This week I decided to stop at one of the most beautiful coastlines in the US that also happens to be a convergent plate boundary, the Washington Oregon coastline. This boundary is the convergence of oceanic crust and continental crust. The convergence of the plates is a subduction zone, meaning the oceanic crust is being pushed under the continental crust. This is known as a thrust fault. Eventually the crust reaches extreme temperatures and creates magma under the surface, which is responsible for the numbers of volcanoes in this region. Igneous, Sedimentary, and metamorphic rocks are all found in abundance along this coastline.
