Frost wedging

6. Oxidation is a form of chemical weathering to which what compounds are most susceptible?

Any oxide

Any carbonate

Most iron-bearing silicate minerals

All silicate minerals

7. Hydrolysis is best described as

The chemical reaction between water and CO2

The disassociation of the water molecule

Caused by the dipolar nature of the water molecule
