Sea breeze is a coastal breeze that flows in which direction during the day?

• A. A coastal breeze moving from sea to land because the land is warmer
• B. A breeze from land to sea due to cooler land
• C. A high-altitude jet stream
• D. A mountain wave condition

Answer: (A)

During the day, the land heats up faster than the sea, causing the air over the land to rise and create a low pressure near the coast. Cooler air from the sea moves toward the land to replace this rising air, producing a breeze that blows from sea to land along the coast. This onshore flow is the daytime sea breeze. It’s not related to the high-altitude jet stream or mountain waves, which are different atmospheric phenomena. At night the pattern can reverse as the land cools, but the daytime effect is a sea-to-land flow.
