Plate movements during the opening of the Atlantic were such that the African plate moved eastward relative to the Eurasian plate, and both plates moved away from the North and South American plates. North American Plate. Location and Formation. Located between the South America and Antarctica. It is estimated that around 40% of the world’s plant and animal species are found in South America. The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year. The east-side of the North American Plate straddles the Eurasian Plate and African Plate.This is the Mid-Atlantic Ridge where divergent tectonic plates pull apart from each other. Point Reyes National Seashore, California. Seafloor spreading is occurring at the boundary between the Along divergent boundaries like The Andes owe their existence to a subduction zone on the western edge of the South American plate; in fact, this type of boundary is often called an Andean boundary since it is the primary example. The Nazca Plate is located to the west of South America. The majority of these volcanoes were formed and are still fed by magma generated as the Nazca tectonic plate under the southeastern Pacific Ocean moves northeastward and plunges beneath the South American continental plate—a process known … India south of the Himalaya C.)North America Base your answer to the following question on the map below, which shows crustal plate boundaries located along the Pacific coastline of the United States. This interaction between both plates is largely responsible for constructing the Andes Mountains. Expert Answer.
