Plate Tectonics & Plate Boundaries

Multiple Choice

What happens where an oceanic plate converges with a continental plate?

• The denser oceanic plate slides on top of the less dense continental plate.

• The denser oceanic plate slides under the less dense continental plate.

• The less dense oceanic plate slides past the denser continental plate.

• The less dense oceanic plate slides under the denser continental plate.
