Sea breezes are convention currents that form part of the Earth's atmosphere and can be felt by winds. They are essential to warming up the land and oceans.


The Sun warms the soil and rocks of the geosphere and the water of the hydrosphere, but not at the same rate. Water warms more slowly as it reflects more solar radiation, while the darker colored continents absorb more solar radiation. During the day, the land warms faster than the water and the air above the land rises; over the water the air cools and falls forming a convection current and producing a sea breeze. At night, the land cools faster than the water and the air above the water rises and is replaced by the now cooler air from the land. This forms a convection current producing a land breeze.
