Question

explain the main layer of gases in heterosphere​

Answer 1

Answer:

The major constituents of Earth's heterosphere are nitrogen, oxygen, helium, and hydrogen. Nitrogen and oxygen compose the lower portion of the heterosphere. In the higher levels of the heterosphere, above about 1,000 km, helium and hydrogen are the dominant species present. ... These include O+, NO+, O2+, and N2+.

Answer 2

Answer

The heterosphere is characterized by variation in composition and mean molecular weight of constituent gases. This region starts at 80–100 km above the earth and therefore closely coincides with the ionosphere and the thermosphere.

Description:-

The lower heterosphere also consists of a small area dominated by ionic species or free radicals. such as O+, NO+, O2+ , N2+ , and free electrons. This region of the atmosphere is called the ionosphere . Major constituents of Earth's heterosphere are Nitrogen, Oxygen, Helium, and Hydrogen.The chemistry in the ionosphere features numerous photodissociation reactions, light induced breaking of chemical bonds, and photoionization processes, light induced removal of electrons.
