Answer:
- 1. <u> d. hydrolysis </u> chemical reaction involving ions in water (OH⁻ and H⁺ )
- 2. <u> e. oxidation </u>chemical reaction in which minerals are weakened by oxygen
- 3. <u> b. abrasion </u> away or grinding by friction
- 4. <u> a. weathering </u> breakdown and change of rocks and minerals over time
- 5.<u> c. dissolution </u> process of dissolving
Explanation:
<u><em>a. Weathering </em></u>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.
<u><em>b. Abrasion </em></u>is the wear caused by the friction of the materials.
<u><em>c. Dissolution</em></u> is the process of dissolving a solute in a solvent. For instance, salt in water.
<u><em>d. Hydrolisys</em></u> is the chemical reaction of a substance with water, being the ions H⁺ or OH⁻ from water the agents responsible for the reaction.
<u><em>e. Oxidation</em></u> 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.
Answer:
c. meters
Explanation:
Coordinates are measured as northings and eastings. Northings are measured in meters from the equator.

Answer:
B. Sun
Explanation:
The hot plate will definitely represent the sun because it is the source of heat which will make the water boil and evaporate just as the sun would heat up oceans and other bodies of water to cause evaporation of water, which rises as valour and form clouds.
