Copper is a mined mineral commonly used in plumbing and wiring. As Earth’s population increases, copper use also increases. Which of these statements show ways this increased use of copper affects Earth itself? A. The amount of available copper ore decreases. B. Copper becomes more expensive because it is rarer. C. People are encouraged to recycle copper. D. Pollution from mining increases. (1 point) Responses A and B A and B A, B, C, and D A, B, C, and D A and D A and D B and C

Answer 1

The correct response would be A and D.

• A. The amount of available copper ore decreases. This is true as increased use and mining reduce the amount of available copper ore.
• D. Pollution from mining increases. Increased mining activities can lead to higher levels of pollution.

While B (Copper becomes more expensive because it is rarer) and C (People are encouraged to recycle copper) are true statements, they do not directly describe how increased copper use affects Earth itself in a negative or direct environmental impact way. So the best choice focusing on the effects on Earth would be A and D.
