The Mohs scale of mineral hardness

The Mohs scale of mineral hardness is a simple way to compare how tough minerals are by testing if one can scratch another. Developed by Friedrich Mohs, it ranks minerals from 1 to 10, with talc at 1 (softest) and diamond at 10 (hardest). If a mineral can scratch another, it’s harder; if it gets scratched, it’s softer. This scale helps geologists identify minerals and understand their durability, providing a practical and straightforward measure of hardness based on common mineral comparisons.
