Details
The acid dissolves rocks—a process called chemical weathering—and releases calcium, magnesium, potassium, or sodium ions. Rivers carry the ions to the ocean. ... Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their ...
Details
The goal of this experiment is to explore the formation of limestone as it happens in nature. Calcium carbonate is the main component that forms shells, and when marine life dies those shells settle on the bottom of the ocean where they collect. ... Check out this fun science fair project idea to understand the process of coal formation and ...
Details
Another formation process of Limestone occurs through evaporation. In this manner, droplets on cave walls seep down from the entrances of the cave through fractures, and this water then evaporates, leaving a calcium carbonate deposit behind, which forms limestone. 2. Uses. Limestone is a widely used product.
Details
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 …

Formation of Dolomite from Limestone. Some limestones have been changed by the introduction of magnesium in groundwater. ... This process is called "metamorphism." There are also rare "igneous" carbonate rocks that have crystallized from molten magma in the same way that lavas or granites have. These are called "carbonatites," and this rock ...

Since limestone most frequently comes from particles in water, Limestone deposits often form in or near a water supply. Coral reefs often have a limestone base with living creatures that depend on the limestone creating a layer over the rock. In certain areas, you might also find limestone formations around lakes and on dry land.
