Answer:
On the basis of periodicity of eruption, volcanoes are classified into three types: (i) active volcanoes, (ii) dormant volcanoes, and (iii) extinct volcanoes.
Explanation:
(i) Active Volcanoes:
Volcanoes, from whose vents there is constant emission of volcanic materials such as, lava, ashes, lapilli, pumice and gases etc. are called active volcanaoes. Some of the active volcanoes are continually in eruption, while in other cases the eruptions are intermittent.
(ii) Dormant Volcanoes:
There are certain volcanoes which do not show any sign of volcanic activity for a long time. They are in a state of slumber. They appear to be extinct.
(iii) Extinct Volcanoes:
This is an extreme case when a volcano permanently stops its volcanic activity. Even though the cone and its crater may still be present, it no longer emits steam
