Land heats up faster during the day than water does. As the beach gets warm during the day, it heats the air above it. The warm air rises and cool air from the ocean is pulled in to replace it. So, air flows from the ocean to the land. At night, the land cools faster than the ocean. What MOST likely happens to the air at the beach at night?

• The air is still.

• The air moves along the coast.

• The air flows from the ocean to the land.

• The air flows from the land to the ocean.

• Some water stays liquid when everything else is frozen.

• When water is frozen it protects the nearby area from wind.
