Question

why does sea breeze occur only in day time and land breeze in clear evenings?​

Answer 1

Answer:

The air pressure over the water is higher with cold dense air, which moves to occupy the space created over the land. The cool air that comes along is called a sea breeze. In the night, the reverse happens. The land quickly loses its' heat whiles the water retains its' warmth.

Answer 2

Answer:

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. ... Recall that the land surface cools quicker than the water surface at night.
