Question

question 7 of 20 : select the best answer for the question. 7. most of the volcanic activity that occurs in the ring of fire is a result of the a. subduction of one plate under another. b. movement of two plates away from each other. c. sliding of one plate past another. d. formation of mantle plumes away from plate boundaries. mark for review (will be highlighted on the review page) << previous question next question >>

Explanation:

The Ring of Fire is associated with subduction zones where an oceanic plate subducts under another plate (usually continental or another oceanic plate). Subduction leads to melting of the subducted plate and overlying mantle, causing volcanic activity. Option B is for divergent boundaries (like mid - ocean ridges), option C is for transform boundaries (like the San Andreas fault), and option D is for hotspots (not related to the Ring of Fire's main mechanism). So the correct answer is A.

Answer:

A. subduction of one plate under another.
