Minerals Test Review
Question 1
 What
does inorganic mean?
 Something that does not arise from once
living things; not from the remains of
plants or animals
Question 2
 What
type of crystal system does halite
have?
 Cubic
Question 3
 What
is cleavage?
 The way a mineral breaks in straight lines;
a regular pattern that can be determined
Question 4
 True
or False: The faster the magma
cools, the larger the mineral crystals will
form.
 False; smaller crystals would form
Question 5
 What
does it mean when we say a mineral
always contains certain elements in
definite proportions?
 It has a definite chemical composition
Question 6
 Why
is coal not a mineral?
 It is made from the remains of plants and
animals
Question 7
 True
or false: An ore that is near the
surface is removed by strip mining?
 True
Question 8
 Most
minerals do not split apart evenly,
instead they have a characteristic type of
what?
 Fracture
Question 9
 A narrow
channel or slab of a mineral that
is different from the surrounding rock is
called a what?
 Vein
Question 10
 Magma
that cools deep within the Earth
forms minerals with what type of crystals?
 Large
Question 11
 A solid
 Alloy
mixture of two or metal is a what?
Question 12
 How
does halite form?
 From the evaporation of a water solution
Question 13
 Earthmoving
equipment strips away soil to
expose ore in what type of mining?
 Strip mining
Question 14
 What
is the softest mineral on the Mohs
hardness scale?
 Talc
Question 15
 Why
are metals useful as tools?
 Because they can be shaped easily, but
they are hard
Question 16
 Why
are cement, brick, steel, and glass
not considered minerals?
 Because they are man made (not naturally
occurring)
Question 17
 True
or false: The process of prospecting
involves mixing an ore with other
substances and heating the mixture to a
very high temperature.
 False; smelting is the process
Question 18
 True
or false: Iron is separated from
oxygen by cooling iron ore.
 F; heating not cooling separates them
Question 19
 What
is the repeating pattern of a
mineral’s particles called?
 A crystal
Question 20
 If
you broke a mineral into tiny pieces,
each piece would show what?
 The same crystal shape
Question 21
 What
is the term used to describe how a
mineral reflects light from its surface?
 Luster
Question 22
 What
is the hardest known mineral?
 Diamond
Question 23
 When
can minerals form on Earth’s
surface?
 When solutions evaporate
Question 24
 Which
type of mine often has a network of
tunnels that extend deep into the ground?
 Shaft mine
Question 25
 What
is the color of a mineral’s powder
called?
 Streak
Question 26
 What
is the term for a mineral that glows
under ultraviolet light?
 Fluorescence
Question 27
 How
do minerals form deep inside Earth’s
crust?
 By the crystallization of melted materials
Question 28
 What
is a rock called that contains a metal
or other economically useful mineral?
 An ore
Question 29
 What
type of mining involves digging a
huge hole?
 Open pit mining
Question 30
 True
or false: A mineral with a hardness of
6 will scratch a mineral with a hardness of
more than 6.
 False; less than 6
Question 31
 True
or false: The mineral quartz, which is
found in sand, is used to make glass and
electronic equipment.
 True
Question 32
 What
is a gemstone?
 A rare, hard, colorful mineral with a brilliant
or glassy luster
Question 33
 What
is a solid?
 A substance with a definite shape and
definite volume
Question 34
 What
does it mean we say that a mineral
must be naturally occurring?
 It forms by the process that shapes the
Earth; it is not man made
Question 35
 What
are the six crystal systems?
 Cubic
 Hexagonal
 Tetragonal
 Orthorhombic
 Monoclinic
 Triclinic
Question 36
 How
would we test to see if a mineral is
chemically reactive?
 By dropping an acid like vinegar or
hydrochloric acid on it to see if it fizzles
Question 37
 What
are the three ways that minerals
form?
 Crystallization of molten material
 Crystallization of hot water solutions
 Crystallization by evaporation of solutions
Question 38

are some of the special properties of
minerals?
 Fluorescence
 Chemical Reactivity
 Electrical Properties
 Radioactivity
 Double Image
Question 39
 Why
is color not the best way to identify a
mineral?
 Because minerals like quartz can come in
a variety of colors, and some minerals are
the same color as other minerals.
Question 40
