Study the image. A house on a beach near the ocean. Point 1 is over the house, arrow is pointing up. Point 2 is over the ocean, with arrows pointing away from the land. Point 3 is over the ocean with the arrow pointing down. Point 4 is in the ocean with arrows pointing toward land. What do the arrows at point 3 indicate?

The arrow in point 3 indicates that warm air is cooling quickly.

.

Explanation:

Options for this question are:

Cool air is above water. Warm air is above land. Warm air is cooling quickly. Cool air is warming quickly.

The diagram is related to the movement of air masses between land and the ocean, according to their temperature (see image).

During the day, the heat from the sun warms the ground, which induces the heating of the circulating air and promotes its rise to the atmosphere (1).When the air masses go into the ocean (2), the low water temperatures -the ocean water is slow to warm- promote the cooling of the air, which descends (3). The air on the surface of the water go to the land (4).

Therefore, arrow 3 in the diagram shows how hot air, when over the ocean, cools down quickly. This dynamic of the air is one of the causes of the origin of the winds.
