- 1. What happens when an oceanic plate and a continental plate converge?
- The oceanic plate subducts beneath the continental plate.
- 2. Two lithospheric plates come together and one sinks beneath the other at a ___ zone.
- subduction
- 3. Order the following events in the creation of an island arc: the subducting plate causes melting in the mantle above it (1); two oceanic plates converge (2); the magma finds a crack in the crust and fills a magma chamber beneath a volcano (3); the older, denser plate subducts into a trench (4)
