  • Limestone: The Calcium Carbonate Chemical Sedimentary Rock

    Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an ...

  • Where Do Sinkholes Occur and How Do They Form?

    A sinkhole is a large depression in the ground that occurs as a result of underground dissolution and erosion of limestone and other carbonate rocks. Most of the time they actually form slowly, but some sinkholes appear suddenly and unexpectedly after a long process of erosion underground.

  • How does weathering affect limestone? - Internet Geography

    Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

  • Exfoliation | geology | Britannica

    Exfoliation, separation of successive thin shells, or spalls, from massive rock such as granite or basalt; it is common in regions that have moderate rainfall. The thickness of individual sheet or plate may be from a few millimetres to a few metres. Some geologists believe that exfoliation results

  • What Is Solution in Geography? - Reference.com

    Mar 25, 2020· The chemical process that occurs is one in which carbon dioxide in the presence of water forms carbonic acid that dissolves limestone. The limestone, carbon dioxide and water are all said to be in solution at that point when the limestone is dissolved. For a river to dissolve limestone, generally the water must be naturally acidic on the pH scale.

  • How Does Weathering Affect Limestone? - Reference.com

    Apr 14, 2020· Limestone is a sedimentary rock created from the remains of dead sea creatures and is predominately made up of calcium carbonate. Many horizontal and vertical cracks run through limestone. These cracks allow water to pass easily through the rock. Water acts as an acid when it contacts calcium carbonate, dissolving the limestone.

    Sep 01, 2014· Limestone is a pervious or permeable to water and can be slowly dissolved by carbonic acid ( carbon dioxide and water). The structure of limestone is like building blocks with joints (vertical) and bedding planes (horizontal) separating the blocks. Most weathering of limestone occurs between the joints when acid rain seeps in to the cracks.
