Iceland s volcanoes are influenced by China, what is the reason for Iceland s volcanoes

The time when acid rain appeared in our country: In the 80s of the last century (after 1980), acid rain appeared in our country. It mainly occurs in Chongqing, Guiyang and Liuzhou, representing Sichuan-Guizhou and Liangguang (Guangdong and Guangxi), with an area of 1.7 million square kilometers.

Since the beginning of the Industrial Revolution (the sixties of the eighteenth century; That is, after 1760), the large use of industrial raw materials by human beings led to the frequent occurrence of acid rain, which was only 350 years ago, and there was no "once in 750 years"!

Iceland's volcanoes are tens of thousands of kilometers away from China, contain countless high mountains, experience many different air currents, and do not see the warm currents of Europe passing through the Himalayas. In "See You or Leave", didn't Ge You say that if you open a 50-kilometer-diameter hole in the Himalayas, the warm current of Europe will not be a snow-capped ......mountainListen to the meaning of the upstairs, those ashes don't go anywhere, just float to China? It's just strange people, sending strange messages ......

The news hasn't been reminded yet.,It means that it's probably not as critical as the landlord said.。

The ash will drift towards the North Pole, not south.

Uh, thanks for the reminder, it's really not clear.

Well, I'm going to go to the Northeast in a few days. What a coincidence

Fake, now the official has also spoken.

The impact of air transport is significant.

1. Iceland is located at the extinction boundary of the American plate and the Pacific plate, where the earth's crust is active, magmatic activity is frequent, and magma erupts to form volcanoes.

2. Iceland is located in the mid-ocean ridge volcanic belt, which is volcanically active.

3. The mantle of Iceland is close to the surface, and the magma of the mantle is easy to flow out.

4. Iceland has high geothermal energy and is prone to molten bodies and volcanoes.

5. Almost the entire country of Iceland is on volcanic rocks, most of the land cannot be cultivated, and there are more than 200 volcanoes in Iceland, including more than 30 active volcanoes.

On October 2, 1996 (August 20, 1996 in the lunar calendar), a glacial volcano erupted in Iceland, causing the river to swell.

On October 2, 1996, an active volcano in Vatnajökull in East Iceland began to erupt, melting the ice and causing the river to swell.

The volcanic ash spewed out by the volcano is 5,000 meters high and is drifting northward, and the glacial fissure caused by the Huoqi section of the mountain is 10 kilometers long. Residents of northeastern Iceland were told to stay in their homes and not go out.

Natural disasters in 1996 included storms, floods, volcanic eruptions, forest fires, droughts, high temperatures, severe cold, landslides and avalanches, the most serious of which was the catastrophic floods along the Yangtze River in China in summer, the largest flood in the world in 150 years.

The worst storms occurred in the northeastern United States, causing severe economic damage; The worst fires were the steppe fires in Mongolia in April, which spread more than 100,000 square kilometres.

The eruption of the volcano in Iceland is caused by the melting of the glaciers that originally covered the volcano, which causes the pressure to become smaller, so that the magma force cannot be suppressed. In March and April 2010, the South Icelandic volcano erupted twice in quick succession, causing flooding caused by the melting of the magma ice sheet and the large amounts of gas and ash released by the eruption, which had long-term effects on air transport, climate and human health.

The volcanic ash from the volcano also spreads in the atmosphere, causing cloudy skies in Iceland, the United Kingdom, Germany, Poland and many other countries. As of the 16th, many routes in western Europe have been suspended. This has postponed the plans of many leaders to go to Poland to mourn the death of Poland's Kaczynski in a plane crash a few days ago.

Poland therefore postponed Kaczynski's funeral.

Because of the postponement of flights, rail and road transportation is booming. In addition, volcanic ash also has a certain impact on some patients with respiratory diseases, but fortunately, most of the volcanic ash is subtle and less harmful. Effect of volcanic ash on flights:

It will turn off the engine of the aircraft, because civil aircraft fly mostly on clouds, where lightning and hurricanes are relatively rare, and it is suitable for flying; It is also a place of volcanic ash.

When an aircraft flies into the clouds, the ash will be trapped in the engine and cool, causing the engine to stop. As the plane flew to an altitude of about 4,000 meters, the ash melted and fell off, and the engine started working again.

The large amount of volcanic ash ejected by the volcano can cause serious harm to the respiratory system and eyes of the human body. In addition, if the dust of volcanic ash is inhaled into the engine of the aircraft, it will adhere to the engine equipment, which will affect the normal operation of the machinery and reduce the safety factor of the aircraft. In addition to affecting aviation safety, volcanic ash can also cause great damage to buildings.

Because Iceland's volcanic ash contains a lot of water vapor in it, it is dense and adhesive, and it can easily adhere to buildings and power lines, and in severe cases, it may cause buildings to collapse and so on. If volcanic ash enters the stratosphere, it will reflect sunlight back into the atmosphere, which will also affect the light.

Scholar Peter Simmons recently said in an interview with the United States**: "The falling volcanic ash may cause many problems. "For example, at the beginning of the 19th century, the eruption of Mount Tambora in Indonesia ejected volcanic ash brought the toxic gas sulfur dioxide, which met the water vapor in the air to form sulfuric acid mist, which flowed into the stratosphere and blocked all sunlight, resulting in 1816 becoming a year without sunlight.

On April 19, Iceland's Eyjafjallajökull erupted, and the volcano was already turning from ash to lava.

Iceland is not only cold and snowy, but also the most volcanically active region in the world. There are more than 200 volcanoes on the island, including about 30 active volcanoes, and there are more than 150 volcanic eruptions recorded in history. In today's Iceland, 11% of the ground is covered by volcanic lava.

For this reason, Iceland is also known as the "island of ice and fire". Not only are there volcanoes on the island, but volcanic eruptions are also frequent on the nearby seabed. In 1963, a mountain erupted in the ocean near Iceland, forming a small island, which the Icelanders gave it the name of Setsey Volcanic Island.

There are two main reasons for volcanic activity in Iceland. One is that Iceland is a geographically hot spot, and the magma in the mantle is closer to the surface than most of the earth. Another reason is that Iceland is located on the Eurasian and American plates of the Mid-Atlantic Ridge, which are squeezed by each other.

These two reasons make Iceland's crust fragile and conducive to volcanic eruptions.

1. Because Iceland is a geographically hot spot, the magma in the mantle is closer to the surface than most places on Earth.

2. Iceland is located on the Eurasian plate and the American plate of the Mid-Atlantic Ridge, which are squeezed by each other. These two reasons make Iceland's crust fragile and conducive to volcanic eruptions.

A volcano is a raised mound or mountain formed by the accumulation of solid debris, lava flows, or dome-shaped ejecta around its vent. A volcanic eruption is a pipe from the Earth's mantle or lithosphere to the surface, where most of the material accumulates near the crater and some is carried high by the atmosphere and dispersed hundreds or thousands of kilometers away.

The formation of volcanoes is a series of physicochemical processes. The main thing is that the large amount of radioactive material present in the interior of the earth, decays in its natural state, producing a large amount of heat. This heat cannot be dissipated to the ground, and the temperature continues to rise until the rock melts, forming a state of hot melting in the Earth's interior.

Once this magma breaks through the earth's crust and erupts out of the ground, volcanoes are formed.
