The local and global effects of volcanic eruptions include toxic ash 'rain', that pollutes streams, rivers, and chemically alters ground water sources as well as soil.

What percentage of global volcanic eruptions take place in sea bed?
total 40% of global volcanic eruptions take place on sea bed. that is why many of the small islands are formed
Why do volcanoes errupt due to global warming?
Volcanic eruptions are not caused by anything related to climate.
Can a volcanic eruption drop the global temperature?
Yes, volcanic eruptions can drop global temperature. The release of sulfur dioxide into the stratospheric aerosol layer causes chemical reactions that reflect the sun's rays away from Earth. It has even been studied as a possible (if not controversial) model for counteracting the effects of global warming from carbon dioxide buildup.
What phenomenons would be considered an observable indication of global warming?
Yes, there are natural phenomenons that produce global warning but most of them are very slow processes that they can't be noticed. Volcanic eruptions is one of such phenomenons, but to increase global warming at present rate with volcanic eruptions, earth need more active volcanoes.
How does dust from volcanoes link to global warming?
Volcanic eruptions can reduce global warming for a short time by blocking and reflecting the sun's heat with their dust and ash.

How does plate tectonics affect global warming?
it affect global warming due to emissions sent from volcanic eruptions and multiple other emissions `
How does dust from volcanoes link to global warming?
Volcanic eruptions can reduce global warming for a short time by blocking and reflecting the sun's heat with their dust and ash.
What causes masive climate changes?
global warming, massive (vei8) volcanic eruptions & meterorite hits (ask the dinosaurs)
How do large scale volcanic eruptions cause global temperature decrease?
ash arises making the sun blocked and the temperatures be effected
Do volcanic eruptions increase global warming?
Usually not. The amount of carbon dioxide emitted by volcanoes is very small compared to our emissions from the burning of fossil fuels. In fact, the dust and ash emitted by volcanic eruptions often shields the earth from the sun's rays for days and sometimes weeks, bringing a cooling effect.
How has the Earth's climate changed over time?
Earth's climate has changed due to ice ages, volcanic eruptions, asteroid impacts, the Sun's cycle, and global warming.
How can volcanic eruptions contribute to global climate change?
Volcanic eruptions can enhance global warming by adding some carbon dioxide (CO2) to the atmosphere.Volcanic eruptions can reduce global warming for a short time by blocking and reflecting the sun's heat with their ash.i think u should ask your teacherbecause of all the dust left in the air after the eruption, the temperatures drop because all that dust bocks the sun.it decreases the earth's temperatureooh i loove these kind of questions.. it decreases the earths temperature because when it erupts it releases ashes into the air. -- so than the ashes block out the son, decreasing the UV (ultra violent) rays from the sun from touching the earth.
When a volcano erupts can it block the sun?
Yes. Large explosive volcanic eruptions can produce enormouys ash clouds that can turn day as dark as night in areas around the volcano. Ash and gas from such eruptions can filter out enough sunlight to reuduce global temperatures.
