Summary:
- Ice wedging is common where water goes above and below its freezing point.
- This can happen in winter in the mid-latitudes or in colder climates in summer.
- When liquid water changes into solid ice, it increases in volume.
- If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can.
- Most substances get smaller when they change from a liquid to a solid.
- When the temperature is warm, water works its way into cracks in rock.
