Question

State whether given statement is True or False
During the night, land cools faster than sea.
A. True
B. False

Answer 1

Hint:We are asked whether during the night, land cools faster than sea or not. To answer this, you need to know about the heat capacity of water and soil. Check how the difference in heat capacity between water and soil can affect their cooling rate.

Complete answer:
Given a statement, during the night, land cools faster than sea.During day time, the radiation from the sun heats up the land and sea. The heat capacity of water and soil are different. The heat capacity of water is more than that of soil so water absorbs heat slowly than soil. So, the sea gets heat up slower than land at day time. Therefore the air above the land is warmer than that of the sea.
Due to this temperature difference, thermal circulation is observed, that is the warmer air above the land rises up and the cooler air above the sea moves towards the land. This flow of wind from sea to land is known as sea breeze.At night, as water has more heat capacity than soil, sea cools down slower than land. So, now the air above the land is cooler and air above the sea is warmer.Therefore, due to the difference in heat capacity of water and soil, during the night land cools faster than sea.Hence, the correct answer is True.

Hence, option A is the correct answer.

Note: Here, we have discussed heat capacity, heat capacity can be defined as the amount of heat required for a substance to raise its temperature by one degree Celsius. One more important term we have discussed above is sea breeze, when wind blows from sea to land it is known as sea breeze and when wind blows from land to sea it is known as land breeze.
