ES Continental Drift/Plate Boundaries Test

Front

What does the theory of continental drift state?

Back

The continents were once joined in a super-continent and have moved over time.

Front

Why was Wegener's discovery of land reptile fossils on different continents significant?

Back

Land reptiles cannot swim, so the continents must have been connected for them to get across.

Front

What type of plate boundary is characterized by two plates colliding?

Back

Convergent.

Front

What evidence supports the theory that continents were once joined?

Back

Glacial grooves were found on different continents.

Front

Who is credited with developing the theory of continental drift?

Back

Alfred Wegener.

Front

What is a divergent plate boundary?

Back

A boundary where two tectonic plates move away from each other.

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountain ranges and deep ocean trenches.

Front

What is the significance of fossil evidence in supporting continental drift?

Back

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

Front

What are tectonic plates?

Back

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

Front

What is the role of convection currents in plate tectonics?

Back

Convection currents in the mantle drive the movement of tectonic plates.
