Question Q.5Briefly discuss and explainGS1GS1

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. (10 marks, 150 words)

Introduction

Plate tectonics theory stipulate. Earth composed of two major and several minor plates and ocean continent part of crust. All geophysical phenomena arise of movement of these plates.

Main Body

Volcano formation: Volcanoes are primarily located at zone of ocean-ocean convergence where heavier ocean plate subduct under light oceanic ridge. These areas are primarily located along Circumscific plate boundary (along Pacific).

Volcanoes are also located at site of formation of new ocean crust along mid oceanic ridge.

Destructive Impact of Volcano:

1Loss of Life - Humans, Animals, crushes in Mt Vesuvius and Etna.

2Destruction of Critical Infrastructure: Roads, factories, Health, Education, Infrastructure.

3Loss of agricultural lands, emission of heat near fertile soil.
