Here's why:
* Formation: The Galapagos Islands are volcanic islands formed by hotspots. Hotspots are areas within the Earth's mantle where plumes of unusually hot magma rise to the surface, creating volcanoes.
* Composition: The islands are primarily composed of basalt, a dark-colored volcanic rock.
* Active Volcanoes: Several volcanoes on the islands are still active, with recent eruptions occurring in the last few decades.
* Unique Landforms: The volcanic activity has created a diverse landscape with unique features like lava flows, craters, calderas, and shield volcanoes.
This volcanic activity has played a crucial role in shaping the islands' unique ecosystem, including the evolution of its famous endemic species.
