Abrasive action of water, ice and wind
Water is an important mechanical weathering agent both in liquid as well as in the frozen state. Rain water carrying sediments, ice glaciers moving under the influence of gravity and wind loaded with dust particles (dust storms) have enough cutting power to cause abrasion of the mineral particles they come across on the surface of the weathe ring rock. Further, water can enter into small crevices of rocks where it can freeze in winter season. The frozen water on expansion puts a force which is sufficient to split minerals and rocks.
