True
100
What does it mean when we say minerals are "naturally occurring"?
They are not man-made, they can be found in nature
100
Name at least 4 properties used to identify minerals.
Color, streak, hardness, luster, cleavage/fracture
100
This type of rock forms from cemented shell fragments.
sedimentary rock
200
When rocks melt, they become ________.
magma or lava
200
What is compaction?
Process of pressing together sediments to form a rock
200
What is one use of graphite in schools today?
pencil lead
200
What is the chemical composition of a mineral?
It is what minerals are made up of.
It is the elements found in a mineral.
It is the mineral's chemical formula.These are found on pg. 16.
200
What is the difference between cleavage and fracture?
Cleavage breaks along smooth surfaces, fracture breaks randomly
200
Is halite a rock or mineral?
mineral
300
Describe how a metamorphic rock can become a sedimentary rock.
1. Uplift/weathering/erosion makes sediments
2. Sediments are deposited, buried, compacted, cemented into sedimentary rocks
300
What material do you get if you melt a metamorphic rock?
magma
300
What does "inorganic" mean?
Something that is not living or was never living or isn't made from living organisms
300
What is the composition of Quartz?
SiO2
300

This type of rock can form near volcanoes.
igneous rock
400
Process that causes igneous rocks to turn into metamorphic rocks
intense heat and/or pressure
400
Which statement is NOT true?
A. Cementation is a process that leads to sedimentary rocks.
B. When heat is applied to a rock and it melts, it may form a metamorphic rock.
C. A sedimentary rock in the future may change into another type of rock.
D. Solidification is always needed to form an igneous rock.
B. When heat is applied to a rock and it melts, it may form a metamorphic rock.
If you melt a rock, it becomes MAGMA.
400

Is coal considered a mineral? Provide ONE piece of evidence and be able to explain it verbally.
Not a mineral.
It is organic -- made from living things, and all minerals are inorganic.
