In this video, you will learn more about the chemical weathering processes of hydrolysis and carbonation including where they occur, how they differ and the consequences of their occurrence.

Additional Notes:

HYDROLYSIS

Example of rock : Granite (Igneous)

Example of mineral: Feldspar

Main agent responsible: Water

What is produced from the process: Clay (which is softer and weaker than Feldspar) and soluble ions




CARBONATION

Example of rock : Limestone (Sedimentary)

Example of mineral: calcium carbonate

Main agent responsible: carbonic acid (produced when water mixes with carbon dioxide)

What is produced from the process: calcium bicarbonate (which is soluble)
