Question

volcanic rocks are least likely to be produced in which of the following geologic settings?
subduction zone
transform fault
oceanic hot spot
mid - ocean rift

Explanation:

In a subduction zone, melting of the sub - ducting plate can lead to volcanic activity. Oceanic hot spots and mid - ocean rifts are also areas of high volcanic activity due to upwelling of magma. Transform faults are mainly characterized by horizontal movement of tectonic plates and have less magma upwelling compared to the others, resulting in less likelihood of volcanic rock production.

Answer:

B. transform fault
