corundum, quartz, calcite, gypsum
Explanation:
The order of arrangement of minerals according to the moh's scale of hardness from hardest to softest is corundum, quartz, calcite, gypsum.
The moh's scale of hardness lists minerals in the order of their hardness.
Hardness is the resistance of a body or mineral to breakage. It is one of the physical properties used to identify substances.
The softest mineral according to the scale is talc and the hardest is gypsum.
- Talc
- gypsum
- calcite
- fluorite
- apatite
- orthoclase
- quartz
- topaz
- corundum
- diamond
The numbers indicates increasing order of hardness of the minerals.
We see that the order corundum, quartz, calcite, gypsum shows a decreasing hardness order.
