(d) Explain which mode of heat transfer
causes sea breezes and land breezes.
Answers
Answer:
Sea breezes and land breezes occurs due to convection mode.
Answer:
Convection causes sea breeze and land breeze. Heat transfer through fluids takes place by the process of convection.
Sea breeze: It is the wind that blows from the sea or the oceans towards the land. It develops during day time when the land heats up quickly. Also, the water heats up slowly as compared to land due to which water in the sea and oceans is relatively cooler than land. Therefore, the air near the land becomes hot and rises up and the cold air from sea takes the place of hot air. The hot air than moves toward the sea to complete the cycle.
Land breeze: It is the wind that blows from 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.
