Question

You are dropped off by helicopter at a site on the land. You are told that it is a plate boundary. Almost immediately, you feel an earthquake. You look around and note the absence of volcanoes, but you notice an offset stream channel, and find a vertical fault with two kinds of rock on either side of it. What sort of plate boundary are you most likely on?

a) divergent
b) convergent
c) transform
d) plate interior (hot spot)

Answer 1

It is b) convergent

Divergent boundaries have volcanoes, so if there is an absence, and there is faults, it’s convergent (convergent have faults)
