The Nazca Plate is an oceanic plate located to the west of South America. What type of plate boundary occurs at the western edge of the Nazca Plate?

Ath the western edge of the Nazca Plate, a divergent plate boundary with the Pacific Plate occurs.

Explanation:

The Nazca Plate is an oceanic tectonic plate found in the eastern part of the Pacific Ocean, off the western coast of South America.

The eastern edge of the plate is in a subduction zone beneath the South American plate, and this crash has given rise to the Andes Mountains. The southern border of the Nazca plate is divergent from the Antarctic plate; the western border is also divergent with the plate of the Pacific, and the north with the plate of Cocos.

The subduction zone of the South American coast has caused that zone to be very active in seismic and volcanic activity. It is possible to emphasize the great earthquake of Valdivia of 1960, whose magnitude exceeded 9,5º in the scale of Richter, being the highest record since seismic data.
