Plate Tectonics and Continental Drift Theory

Front

What are convection currents in relation to plate tectonics?

Back

Convection currents provide the energy to move the tectonic plates.

Front

True or False: Continental crust is more dense than oceanic crust.

Back

False

Front

What type of boundary is the San Andreas fault?

Back

Transform boundary.

Front

How do fossils of palm trees in Alaska support the Theory of Continental Drift?

Back

Alaska was once located near the equator.

Front

What other evidence can scientists use to support the Theory of Continental Drift besides fossils?

Back

Rocks.

Front

What is the Theory of Plate Tectonics?

Back

The theory that explains the movement of the Earth's plates and how they interact.

Front

What are tectonic plates?

Back

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

Front

What is a convergent boundary?

Back

A tectonic boundary where two plates collide, often forming mountains or causing earthquakes.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move apart, often creating new crust.

Front

What is a transform boundary?

Back

A tectonic boundary where two plates slide past each other, causing earthquakes.
