Sea Breeze: During the day, the land heats up quickly due to the hot sun. Air over land becomes warm. Warm air is less dense thus it starts to rise.A low-pressure space is created over land. Air over water is cool and denser. High pressure is created over sea. Cool air from sea moves to occupy the space over land. Breeze flowing from the sea towards the land is called sea breeze

Land Breeze: During the night, land loses its heat quickly and becomes cold whereas water is still warm. Now warm air over sea rises up. A low-pressure space is created over sea. Cool and dense air from the land moves towards the sea to occupy the space. Breeze flowing from the land towards the sea is called land breeze.
