Question	Answer
because minerals do NOT come from once living material, they are said to be:	inorganic
in a mineral, particles line up in a repeating pattern to form a:	crystal
which one is used to determine color of a minerals powder- luster, cleavage, or streak	streak
Halite is a mineral formed through the evaporation of- magma, a solution, or lava	a solution
Minerals from which metals can be removed in usable amounts are called: ores, crystals, or gemstones	ores
A hollow rock lined with crystals is a	geode
Mineral deposits beneath Earth's surface that are different from the surrounding rocks are called	veins
Steel is an example of an	alloy
the color of a minerals streak is always the same? true or false	true
what are 2 ways minerals can form?	crystallization of magma, crystallization of minerals from solutions
minerals can form when magma cools beneath or when lava cool on the earth's surface? true or false	true
minerals can also form with they crystallize as a solution cools or evaporates? true or false	true
pure element	composed of atoms of a single element
most minerals are composed of a single element? true or false	false-most minerals contain at least 2 elements
luster	how the light is reflected
how can minerals be identified?	streak, color, luster, density, hardness, cleavage, fracture, crystal structure
cleavage	the way a mineral splits along even flat line
fracture	when a mineral doesn't split along lines, but rather breaks in jagged ways
are minerals naturally occuring?	yes
was any part of a mineral ever alive?	no
minerals have a definate volume and shape? true or false	true
can coal, which forms from the remains of plants, be considered a mineral?	no, because a mineral must be INorganic
for a substance to be a mineral it needs to have 5 characteristics-what are they?	naturally occurring, inorganic, solid, crystal structure, and definate chemical composition
geologist use what tool to measure density	a balance
density is mass divided by volume? true or false	true
test that describes the hardness of minerals	Mohs hardness scale
hardness can be determined by which test	scratch test
which mineral when frctured, looks like the surface of a seashell?	quartz
what describes how a mineral looks when it breaks apart in an irregular way?	fracture
what describes how a mineral looks when it breaks apart easily along a flat surface?	cleavage
there are some other special ways to identify some minerals-can you name 2?	fluorescence, magnetism
minerals can form from 2 things-what are they	magma or lava, and solutions
minerals can form ONLY on the earths surface? true or false?	false-they can form on and under the surface
name 2 useful ways minerals are used	gemstones, and metals
a soft mineral that is used to make powder	talc
how do we get metals from minerals?	they have to be mined, and then the metal removed from the mineral
name one mineral that can be mined and then sold	ore
anyone who searches for ore	prospector
how do miners know where to find the ore deposits in the earth?	geologists' map
what is the process called where ore is mixed with other substances and then melted to seperate the useful metal from the other elements	smelting
what do we call a solid mixture of two or more elements with characteristics of metal	alloy
give one example of an alloy	steel
if a mineral has a hardness of 5, and another mineral has a hardness of 8, which one could scratch glass?	8
what would be the best test to determine if a mineral you found was real or fake gold? color, streak, or luster?	streak-because pyrite (fake gold) has a different streak than real gold
