Using Minerals
100
_______________ have shiny surfaces and don't let light pass through them. They are good conductors of heat and electricity
What is METALLIC MINERALS
100
naturally formed, inorganic solid that has a definite crystalline structure
What is MINERAL
100
the way in which a mineral reflects light
What is LUSTER
100
a measure of the ability of a mineral to resist scratching
What is HARDNESS
100
Does every type of mineral occur in every place on Earth?
What is NO
200
______________________ can have either shiny or dull surfaces, may let light pass through them, and are good insulator of electricity
What is NONMETALLIC MINERALS
200
a substance that cannot be separated or broken down into simpler substances by chemical means
What is ELEMENT
200
the color of the powder of a mineral
What is STREAK
200
fluorescence, magnetism, and radioactivity are examples of this
What is SPECIAL PROPERTIES
200
a natural material whose concentration of economically valuable minerals is high enough for the material to be mined profitably
What is ORE
300
Nonmetallic minerals that are highly valuable for their beauty and rarity. We use them in jewelry.
What is GEMSTONES
300
the smallest part of an element that has all the properties of that element
What is ATOM
300
the splitting of a mineral along smooth, flat surfaces
What is CLEAVAGE
300
the ratio of the mass of a substance to the volume of the substance
What is DENSITY
300
mining for mineral deposits located at or near the surface of the Earth
What is SURFACE MINING
400
Mineral that contains a combination of silicon, oxygen, and one or more metals
What is SILICATE MINERALS
400
a substance made up of atoms of two or more different elements joined by chemical bonds
What is COMPOUND
400
the manner in which a mineral breaks along either curved or irregular surfaces
What is FRACTURE
400
What scale is used to measure a mineral's hardness?
What is MOHS HARDNESS SCALE
400
mining for mineral deposits too deep to be surfaced mined
What is SUBSURFACE MINING
500
Mineral that does not contain compounds of silicon and oxygen
What is NONSILICATE MINERALS
500
a solid whose atoms, ions, or molecules are arranged in a definite pattern
What is CRYSTALS
500
What property of a mineral should you not use to identify it?
What is COLOR
500
The equation for density (think of the definition of density)
What is DENSITY=MASS/VOLUME
500
the process of returning land to its original condition after mining is completed
What is RECLAMATION
