How can the effect of altitude appear among places located on the same latitude?

Correct answer: The higher place can be relatively cooler

Direct answer: Option C is correct. At the same latitude, places receive broadly similar solar-angle effects, but altitude can still make their temperatures different. Air pressure decreases with height and, in the lower atmosphere, temperature generally falls as altitude increases. Thus a high town may be cooler than a low town at nearly the same latitude, although actual weather also depends on relief, winds, cloud, season and other controls. Option A is wrong because lower places are not always colder; the usual altitude pattern is the reverse. Option B is wrong because equal latitude does not make every other condition identical. Option D is wrong because altitude affects temperature and several weather conditions; it does not merely measure rainfall. Therefore C is the careful, correctly qualified statement. Memory cue: same latitude does not mean same altitude or same temperature.
