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.

a. The air is still
b. The air moves along the coast
c. The air flows from the ocean to the land
d. The air flows from the land to the ocean
d. The air flows from the land to the ocean
