Volcanic dust and ash in a moderate amount do not have a noticeable effect on global atmospheric conditions, however as evident after the 1991 Mt. Pinatubo eruption, a highly explosive eruption can cause cooling tends within the atmosphere. High amounts of ash and dust can reflect sunlight making it difficult for the light to reach the surface, another part of the eruption to consider is the amount of SO2 that is released intot he atmosphere, as it is the most efficient means of blocking sunlight from the surface. The Sulphur Dioxide binds with water molecules in the atmosphere creating a mirror effect and sending much more light back into space than ash and dust are capable of.

∙ 13y agoAs we have seen in Iceland, enough of it can ground air traffic in half the world. But in terms of the atmosphere, a particularly explosive eruption can eject enough sulfates into the upper atmosphere to start blocking out the sun, even on a global scale. This usually cools the earth for a year or two before being washed out.

This happened in the 1950s and 1960s, which kept global warming lower than it would have been. Various Clean Air acts around the world lowered air pollution and unfortunately allowed the planet to become warmer again.

A volcanic eruption can affect the atmosphere by?
adding large quantities of several gases, such as sulfur dioxide, to the atmosphere as well as volcanic ash and dust.
Dust and ash entering the atmosphere as a result of volcanic eruptions can affect earths?
Weather and climate.
What was the Krakatoa haze?
It was volcanic ash and dust cloud ejected into the upper atmosphere by the explosion of the volcano.
What is volcanic tuft made from?
The correct spelling is volcanic tuff instead of volcanic tuft. Volcanic ash that has been ejected from vents during eruption makes volcanic tuff.
How do Volcanoes effect the atmosphere and climate?
Volcanoes erupt gases that change Earth's atmosphere. The volcanic ash and clouds can affect the air and atmosphere

Weather and climate.
What was the Krakatoa haze?
It was volcanic ash and dust cloud ejected into the upper atmosphere by the explosion of the volcano.
Overall cooling of earth's climate is associated with what?
Clouds of dust and ash in the atmosphere from a huge volcanic eruption.
What is volcanic tuft made from?
The correct spelling is volcanic tuff instead of volcanic tuft. Volcanic ash that has been ejected from vents during eruption makes volcanic tuff.
How do Volcanoes effect the atmosphere and climate?
Volcanoes erupt gases that change Earth's atmosphere. The volcanic ash and clouds can affect the air and atmosphere
Why do people consider volcanic eruption as a disastrous event?
Because the ash, rock and lava devastate the area surrounding the volcano - and dust & ash can be carried for thousands of miles in the atmosphere.
How does volcanic ash in earths atmosphere effect solar radiation?
It increases the amount of solar radiation that reflect into space
Volcanic dust and ash can remain in the atmosphere for months or years causing?
Solar reflection will decrease, and temperature will decrease.
Is Lunar Dust on the moon actually volcanic ash?
No. The dust on the moon is accumulated micrometeorites.
The easiest way to distinguish between volcanic ash and volcanic dust particles is to compare their?
The easiest way to distinguish between volcanic ash and volcanic dust particles is to compare their diameter. Seismographs can be useful in predicting volcanic eruptions because they measure earthquake activity.
How does a volcano change the earth's atmosphere?
Volcanic eruptions pump out dust, ash and other aerosols. These stay in the atmosphere for about a week, usually causing a cooling effect, as they reflect the sun's rays. The amount of carbon dioxide emitted is small compared with what comes from burning fossil fuels.
