What are land and sea breezes? Explain their formation.

During summer in places near the sea a breeze blows from land to sea during night which is called land breeze and during the day time a breeze blows from sea to land known as sea breeze. They are formed by the process of convection.

Sea breeze — During day time, land becomes more warmer than sea. So air above the land is warmer, less dense and rises up. Cold air from the sea blows towards the land to take its place. This is called sea breeze.

Land breeze — During night, land cools much faster than sea. So sea water is warmer than land and air above sea is also warmer. It rises up being less dense and cold wind from land blows towards sea to take its place. This is called land breeze.
