this all has to do with where the volcano is located. some volcanos are located in places where ther is more activity underneath, and other have not so much activity. the more activity, the more violently the volcano will erupt.
A volcano erupts quietly if its magma is low in silica. Low-silica magma has low viscosity and flows easily.
Because the pressure of magma is different in each volcano.
Because of the amount and pressure of gases in the magma tubes of a volcano.
In geography we learn bout volcanoes n apparently ma teacher said Mt Etna is a quiet volcano
Hope this helped
=) Kris y8 XD
A shield volcano is a quiet eruption that flows like a sheet, rather that a violent eruption.
because they do, stupid.
A Shield Volcano.
Very varied. Some volcanoes erupt almost continuously, others erupt at periods of some hundreds of years.
It depends on the volcano. Some volcanoes can erupt very often, while others will only erupt once every hundred years.
Volcanoes are only destructive to people and property when they erupt. Volcanoes can lie dormant for decades before they erupt. The Hawaiian Islands were all formed from eruptions of volcanoes in the ocean.
They're all different. Some erupt multiple times a day, some are dead (never erupt) :)
Volcanoes take thousands of years to make by tectonic plates converging and diverging, the necessary pressure for some volcanoes to erupt takes hundreds to thousands of years to build up. Some volcanoes are constantly eruptive, these eruptions having little explosive properties, other volcanoes don't erupt for thousands of years.
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.
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
Some do. Most volcanoes will erupt more frequently than that, but some do go 1000 years or more between eruptions.
As many as it wants. Some volcanoes erupt often, some infrequently

Yes. Many volcanoes erupt more than once during their "lifetime." Some volcanoes are hundreds of thousands, even millions of yeas old and erupt periodically.
the preasure of the magma is not putting that much preasur
because they were formed under the sea so when they erupt the can form tsunamis
no all the volcanoes do not erupt.there are three types of volcanoes extinct,average and active. no because there are dome mountains that do not erupt and they are full of lava and they will erupt in more or less than 300 years.

No. Many volcanoes are dormant or inactive.
