Where is Canada?
Name 2 reasons that Wegener proposed continental drift with?
1. Land masses fit together like puzzle
2. Fossil/Plant evidence across oceans
3. Glacial Striation
4. Matching land formations across oceans

What are the North American and Pacific Plates?
What are 3 reasons why Wegener's theory was rejected?
1. No proof of how the land masses moved
2. Scientists believed that land bridges were possible
3. Does not make sense according to Physics
4. Only evidence in Soutern Hemisphere
Name an example of a Convergent Boundary on the Earth.
*See Answer*
This forms when rock splits apart, causing the thin crust of rock to sink.
