Question Q.5Briefly discuss and explain impactsGS1GS1
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
Volcanoes are the landforms formed due to release of lava (molten magma)

Main Body
Volcanoes are the landforms formed due to release of lava (molten magma) & other debris (dyaclast) from inside of the earth through a vent. (eg)Hawaiian Volcanes. Role of plate tectonic theory: (1) Divergent platesOcean-ocean divergence leader to formation of ridges. (2) Convergent platesOcean-continent (eg) Andes, Rockies St.Helena. Volcanoes islands as Hawaii, (continues)
Two plate come towards each other. Subduction of dense plate (Oceanic) & melting of plateeruption of magma. Impacts of volcanoes: (1) Acid rainrelease of nitrogen & sulphur oxides by SO Sulphates (2) Ashescovers nearby areas (crop loses, discast soil) (3) Formation of igneous rocks (lava) (4) Landformscomposite volcanoes, Flood basalt (ex- Deccan Traps), black soil. Volcanoes as a landform are mainly found around Pacific ring of fire as explained by Plate tectonics.
