Which layer contains the largest part of atmospheric mass?
Answer and explanation
Correct answer: Troposphere
The troposphere is the lowest atmospheric layer and lies closest to Earth’s surface, where gravity keeps air molecules most concentrated. It contains roughly three-quarters of the atmosphere’s total mass and almost all of its water vapour, which explains why most clouds and weather occur there. Therefore option C is correct. The higher thermosphere, mesosphere, and exosphere are much more rarefied and together contain far less mass than the troposphere.
