Why can rainfall increase when a coastal area has a mountain barrier nearby?

Answer and explanation

Correct answer: Moist sea air rises after striking the mountain

The direct answer is option A: moist sea air rises after striking the mountain. Coastal air receives water vapour from the sea. Step by step: the sea warms and supplies moisture to the moving air; winds carry this moist air toward land; a mountain barrier blocks its horizontal movement; the air is forced upward along the slope; rising air expands and cools; cooling causes water vapour to condense into clouds; clouds may then produce relief or orographic rainfall on the windward side. Option A correctly gives this complete chain. Option B is wrong because sea waves do not normally stop rainfall; they are not the main cause of mountain rainfall. Option C is wrong because a mountain does not make air disappear; it changes the air's path and forces it upward. Option D is wrong because coastal air often contains considerable moisture precisely because it is near the sea. The leeward side may become drier in a rain-shadow area, but that does not cancel the rainfall on the windward side. Memory cue: moist air plus mountain lift gives cooling, clouds and rain.
