A plausible theory presented by earth scientists to explain the formation of continents and ocean basins and the various land forms is the ‘Theory of Plate Tectonics’. According to the theory, the crust of the earth has been formed out of seven major and some minor tectonic plates.
According to the earth scientists, millions of years ago, the world comprised of a supercontinent ‘Pangaea’ surrounded by the primeval ocean ‘Panthalasa’. The present continents and intervening oceans were formed due to splitting of the crust into plates due to convection currents and drifting of these plates.

Theory of Plate Tectonics
The Theory of Plate Tectonics is a widely accepted scientific theory that explains the formation of continents, oceans, and various landforms on Earth. It provides a comprehensive explanation for the movement of the Earth's lithosphere, which is divided into several large and small plates that float on the semi-fluid asthenosphere beneath.
Key Points:
- Plate Movements: The theory states that the Earth's lithosphere is broken into several plates that are constantly moving due to the heat generated by the mantle. These movements cause various geological phenomena such as earthquakes, volcanic eruptions, and the formation of mountain ranges.
- Continental Drift: The theory also explains the concept of continental drift, which suggests that the continents were once joined together in a supercontinent called Pangaea. Over millions of years, the continents have drifted apart to their current positions.
- Seafloor Spreading: Another key aspect of the theory is seafloor spreading, which occurs at mid-ocean ridges where new oceanic crust is formed as magma rises from the mantle and solidifies. This process pushes the older crust away from the ridge, creating new oceanic crust.
- Subduction Zones: Subduction zones are areas where one tectonic plate is forced beneath another into the mantle. This process is responsible for the formation of deep ocean trenches, volcanic arcs, and earthquakes.
- Formation of Landforms: The movement of tectonic plates has contributed to the formation of various landforms such as mountains, valleys, and ocean basins. For example, the Himalayas were formed by the collision of the Indian plate with the Eurasian plate.
In conclusion, the Theory of Plate Tectonics provides a comprehensive explanation for the formation of continents, oceans, and various landforms on Earth through the movement of tectonic plates. It has revolutionized our understanding of the dynamic processes that shape the Earth's surface.
