WebIn the Atlantic Ocean, the spreading rate averages about 2.5 cm/y. Estimate how far, in kilometers, the Atlantic seafloor has spread over the past 100 million years, in kilometers. 2500 If the East Pacific Rise has a spreading rate of 12 cm/y, how far will it spread (in km) in 10 million years? 1200 WebAbout 30 million years ago North America began to override the East Pacific Rise, an oceanic spreading ridge. This activity placed a progressively longer segment of the coast in contact with the plate west of the ridge.
WebUse the above equation to calculate spreading rate. R = d/t or R = 9.5 * 107 cm / 6.5 * 107 years = 1.46 cm/yr. Notes: Ranges of Spreading throughout the world's oceans: 1cm/yr to 10 cm/yr.
