If gases are very rare in a layer and light particles spread toward space, which layer is it?
Answer and explanation
Correct answer: Exosphere
The governing clue is the gradual transition from the atmosphere into outer space. The exosphere is the highest atmospheric layer, where particles are extremely far apart and some light atoms can move into space because collisions are infrequent. This matches both clues in the question, so option C is correct. The troposphere and stratosphere are much denser, while the mesosphere is not the outermost layer.
