WebDefinition: Freeze-thaw weathering is a process of erosion that happens in cold areas where ice forms. A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making it larger. When the temperature rises again, the ice melts, and the water fills the newer parts of the ... WebIn this practical, students observe what happens when a bottle is filled with water and allowed to freeze. The water expands as it freezes, which breaks the bottle. This is useful when teaching about the weathering of rocks and freeze-thaw. This demonstration can be set up in one lesson and left in the freezer until the next.

During the day when temperatures are higher, the snow melts and water enters the cracks in the rock. When the temperature drops below 0°C the water in the crack freezes and expands by about 9 per cent. This makes the crack larger.
