How the Islands are formed



The Galapagos Islands are located on one of the most active volcanic regions on earth: the Nazca Plate. This plate moves eastward towards South America because of the spreading of the sea floor, at a rate of 7 cm/yr. This plate moves over a stationary area of intense heat or "hot spot" which "builds" the islands. Thus, the oldest part of the Archipielago is found at the east of the cluster.
