Plate Techtonics

What drives the movement of Earth's lithospheric plates?

• Convection currents in the mantle

• Volcanic eruptions

• Tidal forces from the Moon

• Earth's rotation

Which type of plate boundary is associated with the creation of new crust?

• Convergent

• Divergent

• Transform

• None of the above

What is the process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle?

• Subduction

• Convection

• Plate Tectonics

• Seafloor Spreading

What is the boundary called where two plates move apart?

• Convergent boundary

• Divergent boundary

• Transform boundary

• None of the above

What geological features are associated with divergent plate boundaries?

• Volcanoes, mountains, and earthquakes

• Islands and deep ocean trenches

• Rift zones and mid-ocean ridges

• None of the above

This type of plate boundary slides past one another and is known for causing earthquakes

• Subduction

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
