Mohs scale is a qualitative ordinance scale i.e characterized by stretch-resistant minerals that are available through the hardness of science.
A mineral is pure samples of rocks. Its hardness is measured against the scale and as the properties of ordnance, scale measures the values from 1 to 10 in serial order of events.
LIner fashion of measurement is followed in Mohos and interatomic distance being measured also changes with the properties that best fit this pattern of alignments.
