WebThe Atlantic ocean is widening because the mid-ocean ridge creates new oceanic crust that is incorporated into the oceanic plates as they move apart. This pushes the Pacific Ocean closer together with more oceanic plate being subducted than is produced along the East Pacific Rise, so the Pacific Ocean is narrowing from east to west.
