Which statement correctly describes sea breeze general behavior?

• A. Warm air over the land rises and is replaced by moist/cool marine air
• B. Sea breezes occur only at night
• C. Sea breezes always increase temperature over land
• D. Sea breezes never move inland beyond 2 miles

Answer: (A)

The main idea is that sea breezes form when land heats up faster than the adjacent sea, causing air over the land to rise and creating a local low pressure near the coast. Cool, moist air from the sea then moves onshore to replace that rising air, producing a daytime breeze blowing from sea to land. That onshore flow brings cooler, more humid air inland, which is the hallmark of a sea breeze. This matches the statement that warm air over the land rises and is replaced by moist/cool marine air—the rising warm air over land and the inflow of cooler, marine air from the sea are exactly what drives a sea breeze. Why the other ideas don’t fit: sea breezes predominantly occur during the day when solar heating is strongest, not only at night. The arrival of cooler sea air typically cools the land surface rather than increasing its temperature. And the onshore flow can extend inland beyond a fixed distance; it isn’t limited to a tiny radius like 2 miles in all cases.
