Convergent Boundaries

• Subduction - the process when the lithosphere
  plunges back into the interior of the Earth

4
Convergent Boundaries

• Trench - a V-shaped valley on the ocean floor
  where ocean floor is subducted

5
Convergent Boundaries

• Oceanic crust and Continental crust

6
Convergent Boundaries

• When oceanic crust and continental crust
  converge, the ocean plate is subducted and
  volcanic mountains form.

7
Convergent Boundaries

• Oceanic crust and Oceanic crust

8
Convergent Boundaries

• When two oceanic plates converge, the older ocean
  plate is subducted and island arcs form.

9
Convergent Boundaries

• Continental Crust and Continental Crust

10
Convergent Boundaries

• When two continental plates converge, the edges
  fold up to form mountains.

13
Divergent Boundaries

• When two continental plates diverge, a rift
  valley forms.
