Continental Drift Theory

Front

What is the Continental Drift Theory?

Back

The Continental Drift Theory is the hypothesis that continents have moved over geological time and were once joined together in a single landmass called Pangaea.

Front

Who proposed the Continental Drift Theory?

Back

Alfred Wegener proposed the Continental Drift Theory in the early 20th century.

Front

What evidence did Wegener use to support his theory?

Back

Wegener used fossil evidence, geological similarities, and climatic evidence to support his theory.

Front

What is fossil evidence in the context of Continental Drift?

Back

Fossil evidence refers to the discovery of similar fossils on different continents, suggesting that these continents were once connected.

Front

What is climate evidence in the context of Continental Drift?

Back

Climate evidence refers to the presence of warm-weather plant fossils in currently cold regions, indicating that these areas had different climates in the past.

Front

What are the two continents that fit together based on Wegener's Theory?

Back

Africa and South America fit together based on Wegener's Theory.

Front

Why was the discovery of land reptile fossils on different continents significant?

Back

It was significant because land reptiles cannot swim, suggesting that the continents were once connected.

Front

How did scientists initially react to Wegener's theory?

Back

Scientists initially did not accept Wegener's theory, as they found it difficult to believe that continents could move.

Front

What is the concept of Pangaea?

Back

Pangaea is the name given to the supercontinent that existed during the late Paleozoic and early Mesozoic eras, before it began to break apart.

Front

What role do tectonic plates play in Continental Drift?

Back

Tectonic plates are large sections of the Earth's crust that move and interact, causing continents to drift over time.
