How is limestone made
Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.Lithography is a unique art form where artists draw with greasy materials on a stone. The stone is then chemically treated to establish where water and ink will go. The drawing is replaced with ink, creating a beautiful print. This process allows for detailed and subtle artwork. .The major limestone-forming period in New Zealand was during the Oligocene, about 22–30 million years ago. At that time, New Zealand was covered almost entirely by a shallow sea. Many invertebrate organisms with calcareous shells thrived in this sea, and over time, a thick sedimentary layer of shell fragments developed.

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.Marble, granular limestone or dolomite that has been recrystallized under the influence of heat, pressure, and aqueous solutions. Commercially, it includes all decorative calcium-rich rocks that can be polished, as well as certain serpentines.No, limestone is not magnetic. Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3). It does not contain any magnetic minerals or exhibit any magnetic properties. The magnetic susceptibility of limestone is very low, indicating its non-magnetic nature.Limestone is a sedimentary rock made primarily from calcium carbonate, usually in the form of calcite and aragonite. Its grains vary in size and can consist of a variety of materials including shells, coral, and mud. It is typically off-white to gray in color and usually forms in shallow marine environments. 3.Drawing the molten glass onto the tin bath: The molten glass is then "floated" onto a bath of molten tin at a temperature of about 1000°C.
