    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 (CaMgCO 3), a close relative. Solid calcite reacts with hydrochloric acid by effervescing or fizzing.

  • erosion | National Geographic Society

    Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock''s chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.
