CONTINENTAL DRIFT THEORY

Front

What is the name of Alfred Wegener's theory?

Back

Continental Drift Theory

Front

What is Pangaea?

Back

A supercontinent that existed in Earth's distant past.

Front

How does fossil evidence support Wegener's hypothesis of continental drift?

Back

Similar fossils are found along continental margins that appear to join together, fossils are found in areas where the present-day climate could not have supported the organisms that made the fossils, and similar fossils of giant, land-dwelling dinosaurs are found on continents separated by oceans.

Front

Why was Wegener's theory not accepted?

Back

He had no proof of how the continents were moving.

Front

True or false: Coal found in colder climates indicates that the land used to be in a warmer climate.

Back

True

Front

What is the main idea of the Continental Drift Theory?

Back

The continents were once joined together and have since drifted apart.

Front

What evidence did Wegener use to support his theory?

Back

Fossil evidence, geological similarities, and climatic evidence.

Front

What is the significance of the fossil evidence found on different continents?

Back

It suggests that continents were once connected, allowing species to inhabit those areas.

Front

What role do plate tectonics play in the Continental Drift Theory?

Back

Plate tectonics explains the movement of the continents over geological time.

Front

What is the difference between Continental Drift and Plate Tectonics?

Back

Continental Drift focuses on the movement of continents, while Plate Tectonics includes the movement of the Earth's lithosphere as a whole.
