Which Atmosphere term is correctly associated with location: “located near the Intertropical Convergence Zone”, and also with “surface winds are often light and variable”?

Correct Answer: Option B — Doldrums. Doldrums is correct because it is located near the Intertropical Convergence Zone. Doldrums is also associated with surface winds are often light and variable. A further identifying fact is that Doldrums is surface winds are often light and variable. Another useful fact is that Doldrums is associated with rising moist air produces frequent convection and rainfall. Why the other options are incorrect: Option A — Troposphere: It is extends from the surface to the tropopause and is associated with temperature generally decreases with height; those are the identifying facts of Troposphere. Option C — 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 D — 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. Exam Takeaway: Link Doldrums with “located near the Intertropical Convergence Zone” and “surface winds are often light and variable” for quick revision.
