Explain land breeze and sea breeze?
Land being solid surface can easily absorb and release heat radiation. While sea being liquid heats up slowly and also loses this heat slowly.
During the day time, land surface being hotter, hot air from land surface rises up creating a temporary low pressure zone which drags cool air from the sea to the land. Thus, we have the sea breeze.
During the night time, the land surface is cool as it loses its heat quickly. But the sea surface is still hotter as water bodies lose heat slowly. So, hot air from sea surface rises up and cool air from the land surface moves towards the sea. Thus, we have land breeze.
land breeze and sea breeze blow due to the uneven difference of pressure.
when the land gets hotter during the day than the sea, since the hot air rises and cool air from sea blow from sea to land known as sea breeze.
similarly, the land breeze blows from land to sea at night.

A land breeze is created when the land is cooler than the water such as at night and the surface winds have to be very light. When this happens the air over the water slowly begins to rise, as the air begins to rise the air over the surface of the ocean has to be replaced, this is done by drawing the air from the land over the water, thus creating a sea breeze. Usually land breezes are light and reach only 5 to 8 knots.
A sea breeze is created when the surface of the land is heated sufficiently to start air rising. As air rises, it is replaced by air from the sea; you have now created a sea breeze. Sea breezes tend to be much stronger and can produce gusty winds as the sun can heat the land to very warm temperatures, thereby creating a significant temperature contrast to the water. Speeds of 10 to 20 knots is not uncommon for a sea breeze.
Land breeze is the wind that blows form the land towards the sea or the oceans. It develops during night time.Land cools down faster than water. Therefore, during night time, land is cooler than sea. Hence, cool air from the land blows towards the sea. This is called the land breeze.
Sea breeze is the wind that blows from the sea towards the land. It develops during day time.
