Final answer:
The process of winds blowing out toward the water at night is driven by cooler air from the land moving to replace the rising warm air above the water, due to the differential cooling of land and water after sunset.
Step-by-step explanation:
Near the shore, winds tend to blow out toward the water at night due to the differences in temperature between the land and the ocean. The correct answer is A. Warm air above the water rises and is replaced by cooler air from the land. During the day, the land heats up more quickly than the water because of the lower specific heat capacity of the land. This causes the air above the land to become warmer and rise, leading to a low-pressure area. Cooler air moves in from the sea to replace the rising warm air, creating a sea breeze. At night, the process reverses because the land cools down faster than the water. The cooler, denser air over the land moves towards the warmer, less dense air over the water, generating a land breeze.
