Are Spreading rates along the East Pacific Rise are relatively fast with many areas spreading more than 9 centimeters per yea?
Spreading rates along the East Pacific Rise are relatively fast with some areas spreading more than 9 centimeters per year. This is because the East Pacific Rise is part of the divergent plate boundary between the Pacific Plate and the Cocos Plate. As these two plates move apart, new oceanic crust is created in the gap between them. The spreading rate at the East Pacific Rise is about 6 centimeters per year on average, but it can vary from 2 to 16 centimeters per year in different areas. The fastest spreading rates are found near the equator, where the plates are moving apart more quickly.
