Continental Drift

Front

What is Continental Drift?

Back

Continental Drift is a theory that suggests continents have moved over geological time from a single supercontinent called Pangaea to their current locations.

Front

Who proposed the theory of Continental Drift?

Back

Alfred Wegener proposed the theory of Continental Drift in 1912.

Front

What evidence supports the theory of Continental Drift?

Back

Evidence includes matching rock types, fossils, and coastlines across different continents, as well as similar mountain ranges.

Front

What year did Alfred Wegener propose the theory of Continental Drift?

Back

Alfred Wegener proposed the theory in 1912.

Front

What technology was used during WWII to map the seafloor?

Back

SONAR (Sound Navigation and Ranging) was used during WWII to detect submarines and create the first map of the seafloor.

Front

What are some geological features that support Continental Drift?

Back

Mountain ranges on different continents with similar rock types and age support the theory of Continental Drift.

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were joined together.

Front

How do fossils provide evidence for Continental Drift?

Back

Fossils of the same species found on different continents suggest that these continents were once connected.

Front

What role do coastlines play in supporting Continental Drift?

Back

Matching coastlines of continents, such as South America and Africa, suggest they were once joined.

Front

What is the significance of SONAR in geology?

Back

SONAR technology has been crucial in mapping the ocean floor and providing insights into tectonic plate boundaries.
