1, making food: wind can accelerate the loss of water, such as air-drying meat, air-drying fruit meat. Raisins from Xinjiang are typical air-dried food.

2, blow-drying clothes: wind can accelerate the evaporation of water on clothes, speeding up the loss of water, so that clothes dry faster.

3, wind power generation and watering: the wind can drive the windmill blades to rotate, and then through the speed booster to increase the speed of rotation, to prompt the generator to generate electricity. Wind power is non-polluting, clean energy, and renewable. Ancient people also used windmills to water their crops.

4, to help fruit trees, crops blossom and bear fruit: the wind can blow away pollen, so that fruit trees, crops fertilized blossom and bear fruit.

Expanded:

Wind is a natural phenomenon caused by the flow of air, which is induced by radiant heat from the sun. The sun's rays shine on the earth's surface, causing the surface temperature to rise, and the air on the surface is heated and lightened by the expansion and rises.

After the hot air rises, cold air with low temperature flows horizontally, and the rising air gradually cools and becomes heavier and falls down, and because of the higher temperature of the earth's surface will heat up the air so that it rises, and the flow of this air produces the wind.

From a scientific point of view, wind often refers to the horizontal component of air movement, including the direction and size, that is, the wind direction and wind speed; but for flight, but also includes the vertical component of the movement, that is, the so-called vertical or elevation of the air flow. High winds can move objects and object (mass of matter) direction. The wind is very fast.
