Which option best describes the nature of the exosphere?
Answer and explanation
Correct answer: An outer transition region containing extremely rarefied gases
The governing concept is the structure and position of the exosphere. It is the outermost atmospheric region, where gas molecules are extremely far apart and collisions are infrequent. Its composition and gradual transition into outer space make it a very rarefied boundary region rather than a dense weather layer. Ozone concentration is associated mainly with the stratosphere, while many meteors burn in the mesosphere. Thus, option B is correct.
