Why are light gas particles like hydrogen and helium important in the exosphere?
Answer and explanation
Correct answer: Because light gases are common in this upper, rarefied layer
The exosphere is the outermost, extremely rarefied region of Earth’s atmosphere. Because gravity is weak there and collisions are infrequent, the lightest gases, especially hydrogen and helium, can dominate and may gradually escape into space. They do not produce ordinary raindrops or surface fog, and ozone is mainly associated with the stratosphere. Therefore, option A is correct.
