Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches. ... The movement of the wind is a result of differences in air pressure over the land and the ocean. Warm air is less dense and rises, therefore cool air is more dense and sinks. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
land is a bad conductor of heat , so its upper surface rapidly heats during the day and in summer.it is also a good radiator of heat. Therefore, it cools quickly at night and in winter.
I hope it will help u dear
Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches.
During the night, water will retain more of its heat than land surfaces because water has a high heat capacity.
To add on, the temperature of the land cools quickly without the insolation from the sun.
