Volcanoes form when molten rock flows from fissures in the Earth's surface caused by movement of tectonic plates. Volcanoes are classified as active, extinct, or dormant based on eruption likelihood. Active volcanoes frequently erupt, like Mount Etna and Mount Fujiyama. Extinct volcanoes were once active but will not erupt again, such as Kilimanjaro. Dormant volcanoes erupted in the past but are not currently active, though they could become active again, for example Vesuvius in Italy.

PRESENTATION

3. 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.

4. Based on the chances of eruption the
volcanoes are classified in to three
1) Active volcanoes
2) Extinct volcanoes
3) Dormant volcanoes

5. ACTIVE VOLCANOES
 Volcanoes that frequently erupt
Eg. Mount Etna
Mount Fujiyama

6. VOLCANO
ERUPTION

7. Extinct volcanoes
 Volcanoes that active at a time. But with not exrupt
again.
Eg. Kilimanjaro in Africa

8. Dormant Volcanoes
 Those that have erupted earlier and not acive in the
recent past. But can become active
Eg. Vesuvius in Italy.
