Understanding Plate Boundaries

What is a transform fault, as illustrated by the San Andreas Fault?

• A fault where one plate moves over another.

• A fault where two plates collide head-on.

• A fault where two plates slide past each other.

• A fault where two plates move away from each other.

Which of the following is NOT a type of plate boundary?

• Subductive

• Convergent

• Divergent

• Transform

What geological feature is most associated with divergent boundaries?

• Volcanic arcs

• Island arcs

• Mid-ocean ridges

• Deep ocean trenches

What causes the plates to move apart at divergent boundaries?

• Gravitational pull from the moon

• Wind erosion

• Magma rising from the mantle

• Tidal forces

What is the primary cause of earthquakes along transform boundaries?

• Volcanic eruptions

• Ocean currents

• Tectonic plates sliding past each other

• Meteor impacts

Which type of plate boundary is associated with the formation of the Cascade Mountains?

• Subductive

• Convergent

• Divergent

• Transform

What happens when an oceanic plate converges with a continental plate?

• The plates slide past each other without interaction.

• Both plates move away from each other.

• The oceanic plate dives beneath the continental plate.

• The oceanic plate slides over the continental plate.

What is a common result when two continental plates converge?

• Emergence of a volcanic island

• Formation of a rift valley

• Creation of a mid-ocean ridge

• Development of a mountain range

Which of the following is a feature of convergent boundaries involving oceanic crusts?

• Rift valleys

• Mid-ocean ridges

• Island arcs

• Transform faults

Where do earthquakes most commonly occur?

• In volcanic regions only

• In oceanic trenches

• At plate boundaries

• In the middle of tectonic plates
