A volcano erupts when pressure on the magma chamber causes the magma to rise and come out together with gas, rocks and ashes. The violence of an eruption depends on how much pressure the volcano is under before it erupts.
Volcanoes are caused to erupt when the inner core of the earth holds more pressure or heat inside it. Volcanoes are the outside source of releasing the lava and magma that the earth has inside it. When a volcano erupts it means that the earth is releasing a large amount of pressure from within.
Magma is continuously supplied from the mantle of the Earth. Shield volcanoes usually have a gentle eruption, as it contains basic lava. Acid-lava and composite volcanoes usually have a violent eruption as it contains acidic lava. The vent of the volcano might also be blocked, causing the magma to force its way out, thus causing a huge explosion.
In a more specific way, volcanoes erupt when rock releases pressure.
Volcanoes erupt when molten rock called magma rises to the surface. As the magma rises, bubbles of gas form inside it. Runny magma erupts through openings or vents in the earthβs crust before flowing onto its surface as lava. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. Volcanoes erupt when molten rock called magma rises to the surface.

It shoots out a column of magma underground and it becomes lava overground
because they get hot
deep wiht in the earth
They can erupt anytime, when magma rises from the mantle and spews out of the volcano.
It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.
An extinct volcano is one that will never erupt again.
yes a series of explosions can cause some volcano's to erupt
A dormant volcano is one that is just sleeping and it is possible to erupt again. An extinct volcano will never erupt again.

It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.

Yes. If it doesn't erupt and never has erupted then it is not a volcano.
it wont erupt anymore because it is an extinct volcano which means not able to erupt anymore
An extinct volcano is one that will never erupt again.
No, Mount Everest will not erupt because it is not a volcano.
it just does erupt
yes a series of explosions can cause some volcano's to erupt
When a volcano is active it will erupt. These volcanoes might take many years to erupt but will still erupt.
A dormant volcano is one that is just sleeping and it is possible to erupt again. An extinct volcano will never erupt again.
Buckhorn Caldera was not the last volcano to erupt. In fact, every day somewhere on the Earth, a volcano will erupt.
