How is limestone eroded?
Then, is limestone easily eroded?
Rainwater is naturally slightly acidic because carbon dioxide from the air dissolves in it. Minerals in rocks may react with the rainwater, causing the rock to be weathered. Some types of rock are easily weathered by chemicals. For example, limestone and chalk are mostly calcium carbonate.
Beside above, how can we stop limestone erosion? You can try to prevent erosion by planting the areas around the limestone-made walls, which can deflect the wind and water. Therefore you extend the life of the limestone.
In this way, how is limestone broken down?
Figure 1: chemical weathering caused by rain water. Rain has a major impact on karst scenery through chemical weathering. 'Ordinary' rain is naturally acidic because it contains dissolved carbon dioxide that forms weak carbonic acid. When this weak acid comes into contact with calcite, the limestone begins to dissolve.
How porous is limestone?
Limestone and sandstone are highly porous and readily absorb liquids, and are particularly prone to etching, and wearing away when they come into contact with acids. Marble is also fairly porous but not as much as limestone and sandstone.
