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.
