If escape of light gases in the upper atmosphere is discussed, which layer is most appropriate?
Answer and explanation
Correct answer: Exosphere
The exosphere is the outermost atmospheric layer, where gas particles are extremely far apart and collisions are infrequent. Because gravity holds the lightest particles less effectively there, hydrogen and helium can acquire enough speed to escape into space. The troposphere contains most weather, the stratosphere contains the ozone-rich region, and the mesosphere lies below the thermosphere; none is the best answer for atmospheric escape.
