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

2015-4-10When acid rain falls to the earth it undergoes a new round of physical and chemical changes. These changes may reduce the acidity and change the chemical characteristics of the water reaching the streams and lakes. Alkaline or basic soils such as those rich in limestone calcium carbonate can neutralie the acid directly. Effect of Acid

Chemical reactions destroy the bonds that hold the rocks together. This causes them to break into small pieces. One effect of chemical weathering is hydrolysis. Through hydrolysis water gets added into the chemical structure of a mineral which turns the mineral into a new one. For example hydrolysis changes feldspar into clay

Salt crystallisation is a very common and powerful weathering agent that can modify the petrophysical properties of building stone such as granite. In addition the weathering can affect the susceptibility of the stone to biological colonisation. The aims of the present study were to examine the properties of a granite weathered by sodium chloride crystallisation and to evaluate the effects of
