Chemical Weathering – Definition, Processes and Types
Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment. " Chemical weathering happens because the processes are gradual and ongoing, therefore changing the mineralogy of the rocks over time that makes them to wear away, dissolve, or disintegrate.

weathering process that affect limestone
Weathering (deterioration caused by exposure to the environment) is a natural part of the normal geologic cycle. For example, the process of weathering has turned the hard rocks of the Piedmont Plateau into the soft sediments washed downriver to form the Coastal Plain. Similar weathering processes affect the stones in buildings and monuments.
