Volcanoes

Volcanoes are causes when molten rock flows out on to the earth’s surface through fissures that are caused due to the movement of plates.

Based on the chances of eruption the volcanoes are classified in to three

1) Active volcanoes2) Extinct volcanoes3) Dormant volcanoes

ACTIVE VOLCANOESVolcanoes that frequently erupt Eg. Mount Etna

Mount Fujiyama

VOLCANO ERUPTION

Extinct volcanoes

Volcanoes that active at a time. But with not exrupt again.

Eg. Kilimanjaro in Africa

Dormant Volcanoes

Those that have erupted earlier and not acive in the recent past. But can become active

Eg. Vesuvius in Italy.
