A quartz is a silicate and pyrite is a sulfide B quartz contains iron but pyrite does not C quartz is a silicate and pyrite is an oxide D quartz and pyrite both contain iron
Quartz is a crystal and when it is squeezed is vibrates at its resonate frequency which in turn is used by quartz clocks to keep time.
It is a piezoelectric crystal so its vibrations generate an oscillating electric field, which is amplified electronically to drive the clock.
-WHAT IS QUARTZ- Quartz is the second most abundant mineral in the Earth's continental crust (after feldspar). It is made up of a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an over
