There are approximately 1,500 active volcanoes on Earth. These volcanoes have erupted at least once in the last 10,000 years.
Mt. Helena once erupted, and the explosion was 20 x the explosive power of an atomic bomb.
1500
It has to do with them because the Ring of Fire is formed by plates volcanoes. Once volcanoes errupt(and aren't active anymore), they can be mountains.
The Paricutin volcano erupted only once, starting in 1943 in Mexico. It is known for being one of the few volcanoes in history to be observed from birth to extinction.

Active volcanoes: are those that erupted lava,gases ,cinder,pumice,etc in the historic pass.Eg: Mt.St.Helena Dormant volcanoes: are those which erupted in the past and are likely to erupt again after remeaining inactive for fairly long periods. These are "sleeping" volcanoes which may become active once again. eg: Mt.vesuvius.Extinct volcanoes: are those volcanoes which were active in the remote geological periods. Eg: Mt.Kenya

An Active volcano is one that has erupted at least once in the past 15,20years.An Extinct volcano has not erupted within the past 15,20 years.A Dormant volcano is an Active volcano that is not currently erupting but can erupt anytime.
Volcanoes melt the rock and eventually erupt. Once it erupted the rock starts to setal and cool into a certain type of rock
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.
There are more active volcanoes in the ring of fire because the ring of fire has the most moving plates. When plates move they cause volcanic eruptions. Places farther away or not in the ring of fire will not erupt as often or will only erupt once before extinction.
Once molten rock has erupted and solidified, it is called lava.
An unlimited amount of volcanoes can erupt at once
