    Figure 9. Explorer view of a ridge-centered plume. The ridge has captured the plume, dividing the upper plume into two diverging portions.


    Figure 10. Explorer view of a plume that 'got away'. Here, the ridge does not influence the travels of the upwelling plume. Plate motion to the left deflects the upwelling plume toward the left, away from the ridge.
