Limestone - Wikipedia

About 10% of all sedimentary rocks are limestones. Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks. It is therefore usually associated with hills and downland, and occurs in regions with …

Weathering | What is limestone? | Limestone landscapes ...

The rain soaks into the soil and porous limestones and flows over massive limestone (CaCO 3). A chemical reaction takes place. The acid rain (H 2 SO 4) is added to the limestone (CaCO 3). This causes the formation of H 2 O (water), CO 2 (carbon dioxide) and soluble CaSO 4 (calcium sulphate).

How does weathering affect limestone? - Internet Geography

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. Burning fossil fuels also contributes to this.
