For example, the most common of these rocks is limestone, which is made of calcium carbonate (CaCO 3). As shown in Equation 1, when calcium carbonate is exposed to an acid (demonstrated using sulfuric acid, H 2 SO 4 , which is the primary acid in acid rain ), the carbonate compound (CO 3 2- ) reacts to create carbon dioxide (CO 2 ) gas and ...Limestone is a sedimentary rock, although it has a hardness of 3-4 Mohs and a density of 2.5 to 2.7 grams per cubic centimeter. The rock is primarily composed of calcite or calcium carbonate, with most of these rocks being around 95% calcium carbonate. Being so high in calcium makes limestone rock polish and smooth better.Chalk is a variety of limestone composed mainly of calcium carbonate derived from the shells of tiny marine animals known as foraminifera and from the calcareous remains of marine algae known as coccoliths. Chalk is usually white or light gray in color. It is extremely porous, permeable, soft and friable. Benthic Foraminifera: Scanning electron ...

Flowing water is the dominant natural force causing erosion and deposition on Earth. The faster the water moves, the higher the energy in a physical setting. As flowing water increases in speed, the more it may become turbulent, increasing its ability to lift and move particles.
