The heterosphere is divided into several distinct regions based on the distribution of gases by molecular weight. These regions include the exosphere, thermosphere, and mesosphere. The exosphere is the outermost layer, containing mainly light gases like hydrogen and helium, while the thermosphere contains heavier gases like oxygen and nitrogen. The mesosphere sits below the thermosphere and holds various gases, with decreasing concentrations as altitude increases.

Is the stratosphere in the homosphere or the heterosphere?

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.


What are the differences between the homosphere and the heterosphere?

in homosphere the concentration of gases remain same and gases are mixed while in heterosphere conc. of gases is different and gases are in the form of layers.Read more: What_is_the_difference_between_homosphere_and_the_heterosphere


What is the atmosphere layer in which gases do not maintain a uniform composition?

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.


What gases make up the heterospher?

The heterosphere is made up of different layers containing various gases. The composition can vary, but generally, the heterosphere consists of hydrogen, helium, nitrogen, oxygen, and other trace gases like argon and carbon dioxide. These gases are distributed unevenly in different layers based on their molecular weight.


What is the difference between homosphere and the heterosphere?

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.
