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

What was Pangaea?

Back

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

Front

Who proposed the Continental Drift Theory?

Back

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

Front

What evidence supports the Continental Drift Theory?

Back

Evidence includes the fit of continental coastlines, similar rock formations, fossil distribution, and ancient climate indicators.

Front

What is the significance of fossil distribution in supporting the theory?

Back

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

Front

What force did Wegener suggest was responsible for continental movement?

Back

Wegener could not explain the force that moved the continents, which was a major reason his theory was initially rejected.

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movements of Earth's lithosphere, which includes the movement of continents.

Front

How does plate tectonics relate to the Continental Drift Theory?

Back

Plate tectonics provides the mechanism for how continents drift, explaining the forces behind their movement.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust moves away, contributing to continental drift.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.
