Q:

How hard is granite on the Mohs hardness scale?

A:

Quick Answer

Granite is a 6 to 7 on the Mohs hardness scale. The Mohs hardness scale was developed by the German mineralogist Friedrich Mohs to determine the hardness of a mineral based on whether it can be scratched by a substance of known hardness.

Full Answer

The 10 standard minerals of the Mohs hardness scale from softest to hardest are talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum and diamond. The Mohs hardness scale is an excellent tool for identifying minerals. It is a comparative scale. Other methods are also used to identify minerals, such as luster, color, crystalline form and cleavage.

  • Q:

    What are some methods used in rock and mineral identification?

    A:

    Several methods exist to identify minerals, including the streak test, the Mohs hardness scale, the fracture test and the acid test. Based on these tests and the mineral's physical appearance, scientists can identify what the mineral is. Other methods, such as testing for specific gravity, require special instruments. Many of these methods are used in conjunction with one another.
