Questions and Answers
What is the theory proposed by Alfred Wegener in 1915 regarding the Earth's crust?
The theory proposed by Alfred Wegener is known as continental drift, which states that parts of the Earth's crust drift slowly atop a liquid core.
How does the fossil record provide support for the theories of continental drift and plate tectonics?
The fossil record supports these theories by showing the same type of fossils found in distant continents, indicating they were once connected.
Who was Edward Suess and what was his significant discovery regarding continents?
Edward Suess was an Austrian geologist who discovered that there had been a land bridge connecting South America, Africa, India, Australia, and Antarctica.

Study Notes
Alfred Wegener
- Proposed the theory of continental drift in 1915.
- Suggested that the Earth's crust moves slowly over a liquid core.
- Fossil evidence supports continental drift and plate tectonics theories.
Edward Suess
- Austrian geologist who identified a historical land bridge among continents.
- Noted similar fossil types in geographically distant locations, such as between South America and Africa.
- Concluded that these land masses were once closely positioned, allowing similar species to fossilize across regions.
