If a warm ocean current flows near a coast what effect is possible?

Correct answer: Coastal temperature may rise relatively

The direct answer is C: coastal temperature may rise relatively. Ocean currents carry heat from one region to another. A warm current transfers warmer water and heat toward a nearby coast, so the coastal air and temperature may become higher than they would otherwise be, though the exact effect depends on winds, season and other controls. Option C is correct because it says “may” and “relatively,” which is scientifically careful. Option A is wrong because a warm current does not make a coast always ice-covered; freezing is associated with very cold conditions. Option B is wrong because a current does not make the sea disappear. Option D is wrong because latitude is the angular distance from the Equator and is fixed by location; a current cannot make it zero. The key chain is warm current → heat transfer → possible relative warming near the coast. Memory cue: warm current warms nearby coasts; cold current tends to cool them.
