Silence is most useful when broken.
The HELP strategy is most useful when you are making decisions.
Kimberlite is what geologists call "ultrabasic" rock because it does not contain quartz or feldspar. Those are the two most common rock-forming minerals.
Rose quartz is formed when a small amount of iron is incorporated into a pure quartz (SiO2) matrix. The inclusion of iron (Fe2O3) in many minerals s responsible for the colors that are observed. Iron also turns quartz into Amethyst.
Quartz is a natural form of silica, or silicon dioxide with the formula SiO2
While quartz itself doesn't have magnetic properties to make a compass, you could use a small piece of quartz as a reference point for direction when building a simple compass. By aligning the quartz with the Earth's magnetic field, you could use it as a marker to determine north and orient your compass accordingly.
Pieces of quartz free on the surface and not in the bed rock, as it has eroded from the a quartz vein and rolled and or washed to its current location.
Most sand grains are of quartz.

When quartz reacts with acid, it does not dissolve or react chemically. Quartz is a chemically inert mineral and is resistant to acids, including both weak and strong acids. This property makes quartz a useful material for various industrial applications.
Quartz is the rock most likely to be monomineralic, as it mainly consists of the mineral quartz.
Most of the quartz is extracted from open pit mines. Sometimes explosives are used to expose pockets of quartz
Quartz, being one of the most abundant rock forming minerals, is probably found in all states and in all countries. Most sand is comprised of small grains of quartz.
Quartz is a mineral- it does not grow. It is found in or near most places on earth.
The mineral that is most like quartz is chalcedony. Chalcedony is a type of cryptocrystalline quartz that exhibits similar physical and chemical properties to quartz, such as hardness and transparency.
Quartz is found in most places on earth since it is a mineral that is abundant.
Slow because Quartz is a very stable mineral at the Earth's surface and is very tightly bound giving it very unusual and useful properties.
