Explain sea breeze and land breeze? [5 MARKS]
Each point: 2.5 Marks
The Land Breeze and the Sea Breeze is a common phenomenon observed in the coastal areas. As per definition, Land Breeze is the breeze that blows from land to sea, whereas the Sea Breeze blows from water/sea onto land.
1. Sea Breeze: During the day, land gets heated up faster than water, while water takes time to acquire the same temperature as there in the land. Hence, the air above the land gets warmed up and rises, while making a region of low pressure above land. Comparatively, the air above the sea is cooler and has a higher pressure. Thus, once the air above the land rises up by convection, it creates a space for the cool breeze from the sea to flow in. This is called Sea Breeze.
2. Land Breeze: The heating capacity of water is higher than that of sand. Hence, the sea water will retain heat much better as compared to the sand present at the land. During the night, the land cools down faster as compared to water while creating a high-pressure region over land and resulting in a low-pressure zone above sea water. The air above the water is comparatively warmer and rises up, thus creating space for cool wind over land to move in towards the sea. This is called Land Breeze.
