What is the main reason for very rare collisions between molecules in the exosphere?
Answer and explanation
Correct answer: Extreme rarefaction of gases
The governing concept is atmospheric density. In the exosphere, gas particles are separated by very large distances because the atmosphere is extremely rarefied. With fewer particles in a given volume, the probability of a molecule meeting another molecule becomes very small. Excess water vapour, rainfall, and ozone concentration do not explain this condition. Hence option D is correct.
