Which clue can distinguish the exosphere from the thermosphere?
Answer and explanation
Correct answer: Gradual merging into space and extremely rarefied gases
The exosphere is the outermost atmospheric region. Its particles are extremely far apart, collisions are rare, and the atmosphere gradually fades into outer space rather than ending at a sharp surface. The thermosphere below it is also thin and hot, but it remains a more conventionally defined atmospheric layer. Hence option B gives the best distinguishing clue. Dense clouds, maximum water vapour, and monsoon activity are tropospheric features, not exospheric ones.
