FAQs on Continental Drift Theory
| 1. What is the Continental Drift Theory? |  |
Ans. The Continental Drift Theory proposes that the continents were once joined together in a single landmass called Pangaea and have since drifted apart to their current positions. This theory explains the movement of continents over geological time due to tectonic forces.
| 2. Who proposed the Continental Drift Theory and when? | |
Ans. The Continental Drift Theory was proposed by the German geologist Alfred Wegener in the early 20th century. He introduced his ideas in 1912, suggesting that continents move through the oceanic crust.
| 3. What evidence supports the Continental Drift Theory? | |
Ans. Evidence supporting the Continental Drift Theory includes the fit of continental coastlines, the distribution of similar fossils across different continents, and geological similarities in rock formations on continents that are now separated by oceans.
| 4. How does the Continental Drift Theory relate to plate tectonics? | |
Ans. The Continental Drift Theory laid the groundwork for the modern concept of plate tectonics, which explains the movement of the Earth's lithospheric plates. It provides a mechanism for how continents can drift due to the movement of these tectonic plates driven by mantle convection.
| 5. What were some criticisms of the Continental Drift Theory? | |
Ans. Critics of the Continental Drift Theory argued that Wegener could not provide a convincing mechanism for how continents drifted, as the concept of continental movement through solid oceanic crust was not widely accepted. It was not until the development of plate tectonics that these ideas gained broader support.
