Question

Which of the following is a cause of soil pollution?

• A. Deforestation
• B. Industrial waste
• C. Use of chemical fertilizers
• D. All of these

Hint:

Soil pollution comes from many sources: agricultural (fertilizers), industrial (waste), and even domestic (improper waste disposal). When you see multiple valid sources listed, "All of these" is a strong possibility.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Soil pollution is the contamination of soil with harmful substances that can adversely affect soil quality, plant growth, and human health.

Step 2: Detailed Explanation:
- Deforestation: While primarily causing soil erosion (loss of topsoil), this degradation of soil quality is a form of pollution.
- Industrial waste: Dumping of untreated industrial waste can introduce heavy metals and toxic chemicals into the soil.
- Use of chemical fertilizers: Overuse of chemical fertilizers and pesticides can alter the soil's pH, destroy its microbial ecosystem, and contaminate it with harmful residues.
All three activities are major causes of soil pollution and degradation.

Step 3: Final Answer:
Deforestation, industrial waste, and the use of chemical fertilizers are all causes of soil pollution.
