Uses of Limestone ScienceStruck

Limestone rock is a sedimentary rock which forms in the process of sedimentation at the bottom of lakes and oceans or in caves. It is mainly composed of mineral calcite and aragonite both of which are crystal forms of calcium carbonate. A limestone with 95 percent or more of calcium carbonate by weight is known as a highcalcium limestone.

How Does Limestone Affect the Environment

Full Answer. Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground caves and gullies form a natural phenomenon known as karst. Although this doesn't hurt the environment in its natural form once the limestone is mined out sinkholes can form and disrupt underground waterways.
