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:

To solve this, we analyze each option:

• Mid - ocean ridges and rift valleys are formed at divergent boundaries (where plates move apart), and convection currents drive plate movement, not formed at convergent boundaries.
• Island chains (like volcanic island arcs) form at convergent boundaries where an oceanic plate subducts under another plate, leading to volcanic activity that creates island chains.

Answer:

A. formation of island chains
