Quartz is a naturally occurring form of silica that often contains impurities.

no it doesnt
Regular beach sand is silica - mineral sand is like fine grained quartz.
Quartz movement is more traditional. Kintetic quartz relies on different principles and is a bit more accurate.
It is inorganic (does not contain carbon).
Fused silica is an engineering-quality, amorphous version of quartz. Source: http://www.makeitfrom.com/material-data/?for=Fused-Silica-Fused-Quartz
Quartz and glassy silica are both composed of the same elements in the same proportion. The difference is that in quartz is crystalline whereas glass is amorphous. This means that in quartz, the atoms are all ligned up in a regular repeating lattice. In glass, the atoms are arranged in a random way. This is analagous to the difference between a set of childrens blocks that have been stacked up nicely in regular rows, and blocks that are just dumped in a heap, and are arranged randomly.

Although gabbro is low in silica and has no quartz there are quartz gabbro's. Quartz gabbro's are thought to occur from magma that was over-saturated with silica.
Fine silica sand results from well weathered quartz.
No. Quartz is just crystalline silica. It does not have powers.
Silica
No, we call something mafic if it has a relative low silica content. As quartz is 100% silica, it's not mafic, but felsic.
Quartz is hard mineral consisting of silica. It is not plastic.
Quartz is formed from pure silica.
Silica is a mineral , that when is broken down by natural processes ( like erosion ), whether it be mechanical or chemical erosion, Becomes a consituant of clay, which is a classiication of soil species.
