Question

1. why has demand for rare earth minerals increased in recent years? (1 point)

they are used in a growing number of electronics.
they are valued because they do not rust or corrode.
they can be sold for a high price as limited quantities are available.
they are needed to extract oil and natural gas from rock.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Rare earth minerals are crucial components in many modern electronics (like smartphones, computers, renewable energy technologies). As the electronics industry and related tech sectors grow, demand for these minerals increases.
• Option 2: Materials that do not rust or corrode are typically metals like gold, platinum, or stainless steel alloys, not rare earth minerals. So this is incorrect.
• Option 3: While rare earth minerals are limited, the main driver of increased demand in recent years is their use in expanding industries (not just their scarcity - driven price). So this is not the primary reason.
• Option 4: Extracting oil and natural gas from rock (fracking) uses materials like sand, water, and chemicals, not rare earth minerals. So this is incorrect.

Answer:

A. They are used in a growing number of electronics.
