What causes a volcano to erupt? Depending on the type and duration of the eruption lava and or tephra can pile up to make a volcano. What happens when volcanoes erupt? When it reaches the top, it explodes from the cone of the volcano. The pressure of the gases in the magma causes the volcano to erupt.
Science & Technology at Scientific American.com: Ask the Experts ... What causes a volcano to erupt and how do scientists predict eruptions? Bob Abram, MOLTEN ROCK, or magma, and gasses spew from the mouth of a volcano in more
Volcanic eruptions are caused by the release of pressure from molten rock (magma) beneath the Earth’s surface. This pressure builds up due to the accumulation of gases within the magma, forcing it to rise and eventually reach the surface, resulting in an eruption. The type and intensity of the eruption depend on various factors such as the composition of the magma and the presence of gas, water, and other materials.
Usually the magma clogs causing major pressure causing the volcano to explode violently or some times movement in the earths crust
Increasing lava content and pressure tectonic plates makes the volcano to erupt.

What climates do volcanoes need to be in to erupt?
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.
Where does volcanoes mostly erupt in?
they mostly erupt in Hawaii
How do cinder cone volcanos erupt?
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
What are the two ways volcanoes erupt?
Volcanoes erupt through explosive eruptions, characterized by violent ejections of rock fragments and gases; and effusive eruptions, where lava flows steadily out of the volcano.
How can erupt the volcano?
Volcanoes erupt when there is an earthquake or when there is too much pressure inside it.
What causes the volcanoes to erupt on Venus'?
No one know if there are active volcanoes on Venus. There are old ones. There is no evidence of plate motion on Venus.
Do tsunamis erupt?
No. Volcanoes erupt.
What causes volcanoes to erupt under earths surface?
mostly earthquakes or plate tectonic movement.
How many volcanoes can erupt at once?
An unlimited amount of volcanoes can erupt at once
How many volcanoes erupt yearly?
About 60 volcanoes erupt each year.
Do volcanoes erupt at the end of the year?
Volcanoes can erupt at any time of year.
What climates do volcanoes need to be in to erupt?
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.
What type of volcano does and does not erupt?
Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
Why do volcanoes effect planes?
After volcanoes erupt, a huge cloud of ash rises above it. This ash cloud causes problems for aeroplanes in mid flight.
Are volcanoes considered volcanoes when they erupt?
Yes, they are.
What makes composite volcanoes to erupt?
Ash and Gas make composite volcanoes erupt i believe
Where does volcanoes mostly erupt in?
they mostly erupt in Hawaii
