  • define the processes occuring in limestone areas

    Aug 21, 2019· For instance, limestone often breaks down because of carbonation. The sulfuric acid in acid precipitation reacts with the limestone. This replaces the rock with a new chemical product, called calcium bicarbonate Ca(HCO 3) 2. Oxidation also causes chemical weathering. Oxygen in the air reacts with chemicals in different landforms.
