Which of the following does not accompany volcanic activity in the pacific northwest? slab pull subduction ocean ridge mountain building convergent boundary

Option (3)

Explanation:

The Northwestern part of Pacific ocean shares a convergent plate boundary with the North American plate, as a result of which subduction zone is formed and there occurs a trench. The denser Pacific plate sinks due to the slab pull effect and it also leads to the formation of mountains. This type of collision generates deep-focus earthquakes.

it is not associated with the oceanic ridge as the mid-oceanic ridge forms in a divergent plate boundary.

Thus, the correct answer is option (3).
