Plate Tectonics Review

The geologist that came up with the Theory of Continental Drift is _______

• Albert Einstein

• Alfred Wegener

• Harry Hess

• Ben Franklin

The Theory of Continental Drift states that

• Continents gradually move across Earth's surface over time.

• The plates move because of the convection currents.

• Earth's lithosphere is composed of a number of plates.

• A supercontinent that incorporates all landmasses on Earth.

The Theory of Plate Tectonics states that

• A supercontinent composed of all the landmasses.

• The gradual movement of the continents over the surface.

• The Earth's lithosphere is composed of a number of plates.

• The plates collide and cause earthquakes.

A supercontinent that is comprised of all landmasses

• Gondwana

• Laurasia

• North America

• Pangaea

Why does Pangaea no longer exist?

• It still exists today.

• Continental Drift shifted the plates causing it to separate.

• Convection Currents shift the plates causing it to separate.

• Volcanic activity causes the continents to shift.

The difference between oceanic and continental plates is

• oceanic plates are more dense and lower elevation.

• continental plates are more dense and lower elevation.

• oceanic plates are less dense and higher elevations.

• continental plates are less dense and lower elevation.
