A convergent boundary is where two plates
c)Collide
Compare and contrast how mountains are made and how volcanic mountains are
made.
Both are made when two plates collide. Mountain building can be made by two continental
crust colliding with each other creating a mountain. Volcanic mountains are made by
subduction when an oceanic plate collides with a continental plate.
To make the Cascade volcanoes in Northeaster California, the Juan de Fuca plate
collides with the
a) North American Plate
1
The process when oceanic crust collides with continental crust.
d)Subduction
_____________________ is the area where two lithospheric plates come together
and one sinks beneath the other.
Subduction zone
Why will oceanic crust subduct beneath the continental crust?
Oceanic crust is denser than continental crust.
Subduction creates this feature.
a) Trench
How is subduction important in the rock cycle?
The oceanic crust brings rock back to the mantle when it collides and sinks under the
continental crust and turn it back into magma. The magma may erupt through a volcano or
cool beneath the surface turning the magma into igneous rock.
