Ocean-Ocean Convergent Boundaries

Where two ocean plates meet, which plate will go under the other?

• The newer, less dense plate will go under the older, dense plate

• The older dense plate will go under the newer, less dense plate

• The converging ocean plates have the same density and will collide

What is the name of the zone where the trench is by two converging plates?

• Convergence zone

• Divergence zone

• Subduction zone

• Rift zone

What type of landform results at ocean-ocean converging plate boundaries?

• Mountains

• Volcanic Island Arc

• Rift valley

• Stream valley

Where do the volcanoes form at converging ocean plates?

• On the upper plate

• On the lower plate

• Above the trench

What are two types of crust?

• lower and upper

• thick and thin

• continental and oceanic

• ocean and basin

The ocean crust that moves under the upper layer of ocean crust will

• cool off and harden

• break apart

• melt and form lava that rises to the surface

• melt and form magma that rises to the surface
