inorganic:
when a mineral cannot form from things that were once part of a living thing
crystal:
repeating pattern of a minera’s particles
streak:
color of a mineral’s powder
luster:
how light shines off a mineral
Mohs Hardness Scale:
ranking softest-hardest
cleavage:
when a mineral splits evenly
fracture:
when a mineral splits unevenly
geode:
a rounded hollow rock often lined w/ mineral crystals
crystallization:
the process which atoms are arranged to form in a crystal structure
magma:
molten material in the Earth
lava:
magma that reaches the surface
solution:
a mixture in which 1 substance is dissolved in another
color:
describes physical properties of a mineral; also the least helpful clue

mass in given space
NISCD:
No one in sumer cooks dinner
- Naturally Occurring -Inorganic -Solid - Crystal Structure
- Definite Chemical Composition
Hardness:
the best clues to identify a mineral
When liquid cools to a solid state,…
crystals form
Minerals form as:
1) as hot magma cools inside the Earth
2) when lava hardens on the surface
Crystallization can make minerals by:
1) Dissolved materials in water
2) of molten materials
Ores go through smelting by
the ore being mixed with limestone and other substances, then put into a blast furnace, which hot air melts the minerals, then it deposits the rest to the bottom of the furnace
Rocks make minerals, which makes rocks, which makes ____ _ ____`
ROCK N’ ROLL
Rock types:
igneous, sedimentary, and magma
vein:
a narrow channel or slab of a mineral that’s different from the surrounding rock
