Continental Drift

Front

What is Continental Drift?

Back

The theory that all continents were once part of a single landmass that broke apart and drifted to their current locations over millions of years.

Front

What evidence supports the theory of Continental Drift?

Back

Fossil evidence, glacier scars, matching mountain ranges, and the fit of continents like puzzle pieces.

Front

What was Pangaea?

Back

A supercontinent that existed around 335 million years ago, where all continents were joined together.

Front

Who proposed the theory of Continental Drift?

Back

Alfred Wegener.

Front

What are glacier scars?

Back

Marks left on the Earth's surface by the movement of glaciers, indicating past cold climates.

Front

What is the significance of fossil evidence in Continental Drift?

Back

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

Front

What is the role of plate tectonics in Continental Drift?

Back

Plate tectonics explains the movement of the Earth's lithosphere, which causes continents to drift.

Front

What is the difference between Continental Drift and plate tectonics?

Back

Continental Drift refers specifically to the movement of continents, while plate tectonics encompasses the movement of all tectonic plates, including oceanic plates.

Front

What is the concept of 'fit' in Continental Drift?

Back

The idea that continents can fit together like pieces of a puzzle, supporting the theory that they were once joined.

Front

What is the importance of coal deposits in understanding Continental Drift?

Back

Coal deposits found in cold regions suggest that those areas were once located in warmer climates, supporting the idea of continental movement.
