Question 45 2 pts 45. As a result of oceanic crust being subducted under a continent, magma most likely will erupt from a a. Mid oceanic ridge b.Composite volcano c.Island chain d.Rift Valley

Answer 1

Answer: Option (B)

Explanation: When a denser oceanic plate collides with a less denser continental plate, then the denser oceanic plate gets subducted below the continental plate. And due to this subduction, a deep sea trench is formed and the subducted plate undergoes partial melting and slowly magma rises to the surface forming a composite volcano.

Thus the correct answer is option (B).
