WebNorthward propagation of the East Pacific Rise into the North American Plate initiates rifting off of the Baja California peninsula. 4 Ma Pliocene Sierra Nevada begins to rise. 3.5 Ma Pliocene The Pacific Plate changes its direction of motion about 11 degrees east of its previous heading, from northwest to the present northwest by north. WebJan 30, 2002 · The East Pacific Rise is a “divergent” plate boundary, where huge slabs of the Earth’s crust (plates) are moving away from each other. Near the Gulf of California, the relative motion of the plates changes so that the two plates (the North American Plate and the Pacific Plate) are moving sideways, sliding past one another. ...
