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. WebFrost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term …

WebPhysical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart. When the ice melts, more water can get into the larger crack; if it freezes ...
