What is the correct relation between air pressure and wind?

Answer and explanation

Correct answer: Wind blows due to difference in air pressure

Air pressure means the force exerted by air on a surface. When pressure is not equal in two nearby places, air begins to move. This moving air is called wind. The pressure difference is therefore the basic force that starts and helps direct wind. Air generally moves from a region of higher pressure toward a region of lower pressure. The greater the pressure difference, the stronger the push on the air, though Earth’s rotation and surface friction can change its exact path.

Thus option A is correct because it directly states that wind blows due to a difference in air pressure. Option B is wrong because pressure differences are essential to wind formation. Options C and D confuse wind with soil or rainfall; air pressure is not a device for measuring rain. The key idea is the connection between unequal pressure and moving air.
