1.
When two plates converge, one plate is usually forced to slide under the other. Oceanic plates are more dense than continental plates. If an oceanic plate collides with a continental plate, what will be the likely result?
a)
The continental plate will slide under the oceanic plate, generating an oceanic trench.
b)
The oceanic plate will slide under the continental plate, generating an oceanic trench.
c)
The continental plate will slide under the oceanic plate, generating an earthquake.
d)
The oceanic plate will slide under the continental plate, generating an earthquake.
