Out Of Rock Video Quiz

None of the nations listed have all of the minerals they need. This implies that there is no single nation that has access to all the minerals required for its needs.

Gold is the correct answer because it is a highly valuable and widely traded mineral that can be bought and sold anytime and anywhere in the world. Gold has been used as a form of currency and a store of value for centuries, making it a popular choice for investors and traders. Its universal acceptance and liquidity make it easily tradable, allowing individuals to buy or sell gold in various forms, such as bars, coins, or even electronically, at any time and from any location.

Gypsum is a mineral that is commonly used in walls. It is a soft sulfate mineral that is composed of calcium sulfate dihydrate. Gypsum is widely used in construction as a material for making drywall or plasterboard. It is known for its fire-resistant and soundproofing properties, making it an ideal choice for walls. Gypsum is also used as a soil amendment in agriculture and as a filler in various products.

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.

Americans use 10 tons of nonfuel mineral resources each year.

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.

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.

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.

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.

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.
