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:
Conclusion
Understanding volcano and reducing danger to life should be foremost priority.

Diagram
Two diagrams present: (1) World plate map showing North America, Eurasian, Africa, South Atlantic, Antarctic plates and major plate boundaries; (2) Convergent boundary diagram showing lighter plate and heavy plate interaction
- Uses diagrams effectively to explain plate tectonics
- Clear explanation of plate composition and movement
- Links plate tectonics directly to volcano location
- Mentions specific boundaries (Circumscific, Pacific)
