Explain how a sea breeze is formed?

The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.

The land surface heats up faster than the water surface.therefore the air above the land is hotter versus the air above the ocean.the denser cool air over the  land is flowing offshore to replenish the buoyant warm air is called land breeze
