Question

State whether true or false:
Convection currents are set up giving rise to sea breezes.
A. True.
B. False.

Answer 1

Hint: Convection Currents affect the weather all over the Earth. We know that convection currents can affect even the smallest amount of weather, like wind. An example of this occurs when a land mass is adjacent to a body of water. When a land mass is adjacent to a body of water during the day it causes a sea breeze.

Complete answer:
Yes, the given statement is true that convection current is set up which gives rise to sea breezes.
Convection currents are the result of differential heating. Less dense (lighter) warm materials rise while heavier (more dense) cool materials sink. It is the movement that creates a circulation pattern known as conventional current in the atmosphere, water and mantle of earth.

Hence the given statement is true.

So, the correct answer is “Option A”.

Additional Information:
A Land Breeze can also happen when a land mass and a body of water is adjacent to one another. A land breeze happens at night when the water heats up faster than the land, which means the air over the water is warmer and less dense than the air over the land. When this is in place the warmer less dense air over the water rises and the colder less dense air replaces it.

Note:
Basically a Sea Breeze happens when the land heats up faster than the water which means the air over the land is warmer land less dense than the air over the water. Since the air is less dense it rises, then the colder more dense air from the water replaces it and causes an onshore breeze. This movement of air from land towards the ocean along the coast is called Land-Breeze. Actually, in both the cases, there is a circulation of air. In sea-breeze, it is towards the land close to the surface but in the upper regions.
