Question Q.5Briefly discussGS1GS1
Briefly discuss the role of plate tectonics theory in explaining the location of volcanoes. Also, explain the multifarious impacts of volcanoes on the surrounding regions.
Introduction
Plate tectonics is a scientific theory which explains the origin & formation of volcanoes based on the movement of Tectonic plates

Main Body
Role of plate tectonics theory in explaining location of volcanoes:
1Convergent boundaries lead to plate formation of volcanoes
Ex - Eastern Island, India
Mt Fuji, Japan
2Divergent boundaries lead to formation of volcanoes
Ex - Mt Helena in mid oceanic ridge
3Transform boundaries do not form volcanoes but lead to earthquakes
Multifarious impact of volcanoes:
1Volcanic eruptions destroy economic and social infrastructure and cause wide spread deaths
Ex - Volcano eruption in Pompeii while volcano 2019
2Cause pollution through emission of CO2, SO2 and also cool the atmosphere
3Lead to formation of volcanic fertile soil
Ex - Deccan traps in India
4Lead to formation of landforms like volcanic islands
Though plate tectonics is the most modern theory it is yet to explain the formation of intra plate volcano activities like those in Hawaii and Iceland.
