Final answer:
Changes in air pressure cause land breezes and sea breezes. During the day, land heats up more quickly than the ocean, resulting in a sea breeze. At night, the land cools down faster than the ocean, resulting in a land breeze.
Step-by-step explanation:
Changes in air pressure cause land breezes and sea breezes. During the day, land heats up more quickly than the ocean due to the difference in heat capacities of water and land. Warmer air over the land rises, creating a region of low pressure. Cooler air over the ocean flows towards the land to fill the low-pressure area, resulting in a sea breeze. At night, the situation is reversed. The land cools down faster than the ocean, causing the air over the land to become colder. This creates a region of high pressure, and the cooler air over the land flows towards the ocean, resulting in a land breeze.
