Exploring Lithospheric Plates and Their Boundaries

What is the lithosphere composed of?

• Crust and the entire core

• Crust and the uppermost mantle

• Entire mantle

• Only the Earth's crust

What analogy is used to describe the behavior of rocks under different temperatures?

• Ice melting into water

• Glass breaking under pressure

• Wood bending under force

• Taffy being brittle when cold and ductile when warm

What is the typical thickness of continental crust?

• 8 kilometers

• 50 kilometers

• 40 kilometers

How thick is the oceanic crust typically?

• About 8 kilometers

• More than 100 kilometers

• Less than 5 kilometers

• Approximately 40 kilometers

Which type of plate boundary does not create or destroy lithosphere?

• Transform

• Convergent

• Subduction zones

• Divergent

What supports the oceanic ridges at divergent boundaries?

• Sedimentary rock layers

• Hot, buoyant upwelling mantle

• Subducted plates

• Continental crust

Where do the world's largest earthquakes typically occur?

• In the mantle

• Along transform boundaries

• Near convergent boundaries

• At divergent boundaries
