1. Limestone Scenery

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

3. 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

4. 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.

5. 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.

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