Question

Classify the volcanoes based on their frequency of eruptions.

Answer 1

1. Active volcanoes: These erupt at frequent intervals. They consistently eject lava, gases, ash, and other materials. Examples include Etna in Italy and Stromboli in Sicily.
2. Dormant volcanoes: These have not erupted for a long time recently or in historic times but may erupt again at any time. They are dangerous due to this uncertainty. An example is the Barren Island volcano in the Andamans.
3. Extinct volcanoes: These have not shown any activity for about 10,000 years or more and are considered dead. They lose connection with the magma chamber. Examples are Arthur’s Seat in Edinburgh and Popa in Myanmar.
