The six physical properties of minerals What are luster, cleavage, fracture, streak, density, and hardness? The structure of a mineral What is crystaline? Scale that indicates a mineral’s resistance to scratching What is Moh’s Scale? One of the 92 smallest parts of a mineral that cannot be broken down into a purer substance What is an element? The ability of a mineral to resist scratching What is hardness? The way a mineral reflects light What is luster? The splitting of a mineral along smooth flat surfaces What is cleavage? The color of the powder of a mineral What is streak? The manner in which a mineral breaks along either a curved or irregular surface What is fracture? The ratio of the mass of a substance to the volume of the substance What is density? The number on the Moh’s scale for Talc What is one? The number on the Moh’s scale for a diamond What is ten? A mineral with a hardness greater than quartz (7) and less than a diamond would have this hardness What is 8 or 9? The hardness of a mineral that could not scratch or be scratched by Talc What is 1? A mineral that glows under ultra violet light is said to have this property. What is fluorescence? A mineral that fizzes or bubbles when a weak acid is placed on the mineral. What is chemical reaction? A mineral that causes an image to double What are optical properties? A mineral that attracts iron What is magnetism? A mineral that contains radium or uranium What is radioactivity? The last seismic waves to arrive and are most destructive What are surface waves? The fastest seismic waves. Arrive first and can move through solids, liquids and gases What are P waves? Seismic waves are the second to arrive and cannot move through liquids What are S waves? The place on the Earth that does not receive seismic waves What is the Shadow zone? The place between the crust and the mantle that causes seismic waves to increase in speed. What is the Moho Zone?
