At convergent plate boundaries, one plate slides beneath anotherr in a process called subduction.

This produces basaltic magma that erupts efusively, forming new oceanic crutt and, in rare e cases, creating wulcan landscapes on land. The Eass Africain Rift is a prime example of continental rifting, where conwulcan es like Kilimanjaro and Nyiragongo built massives edificves along the spreading zone zone.
