Sand
Most sand is made up mostly of pulverized quartz. Quartz is one of the most abundant minerals on Earth and is composed of silicon dioxide (SiO2). When rocks containing quartz break down due to weathering and erosion, they form sand, which is primarily made up of small particles of pulverized quartz.
Quartzite is composed mostly of silica. It contains minerals like zircon, rutile, and magnetite, and the silica cements them together.
Sandstone is made up mostly of sediments of quartz and/or feldspar. Therefore sandstone is a clastic sedimentary rock.
Quartzite is a rock mainly found up your arse.
Felsic igneous rocks (the lightest in color) are comprised mostly of quartz and potassium feldspar. Intermediate igneous rocks (somewhat darker than felsic) are made up of some quartz and potassium feldspar, but mostly plagioclase feldspar.
Continental plates are composed of mainly granitic rock.

Citrine is made up of a variety colors of quartz and topaz.
Silica or Quartz Crystal.
theprotoplasm of a cell is mostly made up of water.
Quartz is a natural form of silica, or silicon dioxide with the formula SiO2
Quartz will probably be found in most igneous and metamorphic rocks. Granite is a classic example of a rock with quartz in it. Search for images of "granite." Quartz sandstone is another rock practically made entirely up of quartz.
It was mostly made up of Greek people...
