Volcanic eruptions pollute the air and what

I saw it in the encyclopedia, but it's not complete...

Volcanic eruption is a peculiar geological phenomenon that is a manifestation of the movement of the earth's crust and one of the most intense manifestations of the earth's internal thermal energy on the surface. It is the release of ejecta such as magma from a crater to the surface in a short period of time. Due to the large amount of volatile components in the magma, coupled with the confining pressure of the overlying rock layer, these volatiles are dissolved in the magma and cannot overflow, and when the magma rises close to the surface, the pressure decreases, and the volatiles are released sharply, thus forming a volcanic eruption.

Impact:1Affecting the global climate Volcanic eruptions emit large amounts of ash and volcanic gases, which have a great impact on the climate.

Because in this case, dim daylight and storms and even mud rain can plague the local population for months. When volcanic ash and volcanic gases are ejected into the air, they are dispersed by the wind over long distances. This volcanic material can block out the sun, causing temperatures to drop.

In addition, they filter out certain wavelengths of light, making the sun and moon appear to be a halo or tinge of exotic colors, especially at sunrise and sunset.

2.Damage to the environment The volcanic eruption spews large amounts of ash and torrential rains combine to create mudslides that can wash away roads, bridges, and inundate nearby villages and cities, leaving countless people homeless. The mud from dirt and rock debris can flood entire cities.

3.There are also benefits to reviving the impact of volcanic eruptions on the natural landscape. Land is the world's most precious resource, as it produces a variety of plants to support all things.

If an eruption could cover farmland with less than 20 centimeters of ash, it would be a blessing for farmers, because the ash is rich in nutrients that make the land more fertile.

Dust pollution, the formation of acid rain (oxides of nitrogen, sulfur, etc.). Contamination of water bodies and soil.

Sulfur dioxide! Volcanic ash! Thermal pollution, mixed with a lot of toxic pollution! Don't know, please refer to the relevant **.

What are the dangers to human beings after volcanic eruptions, there are many examples in some areas of the earth where volcanoes erupt frequently a long time ago.

Due to geographical location and topography, the probability of volcanic eruptions in China is relatively small, but Russia, which has friendly diplomatic relations with our country, the situation is more severe, for example, every once in a while, it is in a highly frequent state, you must know that volcanic eruptions are difficult to natural disasters, the harm to human beings is almost fatal, but what is the impact on the atmosphere, let's take a look at the answer.

Volcanic ash is the material that has the greatest impact on the atmosphere during volcanic eruptions, such as mountains, especially volcanoes that erupt in a short period of time, and the volcanic ash produced at this time will react with gases such as SO2, and once it is in a gassol state, the "parasol effect" will directly affect global climate change. In addition, volcanic dust will drift and disperse with the wind, for example, it will form a volcanic dust curtain in the sky, which will affect the transparency of the atmosphere, and then will have a strong reflection and scattering effect on solar radiation, and eventually lead to a significant decrease in the temperature of most of the surrounding areas.

Impacts of volcanoes on the environment:

In addition to the above-mentioned impact on the atmosphere, the impact on the ecological environment cannot be ignored, such as the direct impact of the Huozao Mountain activity on the ecological environment, which is to pollute the environment, destroy buildings, and endanger organisms. Take, for example, the tallest active volcano on Earth, Tuphangato. Almost every second, 2,300 kilograms of water vapor and a large amount of acidic gas escape, which also causes the valley to be full of smoke and steam, and countless dry cracks in the ground, releasing toxic sulphides.

It is important to know that sulfides will cause extremely serious harm to humans and organisms in the vicinity.

Summary. Dear, I am glad to answer for you that the impact of volcanic eruptions on the environment is affecting the global climate. Volcanic eruptions emit large amounts of ash and volcanic gases, which have a great impact on the climate.

Destruction of the environment. The combination of volcanic ash and rain from volcanic eruptions can create mudslides that can wash away roads and bridges, inundate nearby villages and cities, and leave countless people homeless.

Dear, I'm glad to bend rock to answer for you, the impact of volcanic eruptions on the environment is affecting the global climate. The large amount of buried volcanic ash and volcanic gases ejected during volcanic eruptions has a great impact on the climate. Destruction of the environment.

The combination of volcanic ash and rain from volcanic eruptions can create mudslides that can wash away roads and bridges, inundate nearby villages and cities, and leave countless people homeless.

Volcanoes are a common side-silver landform formed by the accumulation of molten material from the ground and the solid detritus carrying it from the surface. 100-150 km below the earth's crust, there is a liquid zone in which there are molten silicate remnants containing gaseous volatile components at high temperatures and pressures, known as magma. Once it washes out of the surface of the earth from a weak part of the earth's crust, it forms a volcano.
