Axel Perez Week 5 Convergent Plate

This time I took a trip down to the Andes Mountain range. This is an example of a convergent boundary between an oceanic and continental plate. It is a continental plate because a powerful collision occurs. Two thick continental plates collide, and both have lower density than mantle which prevents subduction.

 Fragments of crust sediments caught in the collision zone between the continents, forming a highly deformed melange of rock. It is a oceanic boundary as well because one oceanic plate subduct beneath the other. The subductiing plate is heated and its forced deeper into the mantle. Magma champers form and this produces an island chain.
