Each plate is moving in a different direction, but the exact direction depends on the reference frame, or viewpoint, in which you are looking at the motion. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. 2 0 obj The South American-Antarctic Ridge (SAAR or AAR) is the tectonic spreading center between the South American Plate and the Antarctic Plate.It runs along the sea-floor from the Bouvet Triple Junction in the South Atlantic Ocean south-westward to a major transform fault boundary east of the South Sandwich Islands.Near the Bouvet Triple Junction the spreading half rate is 9 mm/a (0.35 in/year . 5ed.A.^ J^/`;fdWfWdWTTTTTTTTTTTTTTT\A*L'|}w1r^GiLZ;+ endstream endobj 240 0 obj <> endobj 241 0 obj <>stream 0000003143 00000 n The Denali Pipeline in _____ was designed to withstand displacement from earthquakes in order to prevent oil spills.

That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earth's crust that roughly fit together and meet at places called plate boundaries. She or he will best know the preferred format. South American plate is involved in Andes Mountains formation with Nazca plate, and Mid Atlantic Ridge formation with African plate.
