Write short notes on: Carbonation

1. The decomposition of dead matter in the soil produces CO₂ 

2. This CO₂ and the CO₂ in the air reacts with minerals in the rocks. 

3. Minerals such as feldspar and carbonates decompose when this happens. 

4. In humid climate, water adds to the weathering process. 

5. In arid climates, the absence of water in the region leads to carbonate rocks to form cliffs that are resistant. 

6. Often, carbonation and solution occur simultaneously. 

7. During carbonation, the calcium and carbonate in limestone detach from each other, thereby decomposing the limestone.
