The South American Plate and the Nazca Plate are close relatives. The oceanic Nazca Plate subducts beneath the continental South American Plate at the Peru-Chile Trench. Lithospheric Plates The theory of plate tectonics proposes that the lithosphere is divided into eight major plates (North American, South American, Pacific, Nazca, Eurasian, African, Antarctic, and Indian-Australian) and several smaller plates (e. g. , Arabian, Scotia, Juan de Fuca) that fit together like the pieces of a jigsaw puzzle (Fig. The movement of plates along a tectonic boundary is referred to as convergent movement. Unit 11 - Ocean Systems This unit describes the Earth's oceans as connected systems, as well as the ocean floors, how ocean water moves, what waves are and what they do, and what causes. A zone of oblique convergence with the Sunda Plate is visible along the Philippine Sea plates western margin.
