Check for Understanding â Continental Drift
Check for Understanding – Continental Drift 1. What are two pieces of evidence to support the theory of continental drift?
2. According to the theory of continental drift, what has happened to the continents during the history of the Earth? a. They have stayed exactly the same b. They started together and moved apart c. They started apart and moved together d. They have all gotten bigger
3. Why was the theory of continental drift rejected at first?
Answer Key 1. What are two pieces of evidence to support the theory of continental drift? Answers like these would work:
Continents seem to fit together like puzzle pieces, and where continents used to touch there are common features (mountains and coal fields for example) Similar fossils have been found on continents that are now very far apart The climate of some cold places used to be much warmer Evidence of glaciers (ice) has been found in very warm places

3. Why was the theory of continental drift rejected at first? The theory of continental drift was rejected at first because no one could explain what made the continents move.
