Carbonation is another type of chemical weathering. Carbonation is the mixing of water with carbon dioxide to make carbonic acid. This type ofweathering is important in the formation of caves. Dissolved carbon dioxide in rainwater or in moist air forms carbonic acid, and this acid reacts with minerals in rocks.

The answer option which is not an example of chemical weathering is: d.  ice wedging in rock.

Weathering can be defined as both the chemical and physical breakdown of a rock into smaller fragments (pieces) that are referred to as sediments.

Generally, there are two (2) main types of weathering and these are;

I. Physical weathering.

II. Chemical weathering.

Furthermore, the different examples of weathering include the following:

  • Natural plant acid breaking down a rock.
  • Oxidation of metals.
  • Acid rain deteriorating a marble statue.

However, ice wedging in rock is not an example of chemical weathering.

Ice wedging is mainly caused as a result of the reaction between oxygen and water but not weathering.
