Convergent Boundaries

Why did the oceanic plate subduct?

• Less dense
• More dense
• Heavier
• Thinner

Why didn't the oceanic plate get mountains on it?

• It hasn't been colliding long enough to fold
• It isn't stuck...so it won't fold
• Because it is made of basalt
• All answers

Why did the continental plate get mountains?

• It is made of thicker continental crust
• It gets stuck and folds
• It has a subducted plate under it that melts
• It is more dense

Why did the continental plate get volcanoes?

• It is made of thicker continental crust
• It gets stuck and folds
• It has a subducted plate under it that melts
• It is more dense

Why is there a trench in the water?

• Because of the basalt 
• Because of the melting oceanic crust
• Because the oceanic plate is subducting making a low spot
• Because the oceanic plate is stuck and folds downward

Why did the plate on the left subduct?

• More dense
• heavier
• Thinner
• Made of basalt

Why does a trench form at the boundary

• It folded down (crumpled)
• Subducted plate sunk
• It folded up (crumpled)
• All answers

Why does a trench form between the islands

• It folded down (crumpled) down
• Subducted plate sunk
• It folded up (crumpled)
• All answers

Which plate will get folded mountains?

• Plate on the left
• Plate on the right
• Both plates
• Neither plate

The plate that is stuck will do what?

• Fold up and down (crumple)
• Subduct
• Melt
• Turn into a trench
