WebMid-oceanic ridges run across the abyssal plains, such as the mid-Atlantic ridge. 2 Magma rising along the mid-oceanic ridges causes the two plates on either side to be pushed apart. The abyssal plains move with the plates, resulting in changes to ocean basins such as the Atlantic, which has opened and closed a number of times in the geological past. WebRidges are characteristic curves of a surface that mark salient intrinsic features of its shape and are therefore valuable for shape matching, surface quality control, visualization and various other applications.
