The Nazca plate or Nasca plate, [2] named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction , along the Peru–Chile Trench , of the Nazca plate under the South American plate is largely responsible for the Andean orogeny .
These plates are often grouped with an adjacent principal plate on a tectonic plate world map. For purposes of this list, a microplate is any plate with an area less than 1 million km 2 . Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere ) like the Apulian ...
Map showing the location of Nazca Ridge off the west coast of Peru. The Nazca Ridge is a submarine ridge, located on the Nazca plate off the west coast of South America.This plate and ridge are currently subducting under the South American plate at a convergent boundary known as the Peru-Chile Trench at approximately 7.7 cm (3.0 in) per year.

The model displayed remnants of submerged plates located under oceans and in the middle of continents, which—according to our current understanding of the plate tectonic cycle—are all too far ...
The trench is 1,700 miles (2,750 km) long and is 21,880 feet (6,669 m) at its deepest point. The trench is the boundary between the Rivera, Cocos, and Nazca plates on one side and the North American and Caribbean plates on the other. It is the 18th-deepest trench in the world.
The Galápagos Rise is an extinct spreading centre located about 1,000 km (620 mi; 540 nmi) southsouthwest of the Galápagos islands, [1] and 2,000 km (1,200 mi; 1,100 nmi) west of Peru which was active in the Miocene period. It developed shortly after the Farallon plate broke into two parts, forming the Cocos and Nazca plates. During its ...
This is a tiny plate between Nazca plate and South American plate, it locates east of the Chile ridge. It is proved that Chiloe microplate (Fig-5, 6) is migrated northwards relative to the South American plate which is rather immobile. The Golfo de Penas basin is formed because of the northward movement of Chiloe microplate. [16]
The Nazca lines (/ ˈ n ɑː z k ə /, /-k ɑː / [1]) are a group of over 700 geoglyphs made in the soil of the Nazca Desert in southern Peru. [2] [3] They were created between 500 BC and 500 AD by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving different-colored dirt exposed. [4]
