Apr 25, 2017· Chemical and Mechanical Weathering. Limestone is also subject to mechanical weathering, especially in dry climates, by the abrasive action of wind carrying rock fragments and other debris. This combination of chemical and mechanical weathering makes limestone very vulnerable to deterioration when exposed to the atmosphere.
