Question

which one of these answer is correct ?

Q)Sea breezes are caused by...

A)	cooler air flowing offshore (toward the ocean) in the afternoon.

B)	the fact that land heats and cools more slowly than water.

C)	the fact that warmer air is denser and settles to the surface of the land.

D)onshore (toward the land) air flows that develop in the afternoon as the land heats faster than neighboring water surfaces.

Answer 1

Sea breeze occurs during the day time, when the land surface is heated faster than the neighbouring water bodies. Therefore the air above the land is warmer than the air above the water bodies. Thus warmer air rises, and cold and dense air flows from ocean to land. This makes on shore air flow during the afternoon.

So option D is most suitable answer.
