Exploring Mineral Properties in Physical Geology

The video discusses various properties of minerals, including hardness, specific gravity, crystal shape, cleavage, color, taste, and magnetic behavior. The Mohs hardness scale is introduced, with examples like gypsum, talc, quartz, and diamond. Specific gravity is explained using galena and halite. Crystal shapes are highlighted with quartz, while cleavage is demonstrated with mica. Color variations in minerals are shown with muscovite and biotite. Taste is illustrated with halite, and magnetic behavior is demonstrated with magnetite and hematite.

What is the Mohs hardness scale used to measure?
