What are the benefits of wind for humans and what are the hazards of wind to humans?

Benefits of wind for humans:

When you're tired from the day, a cool breeze can soothe your fatigue.

When it's hot, the breeze blows and we feel comfortable.

The wind also helped us to dry our wet clothes.

Wind can generate electricity, and the wind can also blow kites into the sky.

The wind, in turn, pushes the windmill to spin and makes the sailboat speed up ......

Humans cannot live without the wind. If there is no wind, plants that rely on the wind to spread pollen cannot spread and reproduce; The polluted atmosphere is not diluted; Sailboats will not be able to sail on the water; The air on which human beings depend for survival will be like a "pool of stagnant water", polluted; Many creatures will struggle to survive.

Hazards of wind to humans:

The wind can overturn ships on the sea, blow away fertile soil, and knock down crops, trees, and houses.

The benefits of wind: When you are tired from the day, a cool breeze blowing in your face can relieve your fatigue.

When it's hot, the breeze blows and we feel comfortable.

The wind also helped us to dry our wet clothes. The wind can blow the sails and propel the ship forward.

Wind can also help plants spread pollen. The wind can also generate electricity, and the wind can blow kites into the sky.

1. Wind causes air movement to bring precipitation and snowfall.

2. Ocean currents are caused by a wide range of air movements.

Exercise to balance the heat distribution of seawater.

3. Regulate the temperature differences in the atmosphere and place the equatorial region.

The updraft of the thermal air diffuses towards the poles.

4. Pollination and propagation of wind-borne plants.

5. Wind power generation.

6. Air purification, polluted air diffusion.

1. Spread pathogens and spread plant diseases. High-altitude wind is the meteorological condition for long-distance migration of pests such as armyworms, rice planthoppers, rice leaf rollers, and locusts.

2. The strong wind will affect the yield due to mechanical abrasion of leaves, lodging of crops, broken trees, and falling flowers and fruits.

3. Strong winds also cause soil erosion and sand dunes to move, destroying farmland. Blind reclamation in arid areas will lead to desertification of the land by wind. High winds and snowstorms in pastoral areas can scatter herds and exacerbate frost damage.

4. Wind sometimes causes a small number of people to disappear, mainly destroying houses, vehicles, ships, trees, crops, communication facilities, power facilities, etc.

1. The wind will blow tidbits and help the plants spread. We understand that many plants spread by the power of the wind. The so-called "peach blossom elm pod has no talent, only the solution is to make snow fly all over the sky." "It's by the power of the wind.

2. The wind can blow the sailboat and help people walk. Especially in ancient times, transportation work mainly relied on boats, and Li Bai had in "Difficult to Travel" that "there will be times when the wind and waves will be long, and the clouds will sail into the sea." Verses.

3. The wind will blow away the dark clouds and bring us sunshine. When the clouds block the sun, it is the wind that drives them away, allowing the sun to shine again on the earth.

4. The ancients used windmills to water crops.

5. In the hot summer, the wind brings us coolness.

6. At this moment, people have also learned to use wind energy generators to generate electricity. It's non-polluting, clean energy, and renewable.

7. The wind blows the clouds, which can promote the exchange of dry and cold and warm and humid air, so that a wide range of . Heat and water vapor are mixed and balanced, regulating the temperature and humidity of the air. This is what the ancients said, "clouds cause rain, and dew turns into frost".

Wind energy transports clouds and rain to distant places, allowing the water cycle on Earth to be completed. Most parts of the country are affected by the monsoon. In summer, the warm and humid air currents blowing from the ocean bring abundant rainfall.

8. The northeast trade winds stir up a strong flow of seawater, forming a warm current, which brings a warm and humid climate to the coastal land through which it flows.

1. If we say that this year is a good year, it is generally described as "wind and rain". Because of the action of the wind, the atmospheric circulation is formed, which brings abundant precipitation, which not only directly moistens all things, but also brings surface runoff, forms rivers, irrigates the land, makes crops thrive, harvests grain, cotton and linen, and enables people to have food and clothing.

Second, the wind can make people sail away, in ancient times, Zheng He went to the Western Ocean, and Europeans discovered the New World, all of them used sailboats, which were powered by the wind. In China, before the invention of the steam engine, most of the ships that sailed were powered by the wind, and went to the sea to fish and transport goods.

3. Wind flows from high pressure to low pressure, so the extractive industry has a special ventilation system, without ventilation, it is impossible to transport air, all kinds of toxic and harmful gases can not be eliminated, and fresh air cannot enter, which is also the role of wind.

Causes:

Wind is a phenomenon of air movement on Earth, generally caused by the heat of solar radiation. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the air on the surface of the earth is heated and expands lightly and rises.

When the hot air rises, the cold air at a low temperature flows laterally, and the rising air gradually cools and becomes heavier and falls, and the air heats up to rise due to the high surface temperature, and this air flow is called wind.

When the accumulated water vapor (cloud) forms water, the volume shrinks, and the surrounding water vapor comes to replenish it, forming wind. The wind on the earth is related to the water source, and the wind is produced by the expansion and contraction of water and water vapor. The wind blows from the sea to the land, or the land blows to the sea.

1. Wind is a natural energy source, which can promote the exchange of dry and cold and warm and moist air. Long ago, humans learned to build windmills that were blown by the wind to pump water and process food, and are now used to generate electricity.

2. Wind energy can mix and balance a wide range of heat and water vapor, and adjust the temperature and humidity of the air; It can send clouds and rain to distant places, so that the water cycle on the earth can be completed.

3. Wind plays an important role in improving the farmland environment in the agricultural squadron. We know that the movement of air forms the wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air. Conditions are created for the growth of crops.

4. Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce.

5. But the wind also often brings disasters to human beings, such as storms, typhoons, and hurricanes, which will flood farmland, collapse houses, and cut off water and electricity. Tornadoes can destroy large areas of buildings, leaving them in shambles.

6. Moreover, the wind will also bring up sand and dust, form sandstorms, endanger the human body, and drive the desert to move and cause desert.

1. Benefits to agricultural production: Wind is one of the environmental factors of agricultural production. Moderate wind speed plays an important role in improving the environmental conditions of farmland. The heat exchange near the surface, evapotranspiration of farmland and the transport of carbon dioxide and oxygen in the air are accelerated or strengthened with the increase of wind speed.

2. Help plants pollinate and reproduce: Wind can spread plant pollen and seeds, helping plants pollinate and reproduce. The monsoon prevails in China, which is beneficial for crop growth.

3. Wind energy as a new energy source: Wind energy is a widely distributed and inexhaustible energy source. In the Inner Mongolia Plateau, the Northeast Plateau, the southeast coast and the inland mountains, there are abundant wind energy resources that can be used as energy resources.
