Answer:
Erosion, compaction, nutrient imbalance, pollution, acidification, water logging, loss of soil biodiversity and increasing salinity have been affecting soil across the globe, reducing its ability to support plant life and so grow crops.
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.
