Limestone Scenery

Firstly, the processes that shape limestone scenery Freeze-Thaw Carbonation Solution Acid Rain Hydrolisis Oxidation

Carbonation Rainwater contains carbon dioxide which produces a weak carbonic acid This acid reacts with rocks composed of calcium carbonate especially limestone. This process causes the limestone to dissolve It is later removed in solution The process causes distinctive landscapes

Solution This is when a substance, in this case limestone, has been dissolved into a liquid. Oxidation This occurs when the minerals in the limestone take up some of the oxygen which has dissolved, and causes rocks to crumble.

Acid Rain Human activity has resulted in more carbon dioxide, sulphur dioxide and nitrogen oxide in the atmosphere. These gases then form acids in solution in rainwater The acid rain attacks some rocks, especially limestone and sandstone.

Hydrolisis This is when the hydrogen contained in the rainwater reacts with the limestone, causing it to breakdown.
