yes,when earthqakes shakes lava gets bubbly and rises up and makes an eruption
Ash and Gas make composite volcanoes erupt i believe
they make new islands when they erupt

No. Volcanoes erupt.
About 60 volcanoes erupt each year.
An unlimited amount of volcanoes can erupt at once
Volcanoes can erupt at any time of year.
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to 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.
Volcanoes mostly erupt in the sea to make islands or big massesof land,
Yes, they are.
Did you know that composite volcanoes make up 60% of the Earths volcanoes. Composite volcanoes don't always have to erupt from the top. They can have many magma chambers and can erupt from the sides. They can be made of basalt, rhyolite and/or andesite. They erupt both ash and lava. The lava is very thick. When the time comes for the volcano to erupt they start to become very quiet. (Sneaky eh?)
