Flexi Says: Of all the volcanoes in the world, very few are erupting at any given time. Scientists question whether a volcano that is not erupting will ever erupt again and then describe it as active, dormant, or extinct. Active: Currently erupting or showing signs of erupting soon. Dormant: No current activity, but has erupted recently. Extinct: No activity for some time; will probably not erupt again. Examples of dormant volcanoes include Mount Kilimanjaro in Africa and Mount Fuji in Japan while an example of extinct volcanoes is Mount Thielsen in USA.
