Which of the following is not a negative effect of mining?

Reclamation is to expensive
Reshaping land
Water/air pollution
Toxic waste

Correct Answer

A. Reclamation is to expensive

Explanation

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.

What is the dangerous illusion about the world's mineral supply?

New minerals are found everyday
Resource use is decreasing
Recycling will extend the supply forever
The supply is unlimited

Correct Answer

A. The supply is unlimited

Explanation

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.

How many tons of rock are mined to get 1 ton of copper?

110
130
150
170

Correct Answer

A. 170

Explanation

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.

Why will recycling never be able to meet our mineral needs?

Corrosion of minerals
Not enough people recycling
Not economically feasible
Some minerals get lost

Correct Answer

A. Corrosion of minerals

Explanation

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.

Which of the following is not a use of platinum

Fertilizer production
Strengthening of concrete
Refining of gases
Catalytic converters

Correct Answer

A. Strengthening of concrete

Explanation

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.

How does Japan ensure it's flow of mineral resources?

Trade technology for resources
Trade oil for resources
Invest in a country it is trading with
Buy land in other countries to mine

Correct Answer

A. Invest in a country it is trading with

Explanation

Japan ensures its flow of mineral resources by investing in a country it is trading with. By investing in the country, Japan establishes a long-term relationship and secures a stable supply of mineral resources. This strategy allows Japan to have a direct influence on the production and distribution of resources, ensuring a continuous flow of minerals to meet its industrial needs.
