How do you identify the property of a mineral but what does it mean where we say calcite has a hardness?

We use Mohs scale of mineral hardness to access the hardness of minerals, which calcite is one example.

What color of streak is marble?
Marble, being composed almost entirely of the mineral calcite, would have a white streak. The same colour as calcite's streak.
What are the 7 properties mineralogist use to identify ninerals?
Colour - however, this can be a very misleading property. Transparency - Is the crystal transparent, translucent or opaque Lustre - how shiney is the crystal is, there are various different types of lustre. Hardness - Expressed in a number between 0 and 10 on the Moh scale. Streak - the colour of the mineral in powdered form. Easily testable by scratching the mineral on a porcelain plate. Cleavage - Very characteristic to a mineral is what the preferred cleavage is. Mode of occurrence - Is it like needles, fibre, tabular, prismatic, etc.
What is the difference between a scratch test and a streak test?
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
How is the value of a crystaline rock determined?
By levels of hardness, wear, scarcity, clarity and color, and association with other minerals. Also the habit of the mineral.
Which is the hardest mineral?
Diamond is the hardest mineral at Mohs hardness 10, ten being the hardest. There is no natural mineral substitute for processes requiring diamond. Diamond is four times as hard as corundum, the mineral constituting rubies and sapphires. Although diamond is the hardest naturally occurring mineral, it is easily fractured, a characteristic which allowed early jewellery makers to facet this crystal.
Does the Mohs scale help scientists identify the crystal shape of a mineral?
The Mohs scale is used to identify the mineral property of hardness only.
What is the most reliable physical property that can be used to identify a mineral?
HARDNESS
What will scratch calcite?
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
What mineral has a hardness of 2.5-3?
Calcite is a mineral that is white or colorless and has a hardness of 2.5 and splits with cubic cleavage.
Which object can scratch calcite but not apatite?
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
Is fluorite harder than calcite?
The mineral fluorite is harder than calcite. Fluorite is represented as a 4 on the Mohs scale of relative mineral hardness, calcite is a 3.
What is the mineral hardness of marble?
Marble isn't a mineral, but it is made out of around 100% calcite, which is typically 2.5 - 3 on Moh's hardness scale.
If a mineral scratches calcite but is scratched by apatite what is the minerals hardness?
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
Which mineral property is better for identifying a mineral Magnetism or hardness?
Hardness is better.
What does the property of mineral hardness measure?
Hardness measures a mineral's resistance to being scratched.
Which mineral had 4 directions of cleavage?
I think Calcite. Calcite is 3 on the hardness scale and sometimes you can break it into cubes. The difference between Calcite and Quartz is that Calcite is a milky white.
