Final answer:
Sea breezes form during the day along coastlines when the air temperature on land is greater than the air temperature above the water. The breezes change direction at night, moving from the land toward the ocean.
Step-by-step explanation:
Sea breezes form during the day along coastlines and consist of cool air moving toward the shore from the ocean. This occurs when the air temperature on land is greater than the air temperature above the water. The specific heat capacities of water and sand play a role in this process. At night, the sea breezes are reversed, moving from the land toward the ocean.
