Nazcaplattan
Naczaplatan, i ljusblått mitt på kartbilden
Nazcaplattan är en litosfärplatta under Stilla havet väster om Sydamerika och utgör tillsammans med Cocosplattan och Juan de Fuca-plattan rester av den historiska Farallonplattan. Den har fått sitt namn efter den peruanska regionen och staden Nasca.
Nazcaplattan glider in under sydamerikanska kontinentalplattan, och bildar därmed en djuphavsgrav och Anderna.

The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which float on the fluid-like (visco-elastic solid) asthenosphere. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions. This map shows 15 of the largest plates. Note that the Indo-Australian Plate may be breaking apart into the Indian and Australian plates, which are shown separately on this map.
