During the day, land gets heated up much faster than the water in the sea .As the land becomes hot , it heats the air above it. this hot air rises up and the cool air from the sea blows towards the land to take its place . this wind that blows from the sea towards the land during the day is called the sea breeze . At night , the land cools down much faster than the sea which , in turn., cools the air above the land . The air above is still warmer . This warm air rises up and the cool air from the land rushes towards the sea to take its place .This wind that blows from the land towards the sea at night is called the land breeze .
