When a volcano erupts explosively, some of the molten rock is ejected in the form of small particles. These cool to form tiny pieces of volcanic glass. Clouds of volcanic ash either race down the sides of a volcano in avalanches called pyroclastic flows, or fall to earth like snow from tall eruption plumes. In either form volcanic ash can be dangerous. Pyroclastic flows are extremely hot, burning almost everithing in their paths. Falling ash has had time to cool, but still prsents hazards. It is very dense and can cause roofs to collapse. It clogs engines and interferes with electical equipment. It can damage the lungs if inhaled. Volcanic ash can also mix with water from rain or melting glaciers to form deadly mudflows called lahars.

What is an ash cloud from a volcano?
An ash cloud is something which comes out of the volcano
Is an ash fall a volcano?
No. An ash fall is not a volcano; it is a product of some volcanic erputions.
What causes volcanes to form?
Volcano's form at boundaries between two tectonic plates. Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface it erupts to form lava flows and ash deposits. Ash deposits result from more explosive activity and lava flows usually are associated with quieter activity. Anyway, once you have piled up lava and/or ash around the vent, you have a young volcano. After many many more eruptions you have a big volcano that is constructed of the ash and lava products of these eruptions.
What is the name of the volcano that has caused the ash cloud?
Eyjafjallajoekull volcano
Can you prevent the ash cloud from a volcano eruption when ice is concerned?
No. Ice does not create an ash cloud when a volcano erupts. You cannot prevent the formation of an ash cloud.

What is supervolcanoes?
A Supervolcano is a volcano characterized by the large area it affects. A supervolcano is generally accepted to be a volcano that discharges ash, lava, or pumis deposits that spread over 240 or more cubic miles from its center. The Indonesian Toba is an example of a supervolcano.

What type of volcano is a composite volcano?
Mt. Vesuvius in Italy, Mt. Hood in Oregon and Mt. saint Helen's
Which volcano hazard can be dangerous to passing sir planes due to its fine, abrasive quality?
Volcano ash hazard can be dangerous.
What is volcano rock?
A volcano rock is rock formed from ash or lava erupted from a volcano.
Can ash from a volcano break glass?
If the amount of ash is great enough.
What is a small particle blown out of a volcano?
Volcanic ash.
What does vent volcanic ash mean?
Ash that comes form a volcano.
