Which of the following is not a negative effect of mining?
- A.
Reclamation is to expensive
- B.
Reshaping land
- C.
Water/air pollution
- D.
Toxic waste
Correct Answer
A. Reclamation is to expensiveExplanation
Mining can have several negative effects, including reshaping land, water and air pollution, and the production of toxic waste. However, the statement "reclamation is too expensive" does not represent a negative effect of mining. Reclamation refers to the process of restoring the land after mining activities have ceased, and while it can be costly, it is not inherently negative. In fact, proper reclamation can help mitigate the environmental impact of mining and restore ecosystems.Rate this question:

What is the dangerous illusion about the world's mineral supply?
- A.
New minerals are found everyday
- B.
Resource use is decreasing
- C.
Recycling will extend the supply forever
- D.
The supply is unlimited
Correct Answer
D. The supply is unlimitedExplanation
The dangerous illusion about the world's mineral supply is the belief that it is unlimited. This belief can lead to unsustainable extraction and consumption practices, as well as a disregard for the finite nature of Earth's resources. In reality, the supply of minerals is not infinite, and continued overexploitation can have detrimental environmental and social consequences. It is important to recognize the need for responsible resource management and explore alternative solutions such as recycling and sustainable practices to ensure a more sustainable future.Rate this question:

How many tons of rock are mined to get 1 ton of copper?
- A.
110
- B.
130
- C.
150
- D.
170
Correct Answer
D. 170Explanation
To obtain 1 ton of copper, 170 tons of rock need to be mined. This means that the process of copper mining involves extracting a large amount of rock to extract the desired amount of copper. The ratio of rock to copper is 170:1, indicating the significant amount of material that needs to be processed to obtain the desired copper output.Rate this question:

Why will recycling never be able to meet our mineral needs?
- A.
Corrosion of minerals
- B.
Not enough people recycling
- C.
Not economically feasible
- D.
Some minerals get lost
Correct Answer
A. Corrosion of mineralsExplanation
Recycling will never be able to meet our mineral needs because of the corrosion of minerals. When minerals are recycled, they may undergo chemical reactions that lead to their degradation or loss. This corrosion process makes it difficult to fully recover and reuse minerals, resulting in a limited supply. Therefore, recycling alone cannot fulfill our mineral requirements, and alternative methods such as mining and extraction are necessary to meet the demand.Rate this question:

Which of the following is not a use of platinum
- A.
Fertilizer production
- B.
Strengthening of concrete
- C.
Refining of gases
- D.
Catalytic converters
Correct Answer
B. Strengthening of concreteExplanation
Platinum is commonly used in various industries due to its unique properties, such as high corrosion resistance and catalytic activity. It is widely used in fertilizer production as a catalyst to enhance the efficiency of chemical reactions. Platinum is also used in the refining of gases, where it acts as a catalyst to remove impurities. Additionally, platinum is a crucial component in catalytic converters, which are used in vehicles to reduce harmful emissions. However, platinum is not used for strengthening concrete. Instead, other materials like steel or fiber reinforcement are typically employed for this purpose.Rate this question:
