Here's how it works:
* Subduction: One plate (the denser one) slides beneath the other, a process called subduction.
* Volcanism: The subducting plate melts as it descends, creating magma that rises to the surface, forming volcanic islands.
* Island Arc: These volcanic islands often form a curved chain called an island arc.
Examples of mountains formed by oceanic-oceanic convergence:
* The Mariana Islands (Pacific Ocean)
* The Aleutian Islands (Alaska)
* The Japanese Islands
* The Tonga Islands (South Pacific)
Key takeaway: While not a single mountain, the mountains formed by oceanic-oceanic convergence are typically volcanic islands that form island arcs.
