simple.wikipedia.org/wiki/Mohs_scale_of_mineral_hardnessMohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.
en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardnessThe Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
geology.com/minerals/mohs-hardness-scale.shtmlWhat is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.
www.amfed.org/t_mohs.htmMohs Scale of Mineral Hardness. In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.
www.thoughtco.com/mohs-scale-of-hardness-607580The Mohs scale of mineral hardness is an ordinal scale that tests the hardness of minerals based on their ability to scratch softer materials. The Mohs scale runs from 1 (softest) to 10 (hardest). Talc has a Mohs hardness of 1, while diamond has a hardness of 10. The Mohs scale is only one hardness scale.
www.geologypage.com/2016/04/mohs-hardness-scale.htmlThe Mohs scale of mineral hardness is a qualitative ordinal scale that characterizes the scratch resistance of different minerals through the ability of a harder material to scratch a softer material. It was created by the German geologist and mineralogist Friedrich Mohs in 1812 and is one of several material science definitions of hardness ...
www.thoughtco.com/mohs-scale-of-mineral-hardness-1441189Mohs hardness scale was devised in 1812 by Friedrich Mohs and has been the same ever since, making it the oldest standard scale in geology.It is also perhaps the most useful single test for identifying and describing minerals.. You use the Mohs hardness scale by testing an unknown mineral against one of the standard minerals.
www.britannica.com/science/Mohs-hardnessMohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or
