  • Wind – carry materials which knock each other thus breaking off into small pieces moving ice glacier- as it moves it has a grinding effect water when it rains, the raindrops hit the ground with some force a dislodges the soil.
  • Temperature -- high temperature causes expansion of rocks while low temperatures cause contraction of rocks the expansion and contraction of the rocks lead to breakage.
  • Rainfall of high intensity erodes soil surfaces temperature – when water gets into the rock cracks it freezes and becomes ice increasing volume, exerting pressure on the rock then dislodges particles .
