The Nazca Plate is a oceanic plate located in the eastern Pacific Ocean basin off the coast of South America. When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. 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. Is the South American Plate continental or oceanic?
