Continental Drift

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass.

Front

What is the main force behind Continental Drift?

Back

The movement of tectonic plates driven by convection currents in the Earth's mantle.

Front

What are tectonic plates?

Back

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

Front

What evidence supports the theory of Continental Drift?

Back

Fossil distribution, geological similarities, and the fit of continental coastlines.

Front

What is Pangaea?

Back

A supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were joined.

Front

How do fossils support Continental Drift?

Back

Similar fossils found on different continents suggest those continents were once connected.

Front

What role do ocean currents play in Continental Drift?

Back

Ocean currents can influence the movement of tectonic plates by affecting the heat distribution in the oceans.

Front

What is the significance of coal seams found in Antarctica?

Back

They indicate that Antarctica was once located in a warmer climate, supporting the idea of continental movement.

Front

What is the difference between Continental Drift and Plate Tectonics?

Back

Continental Drift is a historical theory explaining the movement of continents, while Plate Tectonics is the modern scientific theory that explains the movement of the Earth's plates.

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates, often associated with continental drift.
