Collisions+Between+Continental+and+Oceanic+Crust

What is a continental crust?
 * The continental crust is a layer of igneous, sedimentary, and metamorphic rocks.

What does the layer of igneous, sedimentary, and metamorphic rocks
 * Igneous, sedimentary, and metamorphic rocks forms the continental shelves.

What is oceanic crust? What is continental collision? * Continental collision is a observable occurrence of the plate tectonics of Earth that occurs at convergent boundaries. What happens to the subduction zone? * The subduction zone gets destroyed, mountains are produces, and two continents structured together. What is the oceanic collision? * The collision of two oceanic crusts causes the formation of an island arc as one is forced to move over the other.   
 * Oceanic crust is the part of Earth's lithosphere that the surfaces in the ocean basins.
