Which statement shows that the upper boundary of the exosphere is not a clear line?
Answer and explanation
Correct answer: It gradually merges into space
The governing concept is the gradual transition from atmosphere to outer space. In the exosphere, gas particles are extremely far apart and their density decreases progressively with altitude, so there is no sharp upper surface. Option A is therefore correct. Sea level is far below the exosphere, the exosphere lies above rather than below the troposphere, and rain clouds occur in the troposphere, not at its outer edge.
