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.
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)
during heat prusure and time it changers from quartz to smoky quartz
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.

topaz
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
A penny has a Mohs hardness of around 3.5. This means that it can be scratched by harder materials like glass or quartz, but it can scratch softer materials such as chalk or talc.
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
no
nickel
It can be scratched by a diamond, corundum, topaz, and quartz.
The mineral that can be scratched by a penny is talc. Talc is the softest mineral on the Mohs scale, with a hardness of 1. A penny has a hardness of around 3.5 on the Mohs scale.
No, calcite is harder than a penny and cannot be scratched by it. Calcite has a Mohs hardness of 3, while a penny typically has a hardness of around 3.5 on the Mohs scale.

The scratch test can help distinguish gypsum from quartz. Gypsum is a soft mineral, so it can be easily scratched with a fingernail or with a knife blade. Quartz, on the other hand, is much harder and cannot be scratched with a knife blade.
The mineral that can be scratched by glass but not a penny is calcite. Calcite has a hardness of 3 on the Mohs scale, which is lower than the hardness of glass (5.5) but higher than that of a penny (2.5).
