Galápagos Rift
Quick Summary
The Galapagos Rift is an oceanic ridge, a continuous submarine mountain chain on the ocean floor where new oceanic crust is formed through seafloor spreading. These ridges are part of a global system that defines diverging tectonic plates.12
Key characteristics include:
* Formation: Magma rises into the gap between diverging plates, creating volcanic activity and fissures in the Earth's crust.345
* Hydrothermal Vents: Seawater circulates through hot volcanic rocks, emerging as hydrothermal vents rich in minerals. These vents support unique ecosystems based on chemosynthesis.6
* Location: The Galapagos spreading center trends east-west between the East Pacific Rise and South America near the Equator.1
Oceanic ridges are the largest features in ocean basins and collectively form the most prominent feature on Earth's surface after continents and ocean basins.1
