How do large scale volcanic eruptions cause global temperature decrease?
ash arises making the sun blocked and the temperatures be effected
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.
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
Describe local and global effects of volcanic eruptions?
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.
Can volcanic activity decrease global temperatures?
Yes. Explosive volcanic eruptions release sulfur dioxide into the atmopshere. This gas forms tiny droplets of sulfuric acid in the upper atmosphere, which reflect some of the sun's warming rays back into space.

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.
Can earth be cooled by volcanic eruptions?
Yes. Large explosive eruptions can release large amounts of sulfur dioxide. This gas forms tiny droplets of sulfuric acid in the upper atmosphere, which reflect a portion of the sun's light back into space and reduce global temperatures.
Why do volcanoes errupt due to global warming?
Volcanic eruptions are not caused by anything related to climate.
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 does plate tectonics affect global warming?
it affect global warming due to emissions sent from volcanic eruptions and multiple other emissions `
What is volcanic ash and how does it affect worldwide climate patterns?
Volcanic Ash is the material produced from volcanic eruptions which is ejected into the atmosphere. It is normally comprised of carbon and mineral based debris, rock strata, granite, basault dust etc. This material sits in the atmosphere and actually absorbs thermal energy and also helps to shield the earth from sunlight, as a result it lowers global temperatures slightly when there is a large eruption akin to either Krakatoa or St helens. It is thought volvanic eruptions could actually slow down global warming.
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.
