Which sample best shows the characteristics
normally associated with igneous rocks?
(1) A
(2) B
(3) C
(4) D
Intergrown

The photograph
shows an
igneous rock.
What is the origin and rate of formation of
this rock?
(1) plutonic with slow cooling
(2) plutonic with rapid cooling
(3) volcanic with slow cooling
(4) volcanic with rapid cooling
A geologist found a large quantity of mineral ore.
The mineral exhibited fracture, was harder than
glass, and had a metallic luster.
The mineral is probably composed mostly of
(1) NaCl
(2) FeS2
(3) SiO2
(4) PbS
Some of the bedrock in Vermont’s
Green Mountains is actually green in
color due to the presence of the mineral
chlorite. Which other mineral can cause
rocks to appear green?
(1) sulfur
(3) olivine
(2) magnetite
(4) halite
Which property is most useful in
distinguishing pyroxene from
amphibole?
(1) sample size
(3) type of luster
(2) hardness
(4) angles of cleavage
The table below shows some properties of four different minerals.
The minerals in the table are varieties of which mineral?
(1) garnet
(3) quartz
(2) magnetite
(4) olivine
Which three minerals contain high
concentrations of the element Calcium (Ca)?
(1) Sulfur, Fluorite, & Plagioclase
(2) Talc, Pyrite, & Muscovite
(3) Calcite, Amphibole, & Dolomite
(4) Potassium Feldspar, Halite, & Garnet
A series of layers (strata) of sedimentary rock have been
deposited over millions of years, as shown in the diagram
to the right.
If magma pushes its way to the surface, and heats rocks
along the way, many of these rocks will melt. The rest will
not melt however, and will instead undergo a contact
metamorphism.
How about here?
Quartzite!
Which rock will be created in the contact
metamorphic zone here?
Marble!
Under which crustal
temperature and
pressure conditions
will andalusite form?
(1) 300°C and 6000
atmospheres
(2) 600°C and 4000
atmospheres
(3) 500°C and 2000
atmospheres
(4) 700°C and 8000
atmospheres
Which graph
correctly
represents the
three most
abundant
elements, by
mass, in
Earth’s crust?
Rocks cannot be identified by physical properties like
minerals can. This is principally due to
1) The variety of minerals of differing properties that make them
2) The difference between the hardness of their forms
3) Their lack of properties
4) The manner in which their environment of formation effects them
Which processes formed the igneous rock
granite that is mined in Vermont?
(1) compaction and cementation of sediments
(2) cooling and solidification of magma
(3) uplift and weathering of bedrock
(4) application of heat and pressure to shale
Which rock was organically formed and
sometimes contains fossilized plant
impressions?
(1) rock gypsum
(3) breccia
(2) phyllite
(4) coal
In addition to ash,
solid rock formed on
Mt. Hekla from the
lava extruded during
an eruption. This
rock is most likely
Mt. Hekla
(1) light-colored metamorphic
(2) fine-grained igneous
(3) dark-colored metamorphic
(4) coarse-grained igneous
Base your answers to the questions on the
flowchart, which shows a sequence of
geologic processes at or near Earth’s
surface. Box A has been deliberately left
blank. The diagrams are not drawn to scale.
Identify the three
minerals that are
normally found with
quartz in samples of
andesite rock.
Plagioclase Feldspar
Biotite
Amphibole
Pyroxene
State one geologic
process represented
by box A.
Uplift
Weathering
Erosion
Identify by name one
type of rock layer,
other than sandstone,
shown in the outcrop.
Siltstone
Conglomerate
Limestone
Base your answer on the drawings of six sedimentary rocks labeled A through F.
Which table shows the rocks correctly classified by texture?
These strata represent ancient history. Many millions of years ago a
layer of siltstone and a layer of limestone were “intruded” by a felsic
magma that cooled into granite.
The granite intrusion
caused metamorphism
to part of the limestone.
What metamorphic
rock would be found in
this zone of contact
metamorphism?
(1) marble
(3) gabbro
(2) quartzite
(4) slate
Which intrusive igneous rock could be
composed of approximately 60% pyroxene,
25% plagioclase feldspar, 10% olivine, and
5% amphibole?
(1) granite
(2) rhyolite
(3) gabbro
(4) basalt

The diagram represents a sample of
mineral A.
Mineral A is most likely
(1) garnet
(3) olivine
