The Galapagos Islands were created by volcanoes over the course of ages, born of the fires deep within the Earth’s core. Each time the plate moves, new volcanoes rise up. Most of the Galápagos Islands were made from a single shield volcano, creating a high point on each island, with gentle slopes and a flat coastline. Because Earth’s upper crust is cool and protects us from the heat. However, the geology of the islands is also fascinating. Some have come to follow in the footsteps of famed naturalist Charles Darwin, who visited Galapagos in 1835, and from where he got the inspiration to write his Theory of evolution. As it breaks the earth’s surface it becomes lava, which then cools into new rock. The islands were formed through the layering and lifting of repeated volcanic action… The Galapagos islands are a volcanic island archipelago formed over millions of years. It is formed by 13 main islands: Darwin, Wolf, Pinto, Marchena, Genovesa, Fernandina, Isabela, Santiago, Baltra, Santa Cruz, San Cristóbal, Floreana, as well as countless islands … The islands are formed from shield volcanoes and lava plateaus. The Old and the New Millions of years’ worth of volcanic activity in the Galápagos have created the islands’ conical structures, similarly found in Hawaii.

The origin of the Revillagigedo Islands is volcanic and began a little more than 3 million years ago, when there was a separation of tectonic plates in the area. The older extinct volcanoes form a chain of islands. The rare Galapagos pink land Iguanas, which inhabit Isabela’s Wolf volcano, are considered at-risk because its numbers and habitat are so small that an inopportune eruption could wipe them out.

One of the processes that is key to the formation of the Galapagos Islands involves plate tectonics.The structure of the Earth is made up of many layers; a very hot inner core (4,000°C), the outer core (3,500°C), the lower mantle and upper mantle which are liquid, and a solid crust. Repeated eruptions can form lava cones that make up the distinct shape of active volcanoes. Basaltic lava is much more liquid than other types of lava, and for this reason it goes further and creates a much less steep. South America.
