Chapter Review Jeopardy THANK YOU for PLAYING!!! Would you like a final Jeopardy question?

Final Jeopardy What property shown by water as it is freezing is responsible for ice wedging? The fact that water expands as it freezes means that water that has seeped into cracks in rock can widen the cracks as the water freezes into ice.
