    Limestone has quite a history. Long ago, limestone was used to build the pyramids in Egypt. And Romans would mix limestone with volcanic ash to form a type of concrete for building structures in Rome. Limestone is important to making cement, but it is also found in other industries such as sugar refining, glass making, and leather tanning.

    Limestone is a sedimentary rock made of calcium carbonate CaCO 3 , usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate dolomite as well. However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present. In many cases, the grains are microscopic ...

  • How does weathering affect limestone Internet Geography

    How Does Weathering Affect Limestone Internet Geography

    Apr 12, 2021 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.

    Apr 14, 2020 Weathering creates underground caves and passages in limestone in addition to depressions and other unusual dips and grooves on the surface. Karst is landscape formed from the weathering of limestone. Limestone is a sedimentary rock created from the remains of dead sea creatures and is predominately made up of calcium carbonate.

    During the 1700s, limestone was used for lithography which is when pictures are drawn on stones and then copied to other stones. Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water.

    Marble Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.

    Oct 29, 2020 Rocks can undergo metamorphosis when they endure pressures of 100 megapascals or more. These extreme conditions converge to create a physical andor chemical change in the original, or protolith rock. After this process, the protolith rock will often change texture, composition and mineralogy to create a new completely different rock form.
