3.
a. Describe the chemical weathering process of carbonation.

b. Why is carbonation greater in cold climates?

4. Think of examples of how chemical weathering may benefit people.



Answer :

Final answer:

Chemical weathering process of carbonation, its relation to cold climates, and the benefits of chemical weathering.


Explanation:

Chemical weathering process of carbonation: Carbonation is a type of chemical weathering where carbon dioxide in the atmosphere combines with water to form carbonic acid. This weak acid reacts with minerals like limestone, causing them to dissolve and break down over time.

Carbonation in cold climates: Carbonation is greater in cold climates due to the presence of more carbon dioxide in the soil, leading to increased acidity in water that percolates through the soil.

Benefits of chemical weathering: Chemical weathering can break down rocks into soil, releasing nutrients for plant growth, helping in the formation of fertile land for agriculture, and playing a role in the carbon cycle.
