Question

You have a geological site associated with earthquake activity and a mountain range. You look offshore, but do not find any trenches. What type of boundary are you dealing with?

a.oceanic-oceanic convergent boundary

b.continental-continental convergent boundary

c.divergent boundary undersea

d.oceanic-continental convergent boundary

Answer 1

b. just took test hoped this help

Answer 2

The correct answer is b. continental-continental convergent boundary. In this type of boundary none sinks beneath the other as the continental crust is relatively buoyant and of the same density. No subduction takes place and both crust are folded and faulted upwards to form fold mountain ranges. Since no subduction takes place, no trench will be formed.
