Limitations Of Continental Drift Theory
The Continental Drift Theory had some limitations they are mentioned below:
- Wegener was unable to clarify why the drift started during the Mesozoic epoch.
- According to Wegner, the forces that propelled the movement of continents were buoyancy, tidal currents, and gravity, but these forces were too weak to move continents.
- Pangaea is acknowledged by contemporary ideas (Plate Tectonics), although the explanation disproves Wegner’s theory of drifting.
- His explanation of how the SIAL (Silica-Aluminum)-based continental crust, which is floating over the SIMA (Silica-Magnesium)-based ocean floor, formed island arcs that, according to him, were formed during the drifting of continents as a result of friction, fell short.
- Later Plate Tectonic Theory demonstrated that the entirety of SIAL and SIMA is floating over the asthenosphere
Continental Drift Theory: Definition, Evidence, Limitations
The Continental Drift Theory proposes that Earth’s continents were once part of a single supercontinent called Pangaea, which later fragmented and drifted to their current positions over millions of years. This theory, initially proposed by Alfred Wegener, is supported by evidence such as matching coastlines, geological similarities, and fossil distribution across continents. The concept laid the foundation for the modern understanding of plate tectonics.
In this article, We have discussed the Continental Drift Theory and supporting evidence for the Drift Theory, and limitations of the theory, and many more.
