Question

Wind current is generated due to:
A. Uneven heating between equator and poles.
B. change in atmospheric pressure.
C. Thunderstorm
D. cyclone

Answer 1

Hint: Wind currents happening to the surface waters of oceans and seas are a result of the action of wind on the surface of the water. Wind currents are arising due to the combined influences of the forces of friction, viscosity of turbulence, pressure gradient, deflecting force of the earth's rotation, and so on.

Complete step by step answer:
First of all let us look at what a wind current is. Actually moving air is known as wind. Wind current is the air that moves in a river like flow in a particular direction. In which thermal updrafts are mild currents due to warm air rising. Wind currents are produced due to the non-uniform heating of the Earth. That means uneven heating at the equator and the poles. This warm air rises and the making up of cooler air from the regions with the 0-30 degrees latitude belt on either side of the equator moves in. This is how wind currents are being generated. Current winds bring up air from one type of climate to the other. Suppose let warm winds that travel above water tend to collect moisture as they travel, then the water vapour in the air gets to be condensed as it moves into colder climates. This is why temperate coastal areas are frequently receiving heavy rainfalls.

So, the correct answer is “Option A”.

Note: Wind is the air that is moving horizontally along the earth's surface. The temperature and humidity get varied in the wind system. But air current is the vertical or nearly vertical movement of air. This is the difference between these two.
