Which Atmosphere term is correctly associated with key feature: “temperature rises with height because ozone absorbs ultraviolet radiation”, and also with “it is relatively stable and has little vertical mixing”?

Correct Answer: Option C — Stratosphere. Stratosphere is correct because it is temperature rises with height because ozone absorbs ultraviolet radiation. Stratosphere is also associated with it is relatively stable and has little vertical mixing. A further identifying fact is that Stratosphere is temperature rises with height because ozone absorbs ultraviolet radiation. Another useful fact is that Stratosphere is associated with it is relatively stable and has little vertical mixing. Why the other options are incorrect: Option A — Mesosphere: It is it contains some of the coldest atmospheric temperatures and is associated with many meteors burn up in it. Option B — Thermosphere: It is temperature rises greatly as high-energy radiation is absorbed and is associated with auroras occur mainly in this region. Option D — Exosphere: It is particles are extremely sparse and is associated with light gases such as hydrogen and helium dominate. Exam Takeaway: Link Stratosphere with “temperature rises with height because ozone absorbs ultraviolet radiation” and “it is relatively stable and has little vertical mixing” for quick revision.
