More specifically, it is a type of chemical weathering called carbonation. This is because the acid involved is typically carbonic acid (H2CO3), which forms when carbon dioxide from the atmosphere dissolves in water.
Here's a breakdown:
* Chemical weathering: The breakdown of rocks through chemical reactions.
* Carbonation: A specific type of chemical weathering where the acid involved is carbonic acid.
* Carbonic acid: Forms when carbon dioxide (CO2) dissolves in water (H2O). This reaction is reversible, meaning the carbonic acid can also break down into water and carbon dioxide again.
Example: Limestone, which is primarily composed of calcium carbonate (CaCO3), is susceptible to carbonation. When rainwater, containing dissolved carbon dioxide, comes into contact with limestone, the carbonic acid reacts with the calcium carbonate to form calcium bicarbonate (Ca(HCO3)2), which is soluble in water. This process leads to the dissolving and erosion of the limestone.
