Weathering Process Physical Weathering Processes Freeze Thaw (Frost Shattering) Temperatures need to fluctuate above and below freezing. When the temperature drops below 0 degrees‚ water collected in rock cracks freezes and expands. When temperatures rise again the ice melts. Pressure created by expansion results in progressive weakening of the rock. At high altitudes frost-shattered material forms scree slopes. Heating & Cooling Thermal expansion & contraction of rock in response
