Understanding the Statements
To determine the correctness of the statements, let's analyze each one carefully.
Statement (a): Wastes are of two types, biodegradable and non-biodegradable.
- This statement is correct.
- Biodegradable wastes include organic materials that can be broken down by natural processes, such as food scraps, paper, and yard waste.
- Non-biodegradable wastes are materials that do not decompose easily, such as plastics, metals, and glass.
Statement (b): Biodegradable wastes should be separated and kept in blue colour bins for garbage collectors.
- This statement is incorrect.
- Biodegradable wastes are typically placed in green bins, while blue bins are usually designated for recyclable materials like paper and plastics.
- Proper segregation is crucial for efficient waste management and recycling.
Statement (c): Ozone is formed in the stratosphere by the action of ultraviolet radiations on oxygen.
- This statement is correct.
- Ozone (O3) is created when ultraviolet (UV) radiation from the sun splits oxygen molecules (O2) into individual oxygen atoms.
- These atoms can then react with other O2 molecules to form ozone, which is essential for absorbing harmful UV radiation in the stratosphere.
Conclusion
Based on the analysis:
- Statements (a) and (c) are correct.
- Statement (b) is incorrect.
Thus, the correct answer is option C: (a) and (c). This highlights the importance of understanding waste management practices and the formation of ozone for environmental protection.
