It is what comes out of the vent of an explosively erupting volcano and may rise miles into the atmosphere.

What are differences between an eruption column and pyroclastic flow?
An eruption column is a vertical plume of ash and gas produced by a volcanic eruption. A pyroclastic flow a a flow of similar material that moves down the sides of a volcano at great speed.
Did the people of Pompeii die from the gas and the heat of the volcano?
i think it was the hot ash
How does a volcano interrupt?
A volcano erupts when gases build to an inescapable high pressure. The gas pushes magma and ash through the cone of the volcano causing an eruption.
What transfers volcanic ash away from the volcano during an eruption?
The ash rises because it is in a cloud of hot gas. This cloud is then carried by the wind.
Is ash the same thing as gas from a volcano?
No. Volcanic ash consists of tiny solid particles of rock and glass that get blasted out during explosive eruptions.
What is a ash and gas cloud?
it is a cloud that comes out of a volcano when there is a eruption

What are the dangers from a volcano?
Lahars, Lava Runoff, ash can suffocate people, and poisonous gas that comes from a volcano when its erupting
What two things burst out of a volcano?
Molten rock, volcanic ash and gas

How does an ash cloud come out of a volcano?
There are two ways a volcano can produce an ash cloud. In most cases gas-rich magma rises inside the volcano. The gas is dissolved in the magma under pressure. As the magma approaches the surface the pressure decreases and the gas is released and expands rapidly, producing an explosion. The magma is blasted apart into tiny particles, which we call ash. The hot gasses then rise, taking much of the ash with them. In other gases, water inside a volcano may come in contact with magma or rocks heated by magma, causing steam explosions. These explosions pulverize some of the rock inside the volcano, during it into ash.

How is a ash formed from a volcano?
gas gets trapped doesn't it and magma or lava gets shot out

What is a vent called through which gas and ash and magma erupt onto the earth's surface?
This is known as a volcano.
Is ash the gas of lava?
No. Volcanic ash is not gas. It is made of tiny solid particles of rock or glass formed either when molten rock is fragmented or when solid rock is pulverized by explosive eruptions. Gas from a volcano is simply called volcanic gas.
