उत्तर : 2. "Specific heat"
व्याख्या :

Answer: B) Specific heat Explanation: The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water.   What is the cause of a sea breeze? The air over the land is warmed and rises, to a greater temperature than that over the sea. This produces a convection current, with cooler air flowing in from over the sea to replace that rising from the land. At night the land cools more than the sea, so the action reverses to produce a land-breeze, blowing off the land.
