Ash flies out of the top of it and then the air is filled with a thick smoke. The ash then spreads out and forms an ash cloud. It contains greenhouse gases such as methane and carbon dioxide, which contribute to global warming. It may result in acid when rain falls from the ash clouds. It may also block out vision after ashes haze the air.
Some eruptions have put out so much toxic gas that entire cities were killed, such as Pompeii. Some eruptions have put out enough dust to affect temperatures worldwide, as Krakatoa has done more than once.
If the resulting ash cloud is large enough, the eruption can cause a short-term cooling by blocking sunlight as it spreads throughout much of the world.
Volcanoes emit about 200 million tons of carbon dioxide into the environment each year. This seems a lot, but humans emit more than 26,000 million tons yearly from burning fossil fuels.
This CO2 emission is more than counterbalanced by eruption-released particles in the stratosphere (the haze effect reflecting the sun) and this is responsible for a much larger cooling of the greenhouse effect.
Without the cooling influence of volcanic eruptions like El Chichon (1982) and Mt. Pinatubo (1991) global warming would actually be more pronounced.
a strong volcanic eruption can cause global cooling by 1-2 degree Celsius in a span of 10 years because the pyroclasts and other particles emitted by the volcano will cover up the hole in the ozone layer, thus blocking or preventing ultra-violet rays to penetrate.
Big eruptions can send large amounts of dirt and dust into the atmosphere. This can result in things like dirty rain or a blocking of the sun, causing a change of temperatures and disruption to apparent night and day and even seasons. There have been volcanic eruptions and other cataclysmic events that caused these kind of conditions.
Not all volcanoes give out the same kind of emissions. Usually the most common gas is water vapor, followed by carbon dioxide and sulfur dioxide.
Other gases include hydrogen sulfide, hydrogen chloride and hydrogen fluoride.
These gases can add to the greenhouse gases, contributing to global warming. They can also cause acid rain.
Ash from volcanoes is often a danger to jet aircraft and large eruptions of ash can alter the climate, often cooling it, because the particles reflect the sun's rays.
There are smallamount of volcanoes. They emit so2 and co2 gases.
This is where the weaknesses in the earths crust lie and it is the easiest place for lava to spew out of these weaker areas, therefore forming volcanoes
Volcanoes release gases such as sulfur dioxide and ash into the atmosphere, which can lead to temporary cooling by reflecting sunlight. However, large volcanic eruptions can also release greenhouse gases like carbon dioxide, which contribute to warming the Earth's climate in the long term. Additionally, volcanic eruptions can trigger chemical reactions that deplete the ozone layer, affecting atmospheric circulation patterns.

Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.

Heat!!
Heat!!
it dont u melt
I do not mean to sound rude or patronising but air IS the atmosphere.
The land will be flatend and plants such as trees will be crushed.
They slow the loss of heat
It is not, because the greenhouse affect causes global warming.
stars moon god chuck Norris earths gravity the sun the heat clouds other planets the atmosphere
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.
Burning fossil fuels adds carbon dioxide, a greenhouse gas, to the atmosphere. This can raise global temperatures.
