WebWherever continents are bordered by deep-sea trench systems, as in the Pacific Ocean, the ocean floor is plunged downward, underthrusting the continents and ultimately reentering and dissolving in Earth’s mantle, from which it had originated. (See also continental drift.) WebThe plate boundary is a broad zone of deformation with a width of about 60 miles (100 kilometers). Along much of the boundary, the bulk of the motion occurs along the San Andreas Fault. Point Reyes National Seashore and Golden Gate National Recreation Area are the only two NPS sites that are right on the San Andreas Fault.
WebPretty much all oceanic plates are made of basalt (and its intrusive form, gabbro), laid down from midocean ridges where they are constantly (and slowly) regenerated. Basalt is the dark-colored lava rock generated at Hawaiian type volcanoes. ^One of my old photos from Hawaii, at Kilauea WebThis is marked on the ocean surface by the presence of the Peru-Chile (or Atacama) Trench. The friction between the plates prevents the subducting oceanic plate from sliding smoothly. As it descends, it drags against the …

Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
