A member of the mineral group that has silicon and oxygen in its crystal structure.
What is a Silicate
100
Molten rock stored beneath the earth's surface
What is Magma
100
Minerals that are composed of just ONE element (pg. 46)
What is a Native Element
100
This type of solution can dissolve more of a mineral.
What is a Hot solution
100
Rock that contains a high enough concentration of a desired substance, such as a metal, so that it can be mined for a profit.
What is Ore
200
When molten rock erupts on or near Earth's surface.
What is Lava
200
The repeating arrangement of atoms or ions in three directions.
What is a Crystal
200
This is how water can pick up minerals.
What is water can dissolve minerals as it moves over rocks and soil.
200
This is why streak is more useful for identifying metallic minerals than for identifying nonmetallic minerals.
What is Non-metallic minerals generally produce a white streak, so they could not be differentiated from each other. Many soft metallic minerals produce characteristic streak colors that could be used for mineral identification.
300
The way a mineral reflects or absorbs light at its surface.
What is Luster
300
This process occurs when particles dissolved in a liquid or a melt solidify and form crystals.
What is crystallization
300
Quartz, feldspar, and olivine are a few of these rock-forming minerals.
What is Naturally Occurring.
300
Occurs in a ratio of 1 part X to 4 billion parts rock in Earth's crust; lustrous yellow color with metallic properties; conducts electricity; does not corrode.
What is Gold
300
This is what happens when to magma when it cools.
What is atoms and ions arrange themselves to form mineral crystals.
400
The color of a mineral in powdered form.
What is Streak
400
The resistance of a mineral to being scratched.
What is Hardness
400
This is commonly mistaken for a mineral but is different because it is often made up of two or more minerals.
What is Rocks
400
This is a rare and attractive mineral that can be worn as jewelry.
What is a Gemstone
400
The reason it is often hard to identify minerals by their crystal structure.
What is because the crystals tend to grow in tiny clusters.
500
Minerals breaks and forms uneven surfaces.
What is Fracture
500
Minerals break with smooth, flat surfaces.
What is Cleavage
500
The five main characteristics used to determine if something is a Mineral.
What is naturally occurring, inorganic, solid, with a definite chemical composition and an orderly arrangement of atoms or ions.
500
The criteria used to identify a mineral.
What is Color, Luster, Streak, Hardness, Cleavage or Fracture, Density.
500
How do you know that silicon is one of the most abundant elements in Earth's crust.
What is because the majority of the most common rock forming minerals is Silicon, so it must be common in Earth's crust.
