What is the state of solar activity in recent years, and this is an example of the impact on our pro

Sunspots are produced in the photosphere with a period of 11 years, which will cause abnormal climate, especially precipitation, and cause drought and flood disasters.

David Hathaway, a solar physicist at NASA's Marshall Space Flight Center, said, "The 24th solar cycle will reach its peak in 2010 or 2011." "Therefore, the abnormal precipitation in many parts of China and the drought and flood disasters are likely to be due to the relationship between sunspots.

Flares occur in the chromosphere and can cause abnormalities in radio shortwave communications.

A magnetic storm is an electromagnetic disturbance that causes a strong disturbance in the Earth's magnetic field, preventing the compass from indicating the direction correctly.

The solar wind is produced in the coronal layer, and when the solar wind reaches the high altitude of the earth, it produces a beautiful aurora.

According to the British "Daily Telegraph", on July 27, a violent solar flare erupted triggered a "solar storm" on a larger area of the sun's surface, erupting a large number of charged particles from the earth hundreds of millions of kilometers away, forming a strong solar wind, and the sunspots under the flare are the size of the earth. NASA scientists** said that the stream of charged particles generated by the "solar storm" will "hit" the Earth on August 3, impacting the Earth's magnetic field and producing intense aurora at the Earth's poles, which will be a very spectacular and gorgeous sight. However, experts warn that if the "solar storm" is too violent, it will destroy the Earth's satellites and cause widespread power and communication system disruptions around the world.

Let's be a student of the high school attached to Yangda University. I also searched for a long time and couldn't find anything.

Now I'm going to provide some content that I hope will help you.

The year 1999 was the 23rd cycle of solar activity, and according to the theory that the average period is about 11 years, 2009-2010 should be the 24th cycle. So during this time, solar activity is going to be more frequent.

You'll find the rest yourself. But what is this to grab a question, even if you can't write it, it's okay.

It's original. Pure hand-hitting. There is no merit and hard work.

The solar wind produces auroras.

Flares create magnetic storms that affect shortwave communications on Earth.

In the United States, Bell Labs developed practical silicon solar cells, laying the foundation for the large-scale application of photovoltaic power generation.

In the year of the French National Research Center, a 50 kW solar furnace was built in the eastern part of the Pyrenees.

In Florida, USA, the world's first ammonia-water absorption air conditioning system heated by a flat plate collector was built, with a refrigeration capacity of 5 tons. In 1961, a Stirling engine with quartz windows was introduced.

But at present, we mainly use carbon sun, which can use its heat to make a solar cooker, or use the sun's energy to convert into electricity, that is, solar panels, etc., which are all okay. In the future, it is said that it will be possible to make solar sails using the pressure of the sun.

The sun is a planet in the universe full of huge energy, and people can do a lot of work with the sun in real life, such as our common solar energy.

In real life, we use the sun to do a lot of beneficial things, like solar batteries, solar water heaters, and some solar street lights.

We use solar energy in real life, mainly using solar power generation, now there are a lot of street lights, are solar street lights, of course, we also see solar energy to boil hot water in many places, that is, solar water heaters.

In life, there was an invention and brought a lot of a relatively good way of socializing, so that the way of exercise can make people have a lot.

In our real life, people are using solar energy as sincerity, solar energy shines brightly, and these inventions have been common in our lives and have played an important role, so the use of solar energy is getting higher and higher.

In real life, people have used the sun to make inventions, and it will be okay in the future. The workers and peasants who used the sun and the solar energy took showers and baths. Sunlight is also irradiated.

Conduct various experiments. Use the sun's rays to loosen the mattress and dry the quilt. The lives of ordinary people are inseparable from the sun.

All of our people have made use of the sun for what inventions, in the future we will try to clean up this sure people of the sun, solar power generation, as well as sun exposure and solar radiation, and planting.

In real life, people use the sun to carry out solar lamps, solar power generation, etc., and in the future, people may create many things that people will use.

Nowadays, we use the sun to do a lot of applications, such as solar lighting or solar power generation, which has a very great effect and role in our daily life.

It is not too strong, there are more fragrant solar power generation, and solar water heaters are all used to convert some energy by using sunlight.

There are many things that use solar energy to generate electricity, use solar energy for heating, and use solar energy in life. For example, a solar-powered replica spaceship.

In real life, you have a lot of inventions using the sun, and other people close the circuit, it's too difficult, water heaters, solar energy, water eggs.

You can use the sun to be a poet a lot, and use solar energy to solve the energy problem in life.

Because the sun, the sun can generate electricity, oops, the sun can do solar power.

There are a lot of solar energy things, such as practicing solar power generation, solar street lights, and even solar energy to cook, etc.

In real life, what kind of homes do people use the sun for? Can you have a solar water heater? There is also solar power generation, all related, all of them are the sun of karma, and all things have to turn on the sun, if there is no sun, this person, food will not grow!

For example, solar water heaters, as well as solar flashlights, they all need to use sunlight to ** light or heat energy.

I think it's a little too far, and you can still keep using new energy, keep driving.

It can be said that we are inseparable from the sun, for example, almost everything on the earth is inseparable from the sun, for example, green can be said to be inseparable from the sun, for example, almost everything on the earth is inseparable from the sun, for example, almost everything on the earth is inseparable from the sun, for example, almost everything on the earth is inseparable from the sun, for example, green plants and animals and other plants have to be separated from the sun.

For example, the vegetables we eat have no photosynthesis, they can no longer grow, and eventually there are no green plants, and human beings are almost unable to survive.

Solar activity, magnetic field, electric field, disease, health.

The earth in which human beings live is provided by the most basic energy provided by the sun, and the activities of the sun profoundly affect human health. Solar activity refers to the active phenomena on the surface of the sun and in the atmosphere, such as sunspots, flares, coronal material eruptions, etc., and the activity has a certain periodicity. At the peak of solar activity, the number of sunspots increases, and flares erupt frequently.

These activities produce large amounts of energetic particles and high-intensity radio electricity, which disturb the Earth's magnetic and electric fields as the solar wind arrives on Earth. The earth itself.

It's a huge magnet, including humans.

All living things are under the influence of the geomagnetic field.

Under multiplication. There is a microscopic in the human cell.

type magnets, arranged in strips, countless throughout the body.

Biological miniature magnets make up the whole body intrinsic.

Biomagnetic field. Scientific studies have shown that the magnetic field is strong.

fluctuations in degrees will affect to varying degrees.

Blood pressure, nerves, meridians, and cells in the human body.

and various organs. In the same way, the earth is one.

Huge electric field world: from the ionosphere to the ground, there is an ultra-high voltage of 360,000 volts.

The strength of the electric field near the ground can also be achieved.

About 130 volts per meter. Atmospheric current and electric field.

It is extremely important for plant growth and development, and can also affect the human nervous system.

The above conclusions are obtained through experiments and reality.

to the seal. The experimental results showed that the regenerative reproduction ability of bacteria decreased by 15 times when they lived under low magnetic field for 72 hours. The rats were placed in an environment completely shielded from the geomagnetic field, and the activity of enzymes in the body changed strongly.

A large part of the "space syndrome" that astronauts who live far from Earth suffer from in space is caused by the absence of magnetic fields. The greater the potential difference between the plant and the atmosphere, the faster the plant's photosynthesis will proceed; If people work or live near tens of thousands of volts of equipment or high-voltage power lines for a long time, they will be easily agitated and fatigued, and the brain will be inefficient and suffer from other diseases.

One. Affecting the Earth's magnetic field is that the magnetic needle does not indicate the direction correctly.

Two. Disrupts the ionosphere and affects radio shortwave communications.

Three. It causes abnormal climate, affects the daily life and health of human beings, etc.

1.The ionosphere is disturbed, affecting radio shortwave communications.

2.The Earth's magnetic field is affected, and the phenomenon of "magnetic explosion" occurs.

3.Auroras appear in polar regions.

4.Induce natural disasters, such as floods and droughts.

Answer: A sunspot is a sign of the strength of solar activity. When sunspots intensify, solar activity such as flares also increases. Select item A.

d Chinese name: Aurora English name: aurora Definition 1:

The phenomenon of colored luminescence due to the explosion or ionization of the upper atmosphere gas by the solar particle stream often occurs at high latitudes. Discipline: Atmospheric Science (first-level discipline) ; Atmospheric Physics (Secondary Discipline) Definition 2:

Colored luminescence in the atmosphere of a planet's high magnetic latitude. A stream of extraneous high-energy charged particles enters the two magnetic poles along the planet's intrinsic magnetic field and collides with gas molecules and atoms in the upper atmosphere to form an aurora. Discipline:

Astronomy (first-level discipline) ; Solar System (Secondary Discipline).

Magnetic storms are when the surface of the sun is active, especially during the sunspot maximum, the number of flash bursts on the surface of the sun will also increase, and the flash bursts will emit X-rays, ultraviolet rays, visible light, and high-energy protons and electron beams. The electric currents formed by the charged particles (protons, electrons) in it impinge on the earth's magnetic field, causing what is known as a magnetic storm in short-wave communications. Magnetic storms will enhance the ionosphere in the atmosphere, and will also make the aurora in the polar region particularly gorgeous, in addition, it will also produce noise to cover up the normal signal of communication, and even interrupt communication, and may also make high-voltage wires produce instantaneous ultra-high voltage, resulting in power interruption, and will also cause harm to aircraft.

a. The solar atmosphere changes frequently, sometimes even drastically, and these changes are collectively referred to as solar activity, so they do not conform to the topic;

b. Sunspots occur in the photosphere, and there is a certain correlation between sunspots and annual precipitation, so it does not meet the topic.

c. The flare is the most intense reflection of solar activity, and it is easy to rise and cause magnetic storms and interfere with shortwave hall communication when it erupts, so it is correct;

d. The solar wind is a stream of high-energy charged particles, and its burst period is about 11 years, so it does not meet the meaning of the topic
