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): 2, 4, 1, 3

4. When two oceanic plates converge, an ___ is created.: island arc

5. The Himalayas and other mountain ranges are the result of the convergence of two ___ plates.: continental

6. When two continental plates converge, ___.: mountains grow upward

7. The tallest mountains on Earth are in the ___, which formed by two continental plates converging.: Himalayas

8. ___ is geologic activity that takes place away from plate boundaries.: Intraplate activity

9. What caused the bend in the Hawaii-Emperor volcanic chain?: The Pacific Plate changed its direction of motion.

10. Which volcano lies above the Hawaiian hotspot?: Kilauea
