If a layer has very rare air and gradually merges with space, which layer is it?
Answer and explanation
Correct answer: Exosphere
The exosphere is the outermost atmospheric region. Its gas particles are extremely far apart, so the air is very rarefied, and there is no sharp upper boundary separating it from outer space. Option A is therefore correct. The troposphere and stratosphere are denser lower layers, while the lower mesosphere still has a defined atmospheric environment.
