No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
during heat prusure and time it changers from quartz to smoky quartz
it depends on ehat kind of sentence it is in for example She scratched the her phone. (scratched a verb) in the sentence: He out the scrathed pocket in his pocket. (scratched is an adjective)
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
quartz
It can be scratched by a diamond, corundum, topaz, and quartz.

Quartz
Generally no; it's a handy field guide to try scratching crystals with a knife blade. Quartz isn't scratched, calcite is.
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
There is none because diamond is at the top of the scale so it can scratch anything.
from 1 to 10, talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, diamond. e.g hardness 6 will scratch or abrade apatite but will be scratched or abraded by quartz
