ज्वालामुखिता में शामिल प्रक्रियाओं पर चर्चा कीजिए। यादा के उष्ण ज्वालामुखी क्षेत्र और उत्तरी सर्पिण विवर्तनिक विखंडन पर प्रकाश डालिए। Discuss the processes involved in volcanism. Highlight the major volcanic regions in the world and their associated tectonic settings.
Introduction
Volcanism refers to the process in which internal rocks come out to lava on the surface of the earth.

Main Body
Major factors leading to the volcanism are:
ii) Hot plumes - volcanic hotspots are formed when some areas are much warmer and lava flows out of them. (Eg) Yellowstone National Park USA
The major volcanic regions lie around the Ring of Fire - along the boundaries where Pacific plate meets the other land plates such as American plate, Eurasian plate. Indonesia is one of the most volcanically active country along with Philippines.
The divergent plates such as Mid-Atlantic Oceanic ridge shows some activity.

Conclusion
The volcanism offers opportunity to understand the interior of earth. They are also major source of precious natural s [materials]. Thus processes of volcanism is an important geological phenomenon.
