Volcanic eruptions bring heat with them, so why does the local temperature drop after they erupt

The theory of plates is the doctrine of calamity to the country and the people.

In chemical experiments, chemical changes occur in substances, heat energy and kinetic energy appear, chemical changes occur in the interior of the earth, and chemical changes in the interior of the earth form huge heat and kinetic energy, resulting in volcanic eruptions. This is the most scientific answer.

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

2. Destroying the environment. The combination of volcanic ash and heavy rainfall from volcanic eruptions can create mudslides that can wash away roads, bridges, and inundate nearby villages and cities, leaving countless people homeless.

3. Triggering a tsunami. An undersea volcanic eruption can trigger a tsunami that threatens people living near the coastline.

4. Trigger**. The lava flows from terrestrial volcanic eruptions can incinerate everything, not only changing the terrain and landform, but also causing ** and other secondary disasters.

Sphere of Effect:

The damage caused by a tsunami is mainly in the environment near the volcano (which expands as the eruption becomes more powerful), and the damage and impact are generally one-time and not very long. But the damage to the environment from volcanic eruptions is much longer lasting than that of a tsunami.

Volcanoes emit magma and pyroclastics, volcanic gases, etc. Magma generally does not flow too far, the temperature of magma can reach 900 to 1,004, and almost no animals and plants in nature can resist such high temperatures, so everywhere the magma goes, it will be invaded by high temperatures, and no grass will grow. Volcanic gases are gases such as water vapor, sulfur dioxide, and nitrogen.

Sulphur dioxide causes acid rain, which can erode buildings, flora and fauna, and also pollute water sources.

Volcano, one of the common landmark forms on the earth, is due to the movement of the earth's continental plates, the plates in the plate junction zone are pressed against each other, causing the nearby rocks to melt into magma due to the strong extrusion force Magma rises, that is, volcanic eruptions, and then the mountains formed in the cooling area are called volcanoes. It is divided into active volcanoes, extinct volcanoes. An active volcano is a volcano that can continue to erupt magma, while an extinct volcano does not have this characteristic, so an extinct volcano is more stable and safe than an active volcano.

Volcanic eruptions, as a unique geological phenomenon, are one of the external manifestations of the earth's crustal movement. Volcanic eruptions are also a manifestation of the release of heat from the Earth's interior, which is the release of magma and other materials from the volcano in a short period of time. Because magma contains various volatile substances, especially sulfides, sulfur dioxide in the air will form aerosols, and the influence of volcanic ash will greatly weaken the solar radiation near the volcano, which will lead to a decrease in temperature.

Volcanic eruptions have a variety of effects. Not only do we think there are many harms, but there are also many good things that will cause adverse effects such as global warming. Volcanoes are often rich in geothermal resources near volcanoes, and hot springs can form.

Iceland is a country rich in geothermal resources, which is really convenient for heating, and it can also generate geothermal electricity. In addition, volcanic eruptions can also know the land, and the eruption of magma from an undersea volcano over the course of a month will cool down into rock, and land will be formed over a long period of time.

Finally, volcanic eruptions produce large amounts of sulfides, greenhouse gases, and particulate matter. Sulfur dioxide, which is the main component of volcanic ash, is formed by sulfides, and a large amount of volcanic ash will exacerbate the greenhouse effect on the one hand, and on the other hand, volcanic ash will block solar radiation, resulting in a decrease in solar radiation on the surface and a decrease in surface temperature. The end result of the two is that the temperature in the area of the eruption will drop for a certain period of time.

So, volcanic eruptions bring more than just a drop in temperature.

The most powerful and spectacular volcanic eruptions often occur in subduction zones. The volcanoes here can erupt again after hundreds of years of silence, and when they do, they are particularly powerful. Such volcanic eruptions often bring world destruction to humanity.

Affect the global climate, destroy the environment, and regain life.

The temperature of magma is very high when the volcano erupts, which can melt the rock, magnesium oxide has a melting point of 2900 degrees Celsius, the melting point of sand is 1610 degrees Celsius, and the melting point of aluminum oxide is 2034 degrees Celsius. The temperature of magma at different pressures also varies greatly, for example, it will reach 3000 under the mantle, and the temperature will increase towards the center of the earth.

The magma that overflowed the surface was like freshly baked molten steel, fiery red and red. It has been determined that the temperature of magma is generally between 900-1200 and can reach up to 1300. Wherever it flows is a sea of fire, which looks like a fiery red iron stream from a distance, and when cooled and solidified, it forms various volcanic lavas, such as basalt, andesite, rhyolite, etc.

It is because the magma shot out by Li Jian's draft will have a lot of particulate matter in it, and when it enters the atmosphere, it will affect the sun's radiation, and eventually lead to a decrease in temperature.

This is because volcanic eruptions cause local atmospheric circulation systems, which also affect ozone in the stratosphere, which causes global temperatures to drop.

This is because these magma contain a lot of harmful substances that block solar radiation, which is why the temperature drops.

This is because the magma contains a large number of harmful substances that deny solar radiation, which is why the temperature drops.

Volcanic plague bai

Harm. There are 10 major natural disasters in the world, among which are volcanoes, which are ranked sixth in DAO, and the largest recorded volcanic disaster in the world is the eruption of Mount Tambora in Indonesia, which killed 92,000 people. Therefore, the loss of human life and property caused by the eruption is very serious.

Not much else, ** headlines are flying all over the sky, and the influence is known to the whole world.

One of the most dangerous natural forces on Earth, volcanic eruptions have a huge impact on the planet.
