How do they form?
100
A naturally occuring , inorganic solid with a definite chemical composition and an orderly arrangement of atoms or ions.
What is a mineral
100
This pattern makes a crystal a crystal.
What is a repeating arrangement of atoms or ions in 3 directions.
100
these are long and typically have distinctly pointed ends
What are well formed quartz crystals
100
only 30 are referred to as this
What are the common rock forming minerals
100
Minerals can crystallize from either of these types of solutions
What are hot or cool solutions
200
Common household items used that are made from minerals
What is deoderant, shampoo, makeup, anything made from metal (belt buckles, jewelry or zippers)
200
To be a mineral, a solid must have this.
What is a crystal form.
200
a characteristic cube shape
What is a galena crystal
200
the two most abundant elements in the crust
What are oxygen and silicon
200
water/snow seeping into the ground, interacts with minerals in rocks and soil and picks up elements. These then become dissolved solids.
What is minerals that form from cool solutions, like halite or a coral reef.
300
quartz, feldspar and olivine are 3 of these.
What is rock forming minerals that occur naturally and are not made in a lab.
300
the formation of crystals is called
What is crystallization
300
these are somewhat diamond shaped and have sets of parallel sides
What are well formed calcite crystals
300
silicates and the nonsilicates are these
What are two main families of rock forming minerals
300
gold is an example of this kind of mineral formation.
What is minerals from hot solutions
400
any material made of 2 parts iron and 3 parts oxygen
What is hematite
400
Minerals can form from organic processes but are not considered this...
What is organic
400
most of the time they grow in tiny clusters
What are minerals
400
This is a member of the mineral group that has silicon and oxygen in its crystal structure.
What is a silicate
400
as lava or ash cools above ground or magma cools underground, atoms and ions arrange themselves and form mineral crystals.
What is minerals formed from magma
500
minerals composed of just one element
What is native elements like silver and sulfur
500
naturally occuring, definite chemical composition, crystalline form, solid, inorganic
What are the 5 main characteristics of a mineral.
500
Scientist use these to look at the atoms and ions in a crystal.
What are scanning electron microscope images
500
These are common nonsilicate minerals
What are calcite and halite
500
new minerals can also form from this...examples include metamorphic activity, unstable minerals combined with erosion cause minerals to break down.
What is changes in minerals
