Boundary/Topography Quiz

How do mountains form?

• An ocean plate sinks beneath another plate and begins to melt, sending melted rock to the surface, which forms volcanic mountains or islands.
• Hot rock from within the earth risies through ocean floor as plates separate. This forms a volcanic mountain chain, or ridge, on the ocean floor.
• Two continental plates collide, and the land folds and crumples like paper.
• All of the above.

 When a continental plate and an oceanic plate collide, the oceanic plate slides beneath the continental plate. This is called subduction. Why does this happen?

• The oceanic plate has water on top of it so it sinks.
• The continental plate is denser therefore it pushes down the oceanic plate.
• The oceanic plate is denser causing it to slide beneath the less dense continental plate.
• The continental plate is thicker therefore it stays on top.

The diagram above shows an oceanic-continental subduction zone. Which of the following accurately describes an effect of subduction in this setting?

• Magma rises upward through the overriding continental plate.

• The continental plate plunges below the oceanic plate and is recycled into the Earth's interior.

• A trench forms in the asthenosphere below the continental plate.

• A volcanic arc forms on the subducting oceanic plate.
