oceanic ridges

Oceanic ridges are underwater mountain ranges formed by tectonic plate movements. They occur where two oceanic plates pull apart, allowing magma from the Earth's mantle to rise and create new oceanic crust. This process leads to volcanic activity and the formation of features like hydrothermal vents. Oceanic ridges are significant because they play a crucial role in the Earth's geology, influencing ocean circulation and ecosystems. They are the longest mountain ranges on Earth, stretching over 65,000 kilometers across the ocean floors, and are essential in understanding plate tectonics and the dynamics of our planet.
