Question

explain the occurrence of land breezes and sea breezes

Answer 1

In the day, when the sun is up, the land heats up very quickly and the air above it warms up a lot more than the air over the water. The warm air over the land is less dense and begins to rise. Low pressure is created.The air pressure over the water is higher with cold dense air, which moves to occupy the space created over the land. The cool air that comes along is called a sea breeze.

In the night, the reverse happens. The land quickly loses its’ heat whiles the water retains its’ warmth. This means the air over the water is warmer, less dense and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.

Answer 2

Both land breeze and sea breeze are affected by the temperature

Land breeze:

• A land breeze blows from land to sea at the night, and the land is cooler than the sea because of the difference in temperature.
• The air above the sea becomes less dense over time.
• The cooler air from the land moves in to replace the warm air.

Sea breeze:

• The sea breeze blows during the day, but because the land is warmer than the sea, it causes the land to heat up faster than the sea.
• The air on land becomes less dense (warmer) and rises, so the cooler air over the sea (denser) flows in to take the place of the warm air, causing a sea breeze.
