Where does salt fall in the MOHs hardness scale?
where is rock salt on the moths hardness scale
What is the difference between dustless chalk and normal chalk?
* The particles of dustless chalk are very heavy and tend to fall directly to the floor instead of floating in the air, while the particles of the normal chalk floats in the air. * The dustless chalk writes smoothly without scratch, while the normal chalk leaves some scratches on the board. * The dustless chalk does not break easily while the normal chalk breaks easily.
Weathering abrasion example?

What is the rock hardness of obsidean?
Although technically it's not a mineral (but rather a glassy form of rhyolite containing predominantly orthoclase, quartz, and mica), obsidian would fall into the 5 - 5.5 range on the Mohs scale of hardness.
What is the Mohs hardness of obsidian?
Strictly speaking obsidian is not a rock as it is not composed of crystals so can't be mineralic! It is technically a volcanic glass. It's Moh's hardness is approximately 5-6 according to the Wikipedia entry for Obsidian although an exact value would depend on the exact composition of the Obsidian in question.
How is the Mohs scale of mineral hardness used?
The Mohs scale is used to aid in quick field identification of minerals, along with other techniques. Mohs based the scale on ten minerals that are all readily available. As the hardest known naturally occurring substance, diamond is at the top of the scale. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, and/or the softest material that can scratch the given material. For example, if some material is scratched by apatite but not by fluorite, its hardness on the Mohs scale would fall between 4 and 5. Hardness Mineral 1 Talc (Mg3Si4O10(OH)2) 2 Gypsum (CaSO4·2H2O) 3 Calcite (CaCO3) 4 Fluorite (CaF2) 5 Apatite (Ca5(PO4)3(OH-,Cl-,F-) 6 Orthoclase (KAlSi3O8) 7 Quartz (SiO2) 8 Topaz (Al2SiO4(OH-,F-)2) 9 Corundum (Al2O3) 10 Diamond (C)
