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.

How can volcanoes errupt under water?
The tectonic plates shifting is what causes an underwater volcano to erupt. Plate shifting is also the cause of tsunamis and earthquakes.
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 are the two ways volcanoes erupt?
there lots of diffrent ways slow steady fast .
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 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?

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.
