Halite can scratch gypsum, which has a Mohs hardness of 2.5 on the Mohs scale. Halite has a hardness of 2.5, so it can scratch any mineral with a hardness lower than 2.5.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
Quartz will scratch glass, as its hardness is usually around 7. Pyrite, on the other hand, has a hardness of 6 to 6.5, meaning it would not be able to scratch glass.
Fluorite would be able to scratch calcite but not apatite, as fluorite has a higher hardness than calcite but a lower hardness than apatite on the Mohs scale.
Halite, which has a Mohs hardness of 2.5, can scratch minerals that are softer than it on the hardness scale. This means it can scratch talc (hardness 1) and gypsum (hardness 2). However, it would not be able to scratch minerals like calcite (hardness 3) or any harder minerals.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
If you rubbed a mineral of hardness 7.5 against a piece of quartz, which has a hardness of 7, you would expect the harder mineral to scratch the quartz. The mineral with a hardness of 7.5 would leave a mark or scratch on the quartz surface, demonstrating the principle that harder materials can scratch softer ones. However, quartz would not be able to scratch the harder mineral in this scenario.
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
Quartz will scratch glass, as its hardness is usually around 7. Pyrite, on the other hand, has a hardness of 6 to 6.5, meaning it would not be able to scratch glass.
Halite, which is a form of rock salt, has a hardness of about 2.5 on the Mohs scale. Pearls, on the other hand, have a hardness of around 2.5 to 4.5, depending on the type and conditions. Given this range, halite may be able to scratch softer pearls, but it is more likely that pearls will resist scratching from halite. Generally, it's advisable to keep pearls away from harder materials to prevent any potential damage.
According to the scientificly accepted "Moh's Scale" Diamond would rank 1st.
Fluorite, which has a hardness of 4 on the Mohs Hardness Scale, can scratch calcite (hardness 3) but will not scratch apatite (hardness 5). Thus, fluorite fits the criteria of being able to scratch calcite while not being able to scratch apatite.
I would guarantee that diamond would scratch it, and types of corundum like rubies, sapphires and raw corundum probably would, because it is 9 on the moh's scale of hardness. Quartz, emerald, agate and topaz would also scratch it.
Fluorite would be able to scratch calcite but not apatite, as fluorite has a higher hardness than calcite but a lower hardness than apatite on the Mohs scale.
