Which Atmosphere term is correctly associated with weather or climate role: “many meteors burn up in it”, and also with “the layer above the stratosphere”?

Correct Answer: Option D — Mesosphere. Mesosphere is correct because it is many meteors burn up in it. Mesosphere is also associated with the layer above the stratosphere. A further identifying fact is that Mesosphere is it contains some of the coldest atmospheric temperatures. Another useful fact is that Mesosphere is associated with many meteors burn up in it. Why the other options are incorrect: Option A — Thermosphere: It is auroras occur mainly in this region and is associated with a very thin upper atmospheric layer; those are the identifying facts of Thermosphere. Option B — Exosphere: It is light gases such as hydrogen and helium dominate and is associated with the outermost atmospheric region; those are the identifying facts of Exosphere. Option C — Ozone layer: It is its depletion increases surface UV exposure and is associated with a region of enhanced ozone concentration; those are the identifying facts of Ozone layer. Exam Takeaway: Link Mesosphere with “many meteors burn up in it” and “the layer above the stratosphere” for quick revision.
