Question

Land and Sea breezes are basically caused by ______________.

• A. Temperature variations in summer and winter
• B. Differential heating between land and sea
• C. Convergence of warm and cold currents
• D. None of these

Answer 1

Answer: (B)

Differential heating between land and sea

Land and Sea breezes are basically caused by differential heating between land and sea.

During the day, the wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. So the pressure over water is low and high on land. So we have a land breeze blowing from land to sea.
