To the left is a simple spreading ridge. The red designates the actual spreading center, where new sea floor is being created. The blue depicts transform faults where pieces of the sea-floor are sliding past each other in opposite directions. |

To the left students point out the symmetry of the addition of new oceanic crust around the mid-oceanic ridge. |

The next two images show a migrating (downward) transform fault. The first image is early in the time sequence, as the transform fault is still migrating down. In the second image, the migrating transform fault has terminated. |
