(iii) Underground flow of water is more common than surface run-off in limestone areas. Why? Answer. This is because surface as well as underground water actively work through the chemical processes of solution and precipitation deposition occurring exclusively or interbedded with rocks, forming a variety of landforms.

Solution is also a significant process on limestone and calcium carbonate-cemented rocks like those found at War in the Pacific National Historical Park, Guam. In high latitudes frost weathering is a potentially significant shoreline weathering process because of the frequency of wetting of bare rock surfaces in the intertidal zone.

This biochemical extraction and secretion is the main process for forming limestone, the most commonly occurring, non-clastic sedimentary rock. Limestone is mostly made of calcite (CaCO 3) and sometimes includes dolomite (CaMg(CO 3) 2), a close relative. Solid calcite reacts with hydrochloric acid by effervescing or fizzing.
