A cordillera is a major system of often parallel mountain ranges that includes the intervening plateaus, valleys and plains. Since both plates have a similar thickness and weight, neither one will sink under the other. Along a convergent boundary two lithospheric plates collide against each other. About 250 million years ago the crustal plates constituting the Earth's landmass were joined together into the supercontinent Pangaea. Convergent. Two points: (1) plate boundaries change with time and (2) mountain ranges generally form near plate boundaries (and in response to processes happening in relation to the plate boundary), but do not have to form exactly at the boundaries between plates.

A chain of volcanoes often forms parallel to convergent plate boundaries and powerful earthquakes are common along these boundaries. That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earths crust that roughly fit together and meet at places called plate boundaries.Plate boundaries are important because they are often associated with earthquakes and volcanoes. Plate Boundary: Divergent (Fast-spreading Ridge) New oceanic crust is created at this boundary when basalt magma, formed in the mantle, rises into fractures in the crust and solidifies. Two plates sliding past each other forms a transform plate boundary. The breakup of Pangaea dispersed these plates outward, and the collision of two of these platesthe continental South American Plate and the oceanic Nazca Plategave rise to the mountain-building activity that produced the Andes Mountains.
