Question

what may occur when convergent boundaries interact?
formation of island chains
creation of mid - ocean ridges
creation of convection currents
formation of rift valleys

Explanation:

Mid-ocean ridges, rift valleys form at divergent boundaries; convection currents drive plate movement, not result from convergent boundaries. Island chains form when an oceanic plate subducts under another at a convergent boundary, leading to volcanic activity that creates island arcs/chains.

Answer:

formation of island chains
