What are 4 types of chemical weathering?
Types of Chemical Weathering
- Carbonation. When you think of carbonation, think carbon!
- Oxidation. Oxygen causes oxidation.
- Hydration. This isn’t the hydration used in your body, but it’s similar.
- Hydrolysis. Water can add to a material to make a new material, or it can dissolve a material to change it.
- Acidification.
