The uneven heating that occurs between land and water causes land breeze and sea breeze. A gentle wind is known as the breeze. During summer, the land near the equator gets heated up faster and reaches a high temperature compared to the water in the oceans. Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air.
