what's the difference between sand and quartz? [closed]
Sand is a poorly-defined mixture, not a necessarily a pure substance.Some sands are fairly pure $ce{SiO2}$, the same chemical formula as pure quartz, but in some areas of the world, sand can be made of entirely different chemicals, such as calcite.. Quartz is a particular crystal form of $ce{SiO2}$, but $ce{SiO2}$ also forms the …

Quartz Mineral | Photos, Uses, Properties, Pictures
Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.
