It is what comes out of the vent of an explosively erupting volcano and may rise miles into the atmosphere.
A vent through which gas, ash, and magma erupt onto Earth's surface is called a volcano.
An eruption column is a vertical column of ash and volcanic gases rising above a volcano during an explosive eruption, while a pyroclastic flow is a fast-moving avalanche of hot rock fragments and volcanic gases that flows down the sides of a volcano at high speed. Eruption columns are visible in the sky, while pyroclastic flows move rapidly along the ground, causing devastation in their path.
Composite or stratovolcanoes are known to produce ash clouds due to their explosive eruptions caused by the buildup of gas pressure within viscous magma. These eruptions can release large amounts of ash, gas, and rock fragments into the atmosphere, creating dangerous ash clouds that can travel long distances from the volcano.
A volcano can interrupt by releasing ash, gas, and lava which can cause destruction to surrounding areas. Additionally, volcanic eruptions can lead to earthquakes and tsunamis which can further disrupt the environment and communities.
The ash rises because it is in a cloud of hot gas. This cloud is then carried by the wind.

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.

gas gets trapped doesn't it and magma or lava gets shot out
A volcano eruption occurs when magma, gas, and ash are expelled from a volcano's vent. This can lead to lava flow, ash cloud, and pyroclastic flows. Eruptions can vary in intensity and can have wide-ranging impacts on surrounding areas.
A volcano explodes when magma (what lava is called when it is underground) comes up with gas trapped in it. The gas can form bubbles in the magma that grow so quickly that it creates an explosion. The real word for this is "erupt" because not all eruptions have explosions. Sometimes the lava just oozes out from the weight of the rock pressing down on the magma.
No. Volcanic ash consists of tiny solid particles of rock and glass that get blasted out during explosive eruptions.
