An old method for breaking boulders was to put them in a hot fire and then to douse them with cold water. Why would this fracture the boulders?
Step 1 of 3
Solution: Where the heat of boulder through, it expands throughout its bulk. The outer layers expand first, of course. When you then rapidly cool the surface, the surface shrinks to the point at which it can no longer hold the (hot, expanded) interior, and the boulder breaks.
