As gas density decreases with height, which feature of the exosphere becomes clear?
Answer and explanation
Correct answer: Collisions between molecules become very rare
The exosphere is the outermost atmospheric region and contains extremely few gas particles. When density becomes very low, molecules travel long distances before meeting another molecule, so collisions become rare and the gas is highly tenuous. This directly supports option A. Dense clouds, maximum water vapour and permanent rainfall are features incompatible with the near-space environment of the exosphere.
