The layer of the earth's atmosphere in which gases do not maintain a uniform composition is the Heterosphere.
Heterosphere is simply the layer of an atmosphere in which the gases are split out according to molecular diffusion with an increase in altitude. Therefore, lighter species become more abundant than heavier species.The main components of the heterosphere are oxygen, helium, nitrogen, and hydrogen.
The lower layer is composed of nitrogen and oxygen.In the lower layers of the heterosphere, heavy molecules & atoms are present but lighter ones are present in the upper layer. According to Solar and temperature activities, the boundary between the molecules ranges. The heterosphere lies above the homosphere.
