Why does the wind change direction?

Answer 1

During the day, the sun shines on the water and land and warms them both. Since land gets warmer than water faster, it heats the air above it. As the warm air above land rises, the cold air above the water replaces the warm air. The movement of air from water to land is called sea breeze. As night falls, both the land and water begins to cool down. Once again, land cools faster than water. Now, the air above the water is warmer than the air above the land. The air above the water rises. The cooler air from the land moves to the water to replace the rising warm air. During the morning, you will feel the wind blowing to the ocean to land. At evening, you will feel the wind blowing from the land to ocean. At night, you feel the wind blowing from the ocean to land.
