Rainwater, an indispensable part of the earth's water cycle, is almost the supply of terrestrial plants far away from rivers.
The only way to get fresh water.
2.
Rainwater can irrigate crops and is beneficial to afforestation.
3.
Rain can reduce dust in the air and lower the temperature.
4.
Rainwater is beneficial to reservoir water storage, groundwater recharge and river water replenishment, as well as power generation and shipping.
5.
Rain can isolate the noisy world, create a quiet environment, hypnotize and wash the streets.
Question 2: What are the benefits of rain? Rain is the most common thing in nature, but rain in different seasons has different characteristics.
The rumbling thunder is like beating gongs and drums, and the rain column is like an arrow leaving the string, attacking the earth crazily.
1. can purify the air.
2. Rainwater seeps into the land and becomes groundwater.
3. Basic conditions of ecological cycle.
Question 3: What benefits will rain bring to people? Rainwater can irrigate crops, help plants to plant trees, reduce dust in the air, replenish river water and help power generation and shipping.
Question 4: What are the advantages of rainy days? 1) Climate has a significant impact on people's health and mood: We know that climate has an impact on some diseases, such as arthritis and heart disease. The climate can also make people feel irritable. Therefore, people should master these laws, give full play to their subjective initiative, exercise restraint when they are upset, and pay attention to protecting the sick.
(2) The influence of humidity on people: rainy days will make people feel depressed. Of course, this bad mood is partly due to social factors. However, research shows that more people will get depression on humid days; The low air pressure before it rains on cloudy days will make school-age children fidget.
(3) the influence of sunshine on people: sunshine is really good for mood, especially in winter. On sunny days, people will be more willing to help others and abide by social order. But high temperature and sunny days in summer are exceptions.
(4) What is the relationship between dry and hot wind and bad mood? In many countries, such as the United States, Switzerland and Israel, this dry and hot air will increase mental disorders. People will be inefficient, unresponsive and easily angry. We think this is because this wind reduces negative ions in the air, which is good for people. They can improve people's brain function and improve their mood. Positron has the opposite effect Some surveys show that people will be extremely active and excited before a rainstorm. We think this is related to the change of charged particles in the air. Lightning can increase negative ions in the atmosphere and make people feel happy.
(5) Influence of atmospheric pressure: The change of atmospheric pressure will cause many health problems. When the atmospheric pressure changes, the cavity in the human body expands, such as: the decrease of atmospheric pressure will cause sinus problems, leading to sinusitis and sinus expansion; The increase of air pressure has a great influence on human joints; A drop in air pressure can also make people restless.
(6) Influence of extremely cold and hot climate on heart disease patients: Extreme temperature, especially extremely cold weather, will make people's cardiovascular system overworked. More people will die of heart disease in winter than in other seasons. Because when the temperature is very low, blood flows into the body from the skin, and the heart should beat the blood hard to keep the body warm. Therefore, some strenuous activities in cold climate will increase the burden on the heart. Another death peak of heart patients is in summer. Summer heat intensifies the beating of the heart, makes people sweat more and raises blood pressure. Extreme cold and hot weather will overload people's immune system, thus weakening people's resistance. Hot weather makes people vulnerable to infectious diseases such as malaria. Colds and respiratory infections are common in winter, because low temperature weakens the body's resistance.
(7) Who are particularly sensitive to climate? A few people are particularly sensitive to climate, but they are also sensitive to environmental problems such as noise pollution. Comparatively speaking, the elderly are more sensitive to climate than young people, because their cardiovascular system is weak. The weight is the same. Fat people are uncomfortable in hot weather, and thin people are uncomfortable in cold weather. In the experiment, men and women have almost the same response to climate.
(8) Influence of air conditioners and dryers: These devices create an artificial indoor climate to avoid the influence of extremely cold, extremely hot and extremely humid climate, which is very good. However, air conditioning will absorb negative ions in the air, which will have adverse effects on brain function and mood. Air conditioning will produce a lot of cations, and staying in this air for eight hours will cause headaches. We used to think that the headache in the room was caused by carbon monoxide, but now it is proved that the increase of cations is also one of the reasons.
In the experiment, using an ion generator to generate negative ions can improve the mood of office workers. Negative ion air is good for people's mood. One of the reasons why people like to travel to mountainous areas is that there are a lot of negative ions in the air there.
(9) The influence of climate on sleep: It is difficult for people who are afraid of heat to fall asleep in summer. Sleep research experiments show that when the air pressure is higher or lower than normal, people will feel sleepy, and the reasons remain to be studied.
(10) What is the best climate for physical and mental health? The temperature is about 2 1℃, and it is better to have some breeze and not too strong sunshine.
The human body is quasi-constant temperature. In order to keep the body temperature constant, it is necessary to constantly discharge the heat generated by metabolism to the outside world, so that the skin temperature is higher than the outside temperature. When the temperature is close to the skin temperature, the heat dissipation is not smooth, which will cause discomfort. At this time, the human body will increase perspiration and release heat in the form of evaporation and heat dissipation. According to the research, when the general temperature is 30-32℃ and the relative humidity is 85%, or when the temperature is 38℃ and the relative humidity is 50%, or when the temperature is 40℃ and the relative humidity is about 30%, people's body temperature regulation ability will be difficult, resulting in heatstroke.

Question 5: What benefits does rain bring to people? profit
Irrigation of crops is conducive to afforestation, reservoir storage, reducing dust in the air, lowering the temperature, replenishing groundwater, replenishing river water for power generation and shipping, creating a romantic atmosphere for lovers, creating a peaceful environment for isolating the world, hypnotizing, washing streets and retaining distinguished guests.
Question 6: What are the benefits of rain? Why does it always rain? The benefits of rainwater to human beings are: replenishing water, irrigating farmland, purifying air, lowering temperature, forming river waterfalls and making mountains and rivers beautiful.
The disadvantages of rainwater to human beings are: floods, landslides, mudslides and other natural disasters. Because the water vapor in the atmosphere is cold in the sky, it condenses into ice, then falls under the action of gravity and melts into water in mid-air.
Rain can purify dust in the air, moisten plants and promote natural water circulation.
Question 7: What benefits can rain bring to people? Rain can irrigate crops,
Is beneficial to plant afforestation,
Dust in the air can be reduced,
Replenish the river,
Conducive to power generation and shipping.
