Which Atmosphere term is correctly associated with location: “extends from the surface to the tropopause”, and also with “temperature generally decreases with height”?

Correct Answer: Option B — Troposphere. Troposphere is correct because it is extends from the surface to the tropopause. Troposphere is also associated with temperature generally decreases with height. A further identifying fact is that Troposphere is temperature generally decreases with height. Another useful fact is that Troposphere is associated with most weather phenomena occur in it. Why the other options are incorrect: Option A — Stratosphere: It is extends from the tropopause to the stratopause and is associated with temperature rises with height because ozone absorbs ultraviolet radiation; those are the identifying facts of Stratosphere. Option C — Mesosphere: It is extends to the mesopause and is associated with it contains some of the coldest atmospheric temperatures; those are the identifying facts of Mesosphere. Option D — Thermosphere: It is lies above the mesopause and is associated with temperature rises greatly as high-energy radiation is absorbed; those are the identifying facts of Thermosphere. Exam Takeaway: Link Troposphere with “extends from the surface to the tropopause” and “temperature generally decreases with height” for quick revision.
