If they begin to melt, however — particularly as they're exposed to warmer ocean water — the shelves become thinner and the grounding line begins to retreat backward, causing the glacier to become less stable and making the ice shelf more likely to break.

A downward slope, for instance, might cause the glacier to retreat more quickly, while ridges or other topographical features might help to slow or halt the backward motion.
