How do volcanoes affect the earth's atmosphere?

Answer 1

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.

Answer 2

There are many ways in which a volcanic eruption affects the atmosphere. The temperature near the volcano will change dramatically. There are many gases from the volcanic eruption that are released into the atmosphere as well.

Answer 3

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.

Answer 4

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.

Answer 5

Huge plumes of gas, ash and steam is shot into the air. If the eruption is big enough, the resulting ash cloud can spread over much of the planet and have a short-term cooling affect as it blocks sunlight.

Answer 6

they affect the atmosphere because two young ladies, Megan Wing and Hayleigh Smith raped the moon.

Answer 7

When a giant war starts underground a mans penis goes crazy and then explodes, therefore exploding the crust, which creates a volcano this then effects the atmosphere greatly.

Answer 8

It can add more oxygen to the atmosphere then needed.

Answer 9

yes, volcanoes react with the oxygen in the earths atmosphere and forms thick black clouds in th sky.
