Front

What is Continental Drift?

Back

The theory that continents have moved over geological time from a single supercontinent to their current locations.

Front

Who proposed the Continental Drift theory?

Back

Alfred Wegener.

Front

What are tectonic plates?

Back

Large pieces of the Earth's lithosphere that move and interact with each other.

Front

What evidence supports the Continental Drift theory?

Back

Fossil evidence, similar rock formations, and the fit of continental coastlines.

Front

What is Pangaea?

Back

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

Front

What is the main force that drives the movement of tectonic plates?

Back

Convection currents in the Earth's mantle.

Front

What is Glossopteris?

Back

An ancient plant whose fossils have been found on five different continents, supporting the idea of continental drift.

Front

Why was the Continental Drift theory initially rejected?

Back

Scientists did not know the force responsible for moving the continents.

Front

What is the significance of mesosaurus fossils in the context of Continental Drift?

Back

Mesosaurus fossils found in both South America and Africa suggest these continents were once connected.

Front

What role do earthquakes play in the study of tectonic plates?

Back

Earthquakes occur at the boundaries of tectonic plates, providing evidence of their movement.
