What is the ten point scale of mineral hardness. It has diamond at 10 and talc at 1.

• A. Mohs Scale of Hardness
• B. 8
• C. 6
• D. 4

Answer: (A)

The Mohs scale of hardness is a simple, relative way to compare how hard minerals are by their ability to scratch one another. It runs from 1 to 10, with talc at 1 as the softest and diamond at 10 as the hardest. The idea is practical tests: if a mineral can scratch another, it’s harder; if it gets scratched, it’s softer. This naming, Mohs, is the standard reference for this scale, rather than just listing a number like 8, 6, or 4. Those numbers alone don’t identify the scale or its reference minerals.
