Types of Mechanical Weathering:-


Frost Wedging - water expands when it freezes.  This photograph shows the individual layers within the sedimentary rock breaking apart through repeated cycles of freeze-thaw.  A similar process happens when the rock is repeatedly wetted and dried as salt crystals dissolve from the rock then grow when it is dried.




near the summit, is covered by a thick layer of sharp-edged boulders produced by frost wedging. Frost wedging is well-developed here because the temperature cycles across the freezing point many days each year.
