Which gases may mainly occur as light gases in the exosphere?
Answer and explanation
Correct answer: Hydrogen and helium
At the great heights of the exosphere, the lightest gases are relatively more important because heavier gases are less abundant and gravity causes gases to become increasingly sparse. Hydrogen and helium are the principal examples used in school descriptions. Carbon dioxide, water vapour, dust, smoke, nitrogen, and soil are not the expected pair for this outer atmospheric region.
