In general which is the cause of a land breeze

During the night time, when the temperature remains relatively low, then the land areas release heat more readily compared to the ocean. The oceans take more time to get heated up as well as to lose heat. When the temperature of the land area drops down then there prevails the cold denser air that blows towards the ocean and replaces the warm and less dense air over the ocean. This movement of cold and dense air from the land areas to the ocean is called the land breeze.
