Geological Features and Plate Boundaries

Callen Bentley explains convergent boundaries formed by plate tectonics, focusing on subduction zones, oceanic-oceanic convergence, and continental-continental collisions. The video discusses geological phenomena like volcanic arcs and mountain formation, using examples such as the Alps, Himalayas, and Mount Shasta. The tutorial aims to help viewers understand the processes and outcomes of convergent plate interactions.

What are the three types of plate boundaries?

• Convergent, Divergent, Collision

• Transform, Subduction, Collision

• Divergent, Convergent, Subduction

• Divergent, Convergent, Transform

What happens when oceanic lithosphere meets continental lithosphere?

• The oceanic lithosphere subducts

• The continental lithosphere subducts

• Both lithospheres subduct

• Neither lithosphere subducts

What geological feature is formed when oceanic lithosphere subducts under continental lithosphere?

• Continental volcanic arc

• Transform fault

• Volcanic island arc

• Mid-ocean ridge

Why does the older oceanic lithosphere usually subduct under the younger one?

• It is less dense

• It is colder and denser

• It is warmer and less dense

• It is more buoyant

What is formed when two oceanic plates converge?

• Transform fault

• Continental volcanic arc

• Volcanic island arc

• Mid-ocean ridge

What happens when two continental lithospheres collide?

• They form mountain ranges

• They form a transform fault

• Both subduct

• One subducts under the other

Which mountain range is formed by the collision of the African plate and the Eurasian plate?

• Rockies

• Himalayas

• Alps

• Andes

What geological feature is associated with the convergence of the African plate and the Eurasian plate?

• Mid-ocean ridge

• Volcanic island arc

• Transform fault

• Mountain range

Mount Shasta is an example of which type of geological feature?

• Mid-ocean ridge

• Volcanic island arc

• Transform fault

• Continental volcanic arc

Which mountain range in the United States was formed during the late Paleozoic era?

• Rockies

• Cascades

• Appalachians

• Sierra Nevada
