During dissolution calcite weathers to form
WebH 2 O + CO 2 = H 2 CO 3 (carbonic acid) from atmosphere and plant acids dissolve most rocks through time. H 2 CO 3 + CaCO 3 (calcite) = Ca +2 + HCO 3-, a reversible process (land and oceans). Calcite is the primary mineral in limestone. Calcite also acts a a cement in sediments to form sedimentary rocks.

The … WebOct 4, 2010 · Dissolution is the most easily observed kind of chemical weathering. Over time, the action of slightly acidic solutions on the rock can leave pits and holes, and it can act to slowly enlarge and widen preexisting fractures. On a large scale, dissolution can result in a very distinct type of topography- karst topography.
