What is dissolution and how does this result in weathering?
1 Answer
Removal of some minerals (e.g. calcium carbonate) and corrosion of rocks.
Explanation:
When rocks are exposed to the external environment the minerals of which they are composed undergo to chemical attack by several agents. The most common is the chemical dissolution of soluble minerals, such as calcium carbonate, by acidic solutions.
The carbon dioxide present in the atmosphere is dissolved in the rainwater which becomes acidic. Once this acidic water impacts calcareous rocks (limestone) the calcium carbonate,
There is a number of minerals that can be dissolved by chemical agents naturally present in the environment and this leads to the progressive erosion of the landscape.
