If the Sun is radiating energy during the day to the ocean and the ground at the same rate, then in which direction will the air flow?

A.
The air will flow from the land to the ocean, as the warm, light air above the ocean rises, creating a vacuum that pulls the cool, dense air from the land.


B.
The air will flow from the land to the ocean, as the cool, dense air above the land gets pulled down by gravity and spreads to the ocean.


C.
The air will flow from the ocean to the land, as the cool, dense air above the ocean gets pulled down by gravity and spreads toward land.


D.
The air will flow from the ocean to the land, as the warm, light air above the ocean is pushed toward land by the waves.

The correct answer is:

A. The air will flow from the land to the ocean, as the warm, light air above the ocean rises, creating a vacuum that pulls the cool, dense air from the land.

This describes a sea breeze, which occurs during the day as the land heats up more quickly than the ocean. The warm air over the land rises, and in response, cooler air from the ocean moves in to replace it.
