Which physical property is shown by scratching one material with another?
Hardness
How do they polish gemstones and were?
A place where they process rough gemstones into finished product is called a Lapidary. Most gemstones are minerals and a harder mineral will cut a softer mineral , the hardest mineral is Diamond , so in a lapidary they use finely graded Diamond powder to carefully polish the softer surface of the gemstone.

What property is shown by the shape of the crystals in a mineral sample?
luster
How to determine if a mineral is a mineral?
Classifying minerals can range from simple to very difficult. A mineral can be identified by several physical properties, some of them being sufficient for full identification without equivocation. In other cases, minerals can only be classified by more complex chemical or X-ray diffraction analysis; these methods, however, can be costly and time-consuming. Physical properties commonly used are: * Crystal structure and habit: See the above discussion of crystal structure. A mineral may show good crystal habit or form, or it may be massive, granular or compact with only microscopically visible crystals.* Hardness: the physical hardness of a mineral is usually measured according to the Mohs scale. This scale is relative and goes from 1 to 10. Minerals with a given Mohs hardness can scratch the surface of any mineral that has a lower hardness than itself. * ** Mohs hardness scale: # Talc Mg3Si4O10(OH)2 # Gypsum CaSO4·2H2O # Calcite CaCO3 # Fluorite CaF2 # Apatite Ca5(PO4)3(OH,Cl,F) # Orthoclase KAlSi3O8 # Quartz SiO2 # Topaz Al2SiO4(OH,F)2 # Corundum Al2O3 # Diamond C (pure carbon) * Luster indicates the way a mineral's surface interacts with light and can range from dull to glassy (vitreous). ** Metallic -high reflectivity like metal: galena and pyrite ** Sub-metallic -slightly less than metallic reflectivity: magnetite ** Non-metallic lusters: *** Adamantine - brilliant, the luster of diamond also cerussite and anglesite *** Vitreous -the luster of a broken glass: quartz *** Pearly - iridescent and pearl-like: talc and apophyllite *** Resinous - the luster of resin: sphalerite and sulfur *** Silky - a soft light shown by fibrous materials: gypsum and chrysotile *** Dull/earthy -shown by finely crystallized minerals: the kidney ore variety of hematite * Color indicates the appearance of the mineral in reflected light or transmitted light for translucent minerals (i.e. what it looks like to the naked eye). ** Iridescence - the play of colors due to surface or internal interference. Labradorite exhibits internal iridescence whereas hematite and sphalerite often show the surface effect. * Streak refers to the color of the powder a mineral leaves after rubbing it on an unglazed porcelain streak plate. Note that this is not always the same color as the original mineral. * Cleavage describes the way a mineral may split apart along various planes. In thin sections, cleavage is visible as thin parallel lines across a mineral. * Fracturedescribes how a mineral breaks when broken contrary to its natural cleavage planes. ** Chonchoidal fracture is a smooth curved fracture with concentric ridges of the type shown by glass. ** Hackley is jagged fracture with sharp edges. ** Fibrous ** Irregular * Specific gravityrelates the mineral mass to the mass of an equal volume of water, namely the density of the material. While most minerals, including all the common rock-forming minerals, have a specific gravity of 2.5 - 3.5, a few are noticeably more or less dense, e.g. several sulfide minerals have high specific gravity compared to the common rock-forming minerals. * Other properties: fluorescence (response to ultraviolet light), magnetism, radioactivity, tenacity (response to mechanical induced changes of shape or form), piezoelectricity and reactivity to dilute acids.
How do you find the actual distance between two points on Earth using graphic scale?
You first measure the distance between the points as shown on the map, then you compare that measurement with the map scale.

Is it bad to boil mineral water?
No, it is not considered bad to boil mineral water. All boiling does is sterilize water, it has not shown to be harmful or to decrease the mineral effects.
What does Mineral Matter In soil mean?
Simple, Mineral matter is the mineral content shown in soil assays. Minerals like CaCO3 (calcium carbonate) etal.
