from the Earth's surface up to about 60 kilometers, where the composition of gases is relatively uniform and well mixed. This region includes the troposphere and the lower part of the stratosphere.
The layer of the atmosphere where gases do not maintain a uniform composition is the heterosphere. In the heterosphere, gases tend to separate into layers based on their molecular weights, with lighter gases being found at higher altitudes and heavier gases at lower altitudes.
