Study Notes
Continental Drift Theory
- Alfred Wegener proposed the theory of continental drift, which suggests that the continents have moved over time.
Alfred Wegener's Background
- Alfred Wegener graduated with his doctorate degree from the University of Berlin.
- In 1912, Wegener first hypothesized the drifting of continents.
Evidence Supporting Continental Drift
- Wegener's theory was supported by evidence such as:
- Fit of the continents
- Similarity of rock formations and fossils across different continents
Acceptance of Continental Drift Theory
- It took until the 1960s for Wegener's theory of continental drift to be finally accepted by scientists.
Continental Drift Hypothesis
- The continental drift hypothesis suggests that the continents have moved over time and were once joined together in a single supercontinent.
Causes of Continental Drift
- According to the text, the causes of continental drift are not specified, but it is implied to be related to geological processes.
Key Theorist
- Alfred Wegener was the key theorist behind the continental drift hypothesis.
Pre-Drift Continent
- Wegener estimated that a single supercontinent, Pangaea, existed before the continents drifted apart.
Contrary Beliefs
- Some scientists believed that the continents were fixed in place and had not moved, contrary to Wegener's theory.

Description
Test your knowledge about the continental drift hypothesis and the movement of tectonic plates which led to the formation of the current continents. Explore the theory of how the continents were once joined together in a single landmass and later drifted into their existing positions.
