Theory of Plate Tectonics
According to the Theory of Plate Tectonics, what are the three primary types of plate boundaries based on their movement?
According to the Theory of Plate Tectonics, what are the three primary types of plate boundaries based on their movement?
Three Plate Boundaries
- Convergent Boundary: Tectonic plates move towards each other, eventually colliding (can lead to folding or subduction).
- Divergent Boundary: Tectonic plates move away from each other (creating rifts or mid-ocean ridges).
- Transform Boundary: Tectonic plates move horizontally past one another (often causing severe earthquakes).

Which modern-day landmasses were originally joined together as part of the ancient supercontinent known as 'Gondwana Land'?
The Southern Supercontinent
Before conventional currents fractured the crust, the following landmasses formed a single, massive continent:
- India
- Australia
- South Africa
- South America
- Antarctica

Land Surrounded by Water
- Definition: A landmass that is bounded by the sea on exactly three sides.
- The Indian Example: The Indian Peninsular Plateau is a classic example, flanked by the Arabian Sea (West), the Bay of Bengal (East), and the Indian Ocean (South).
