Prominent planar surfaces (fault escarpments) along range fronts are evidence that the region continues to rip aparterosion would smooth them out if the fault movement stopped. Basins thus held much more water than they do today. a. d. Mt. O/C Convergent Boundaries: Mt. Convergent Plate Boundaries The way that plates behave when they collide depends mostly on what type of lithosphere they are made of. Magma fills in the rifts forming ridges. Accreted terrains are portions of crust that are too thick and buoyant to be subducted which are "scraped off" and become added to the over-riding tectonic plate along a convergent (collisional) plate boundary. Continental rifting processes are showcased in the steep fault escarpments and active volcanoes that characterize the western United States. Boundaries, where plates move apart, are called divergent boundaries. They practiced dry farming and exploited the fresh Sunset Crater ash A. Batholiths are the largest type of igneous bodies and occur in a linear fashion with a distance of 100km or more; laccoliths are smaller than batholiths; stocks bend the sedimentary layers above them, whereas the sedimentary layers below remain relatively undeformed. These two plates are splitting apart and forms the Mid-Atlantic ridge.
