How Does Limestone Affect the Environment?
· The actual mining process also changes existing waterways, adding additional water to streams and other bodies of water that not only floods the surrounding area, but adds pollutants to it as well. At the same time, it draws water from other features such as lakes and ponds. Limestone can be damaged by the environment through weather and water erosion. The stone absorbs water that can .

An Explanation of How Limestone Caves are Formed at .
Limestone is a sedimentary rock mainly composed of calcium carbonate and calcite formed by marine organisms like coral, shellfish and algae. It holds up to 10% of the total volume of the sedimentary rocks. A pure limestone is white in color, however, with impurities like sand, minerals and clay, limestones are found in different colors too. It can also be found in different structures like ...

A limestone cave or cavern is a natural cavity that is formed underneath the Earth's surface that can range from a few metres to many kilometres in length and depth. Most of the world's caves, including those at the Cradle of Humankind, are formed in porous limestone. Over millions of years, acidic groundwater or underground rivers dissolve away the limestone, leaving cavities which grow ...

In many limestone areas, the chemical weathering processes of solution and carbonation have produced distinctive landscapes known as karst landscapes. Karst landscapes are dominated by features such as sinkholes, disappearing streams and caves. One well known karst landscape in the Caribbean is the Cockpit Country in Jamaica. On the map of Jamaica below, the Cockpit Country is shown as an area ...

How does weathering affect limestone? Internet Geography
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.

· Karst is an area of land made up of, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or dissolved from a weak point inside the rock.

Explain the formation of limestone features
This abundance of water, heat and calcium carbonate are the exact requirements for the chemical weathering process of carbonation. In carbonation, rain mixes with carbon dioxide gas in the atmosphere to produce a weak acid called carbonic acid. Limestone is a porous rock, this means it allows water to pass through it. This acid enters the structure of limestone through its cracks, pores ...

Limestone Wikipedia
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
