What occurs to cool air over the land at night?

During the night, the land cools down more rapidly than the water, resulting in cooler air over the land. As this cooler air becomes denser, it tends to flow towards the warmer air over the water. This movement is a result of the pressure differences created by the temperature differences between the cooler land and the relatively warmer water. Therefore, the cool air over the land moves offshore towards the sea, creating a local breeze known as a land breeze. This process is part of the natural convection currents influenced by temperature differences, demonstrating the fundamental principles of convection in the atmosphere.
