Which layer contains the largest mass of the atmosphere?
Answer and explanation
Correct answer: Troposphere
The governing concept is the vertical distribution of atmospheric mass under gravity. Gravity compresses the air most strongly near Earth’s surface, so pressure and density are greatest in the lowest layer. Consequently, the troposphere contains roughly three-quarters of the atmosphere’s total mass, making option A correct. The mesosphere, thermosphere, and exosphere are progressively higher and contain much thinner, less massive air.
