false. if a mineral is harder than another mineral, it would be able to scratch the softer one
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
It means the mineral that scratches the other mineral is harder on the Mohs scale
False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
Most of the time, no. But there are some minerals, such as kyanite, that have more than one hardness in an individual crystal. But this is an exception to the Mohs scale of mineral hardness, which is based on the premise that a mineral of a lower number cannot scratch a mineral of a higher (harder) number.
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
A harder mineral will scratch a softer one.
false a mineral can not scratch any mineral harder than itself
No, it is just the opposite.
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
It means the mineral that scratches the other mineral is harder on the Mohs scale

Most likely you would be testing to see if the mineral was harder or softer than the nail.
In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
The hardness of a mineral is categorized on the Mohs hardness scale with talc as 1 and diamond as 10. A mineral can only be scratched bya mineral that is as hard or harder than the first mineral. So talc can scratch talc but nothing else. A diamond can scratch every other mienral including itself. Cordundum with a hardness of 9 can't scratch diamonds but can scratch a lot of other minderals.
