Fill in the blanks with terms given below.
1. chemical reaction involving ions in water (OH- and H )
2. chemical reaction in which minerals are weakened by oxygen
3. away or grinding by friction
4. breakdown and change of rocks and minerals over time
5. process of dissolving
a. weathering
b. abrasion
c. dissolution
d. hydrolysis
e. oxidation

Explanation:

a. Weathering is due to the reaction of rocks and minerals with the air, water and organisms, which cause the rocks and minerals to breakdown and change. This, normally, is a slow process that involves chemical and physical changes.

b. Abrasion is the wear caused by the friction of the materials.

c. Dissolution is the process of dissolving a solute in a solvent. For instance, salt in water.

d. Hydrolisys is the chemical reaction of a substance with water, being the ions H⁺ or OH⁻ from water the agents responsible for the reaction.

e. Oxidation is the chemical reaction of an element with oxygen. In such reactions, the element transform into a compound that, commonly is weaker than the element. For instance, oxygen oxidates iron producing iron oxide (rust) which is weaker than iron.
