ES-4.5-Convergent Plate Boundaries and Subduction

Multiple Choice

BELLRINGER:

What is the area where two tectonic plates meet called?

• collision
• mid-ocean ridge
• a boundry
• a rift zone

Multiple Choice

Why are convergent plate boundaries important for maintaining Earth's surface area?

• They create new landmasses

• They recycle old lithosphere into the mantle

• They cause earthquakes

• They increase the Earth's surface area

Open Ended

Explain how the density differences between oceanic and continental lithosphere affect the process of subduction.

Multiple Select

Which features are commonly formed at oceanic-oceanic convergent boundaries?

• Volcanic island arcs

• Deep ocean trenches

• Major mountain ranges like the Himalayas

• Continental shelf deposits

Multiple Choice

What is the primary reason that lithospheric plates subduct at convergent boundaries?

• Their density is greater than the underlying asthenosphere

• They are less dense than the asthenosphere

• They are pushed by ocean currents

• They are pulled by gravity from the surface
