Explain the occurrence of land breeze in coastal areas.

(N/A) During the daytime,the land heats up faster than the water. The air above the land becomes hot and rises,creating a low-pressure area. Cooler air from the sea moves towards the land to fill this space,resulting in a $sea \ breeze$.
At night,the land cools down much faster than the sea. The air above the sea remains warmer than the air above the land. This warm air above the sea rises,and the cooler air from the land moves towards the sea to replace it,which is known as a $land \ breeze$.
