Land and sea breezes:

Land and sea breezes are the result of convection. On a hot day, the temperature of the land increases more quickly than the sea. It is because the specific heat of the land increases more quickly than the sea. It is because the specific heat of land is much smaller as compared to water. The air above land gets hot and rises. Cold air from the sea begins to move towards the land it is called the sea breeze.

At night, the land cools faster than the sea. Therefore, the air above the sea is warmer, and rises and the cold air from the land begin to move towards the sea it is called the land breeze.
