Why can high mountain areas be cold even if they are near the sea?

Correct answer: Altitude effect can reduce temperature

The direct answer is A, Altitude effect can reduce temperature. Climate is controlled by several factors, so being near the sea does not automatically make every place warm. Step by step: a high mountain location has greater elevation above sea level; as altitude increases in the lower atmosphere, temperature generally decreases; therefore a high place may be cold even when it is geographically close to the sea. Nearness to the sea may moderate temperature, but altitude can produce a strong cooling effect. Option A is correct because it explains the relevant competing climatic control. Option B, the sea always making temperature zero, is an exaggerated and false statement; the sea moderates temperature but does not reduce every temperature to zero. Option C, latitude suddenly changing, is not necessary: a nearby mountain and nearby coast can have nearly the same latitude. Option D, wind always stopping, is false and does not explain the general cooling of high areas. Remember: several controls act together; altitude usually lowers temperature as height increases.
