The Galapagos Islands are found 1000 kilometres (600 miles) off the west coast of Ecuador, South America. The archipelago is made up of 13 large islands, 6 smaller islands and 107 rocks and islets. The very first island is thought to have formed between 5 and 10 million years ago, as a result of tectonic activity. The youngest islands, Isabela and Fernandina, are still being formed, with the most recent volcanic eruption in 1998.
