Which describes Sand?

• A. Sand is a metallic mineral resource
• B. Sand is a fossil fuel
• C. Sand is a nonmetallic mineral resource
• D. Sand is a noble gas

Answer: (C)

The concept being tested is how mineral resources are categorized. Sand is a solid, naturally occurring material made mostly of silicon dioxide (quartz) and is considered a mineral resource. It’s placed in the nonmetallic category because it does not contain metal elements that can be mined for a metal ore, and its common uses (like making glass, cement, and construction materials) come from its nonmetallic properties. It’s not a fossil fuel, since fossil fuels are carbon-rich liquids or gases that burn for energy, and sand does not burn. It’s also not a noble gas, which are inert gases at room temperature. So sand fits best as a nonmetallic mineral resource.
