* During the night, the land cools down faster than the water. This is because water has a higher heat capacity, meaning it takes more energy to raise its temperature.

* Cooler air is denser, so the air over the land becomes denser than the air over the water.

* Denser air sinks, creating higher air pressure over the land.

* The pressure difference between the land and the water causes the air to flow from the land towards the water, creating a land breeze.

Think of it as a natural convection current, like a warm air balloon rising and cool air sinking. The land is like the "balloon" in this case, cooling down and sinking, while the water is like the surrounding air that the balloon is rising into.
