Plate Tectonics and Earth's Structure Quiz

What is the main process occurring at the "ridge" in the diagram?

• Plates are moving apart and new crust is being formed.

• Plates are colliding and forming mountains.

• Plates are sliding past each other.

• Plates are sinking into the mantle.

What typically forms at a "trench" as shown in the diagram?

• New oceanic crust

• Subduction zones where one plate sinks beneath another

• Volcanic islands

• Earthquake epicenters only

Which layer of the Earth is directly beneath the lithosphere according to the diagram?

• Inner core

• Asthenosphere

• Outer core

• Crust

According to the diagram, what is the role of "SLAB PULL" at the trench?

• It pushes plates apart at the ridge.

• It pulls a plate down into the mantle at the trench.

• It causes volcanic eruptions at the ridge.

• It creates earthquakes at the outer core.

What is a key difference between constructive and conservative plate boundaries?

• Constructive boundaries create new crust, while conservative boundaries do not.

• Conservative boundaries create new crust, while constructive boundaries do not.

• Both boundaries destroy crust.

• Both boundaries create mountains.

What type of plate boundary is specifically mentioned in the instructions?

• Destructive boundary

• Conservative boundary

• Constructive boundary

• Transform boundary

What is another name for a constructive boundary in plate tectonics?

• Divergent boundary

• Convergent boundary

• Transform boundary

• Subduction boundary

What typically forms at mid-ocean ridges in a constructive/divergent boundary?

• Volcanoes

• Earthquakes

• Mountains

• Trenches

What happens to tectonic plates at a constructive/divergent boundary?

• Plates move away from each other

• Plates move towards each other

• Plates slide past each other

• Plates remain stationary

Where do rift-valleys occur according to the diagram?

• On continental crust

• On oceanic crust

• At subduction zones

• At transform boundaries
