Which is the fastest-spreading mid-ocean ridge on Earth?
Quick Answer
The East Pacific Rise is among the fastest-spreading mid-ocean ridges on Earth. In some places, the plates move apart by more than 14 centimeters per year combined.
The Full Story
The East Pacific Rise is a major mid-ocean ridge in the Pacific Ocean and one of the fastest-spreading centers on Earth. In certain segments, the seafloor spreads at more than 14 centimeters per year overall, which is exceptionally fast in plate-tectonic terms. This rapid spreading creates new oceanic crust and shapes underwater volcanic activity. The East Pacific Rise is a key location for studying how the ocean floor grows.
