Minerals

say three ways to conserve minerals from the video

• Minerals must be used in a planned and sustainable manner.

• Technology should be advanced to use the low-grade ores efficiently.

• By not using them

What is the name of the mineral that leaves a white streak when scraped across a surface, used to make powder, and is known as the softest mineral on the MOHs scale?

• graphite

• talc

• gold

• fingernail

The five characteristics that all minerals share are:

• Definite Chemical Composition, Color, Density, Igneous, and Solid

• Definite Chemical Composition,  Crystal Structure, Inorganic, Naturally Occurring, and Solid

• Cleavage, Faces, Hardness, Metamorphic, and Streak

• Cleavage, Crystal Structure, Density, Igneous, and Solid
