United States be associated with?
a. Divergent plate boundaries
b. Convergent plate boundaries
c. Transform plate boundaries

ANS: B
The continental volcanoes are a sign of convergent plate boundaries. This particular convergent
boundary occurs because the seafloor is being destroyed at a subduction zone. The dense oceanic
lithosphere plate subducts beneath the North American continental plate. Information can be found in
the section Plates Interact at Plate Boundaries.
