Galápagos Islands (Official name: Archipiélago de Colón) are an archipelago of volcanic islands distributed around the equator in the Pacific Ocean, 972 km west of continental Ecuador. It is a UNESCO World Heritage site: wildlife is its most notable feature.

The Galápagos Islands form the Galápagos Province of Ecuador and are part of the country's national park system. The principal language on the islands is Spanish. The islands have a population of around 40,000, which is a 40-fold expansion in 50 years. The islands are geologically young and famed for their vast number of endemic species, which were studied by Charles Darwin during the voyage of the Beagle. His observations and collections contributed to the inception of Darwin's theory of evolution by natural selection.

Physical Geography:

Located in the eastern Pacific Ocean at 973 km (604 miles) off the west coast of South America. The closest land mass is the mainland of Ecuador to the east (the country to which they belong), to the North is Cocos Island 720 km (447 miles) and to the South is Easter Island and San Felix Island at 3200 km (1,990 miles).

The islands are found at the coordinates 1°40'N-1°36'S, 89°16'-92°01'W. Straddling the equator, islands in the chain are located in both the northern and southern hemisphere with Volcan Wolf and Volcano Ecuador on Isla Isabela being directly on the equator line. Española the southernmost island and Darwin the northernmost island are spread out over a distance of 220 km (137 miles).

The Galapagos Archipelago consists of 7,880 square km (3,042 sq. miles) of land spread over 45,000 square km (28,000 miles) of ocean. The largest of the islands, Isabela, measures 4,640 square km and making up half of the total land area of the Galapagos. Volcan Wolf, on Isabela is the highest point with an elevation of 1,707 m (5,600 ft.) above sea level.

The group consists of 13 main islands, 6 smaller islands, and 107 rocks and islets. The islands are located at the Galapagos Triple Junction. It is also atop the Galapagos hotspot, a place where the Earth's crust is being melted from below by a mantle plume, creating volcanoes. The oldest island is thought to have formed between 5 and 10 million years ago. The youngest islands, Isabela and Fernandina, are still being formed, with the most recent volcanic eruption in April 2009 where lava from the volcanic island Fernandina started flowing both towards the island's.
