Coal is a sedimentary rock formed
through
the cooling of magma, brought to the
surface through fissures.
compaction of limestone, where
interlocking crystals form underground.
Coal is a sedimentary rock formed
through
buried organic debris, compressed and
heated, leaving carbon behind.
A student analyzing an unknown rock
that formed on Earth's surface observes
that the rock has no layers, no individual
particles or crystal grains, and is smooth
and glassy. The unknown rock is most
likely classified as
intrusive igneous rock.
extrusive igneous rock.
intrusive metamorphic rock.
extrusive metamorphic rock.
The processes responsible for changing
sediments into sedimentary rock are
compaction and
intrusion.
cementation.
stratification.
foliation.
Which of the following properties of
minerals is described with the Mohs
scale?
hardness
luster
fluorescence
fracture
An unknown rock sample, X, formed from
weathering, erosion, and compaction.
Unknown rock sample X is.....
a metamorphic rock
a sedimentary rock
an extrusive igneus rock
an intrusive igneus rock
Which is NOT a property of rocks and
minerals that can be discovered by
looking at them?
texture
weight
color
luster
How are elements, rocks, and minerals
related?
Minerals are made of elements and
elements are made of rocks.
Elements are made of rocks and rocks
are made of minerals.
Rocks are made of minerals, and
minerals are made of elements.
Minerals are made of rocks, and rocks
are made of elements.
The process in which existing minerals
are changed into new minerals due to
the influence of extreme pressure or
temperature is called
deposition
evaporation
metamorphosis
crystallization
Listed below are six minerals along with their hardness as determined by the Mohs hardness scale:
Alabaster 2.0
Boracite 7.5
Creedite 4.0
Ekanite 5.5
Moissanite 9.3
Spectrolite 6.0
Using the list, which minerals will scratch Ekanite?
Boracite, Spectrolite, and Moissanite
Alabaster and Creedite
Boracite and Moissanite
Alabaster, Moissante, and Creedite
A pocket of melted rock, or magma, has
formed deep below the surface of Earth. After the pocket of magma slowly cools,
what does the magma become?
intrusive igneous rock
extrusive igneous rock
sedimentary rock
metamorphic rock
Metamorphic rock is formed by
compacting and cementing
melting and cooling
heat and pressure
erosion and weathering
Two minerals are the same hardness, color, and
luster. What other test can students do to help
identify the minerals?
They can rub the minerals on something hard to
see what color streak they leave.
They can shine light on the minerals to see how
much light they reflect.
They can rub the minerals together to see if one
will scratch the other.
They can drop the minerals to see how quickly
they break.
Limestone is a type of rock that can form in two
ways. It can either form from the accumulation of
shell and skeletal debris of ocean organisms, or it
can form when calcium compounds precipitate
out of ocean water and become cemented
together. Under which classification does
limestone belong?
igneous rock
silica rock
metamorphic rock
sedimentary rock
This picture shows a granite rock that was
sculpted into a statue. Granite is often used for
decoration and sculpting because the large
crystal formations are very beautiful. The large
crystals are formed when magma cools slowly.
marble
sedimentary
igneous
metamorphic
A student is investigating the properties of
several different minerals in order to identify
them. What is the best way for the student to test
the hardness of each mineral?
scratching it with different materials
hitting it with a hammer
eroding it with strong acid
chipping off a piece with a chisel
What type of rock is formed from the cooling of magma?
igneous rock
sedimentary rock
metamorphic rock
clastic rock
Diamond has a hardness of 10, a waxy luster, is
pale blue in color, and streaks white. Using this
information, why are diamonds widely used in the
construction industry?
A diamond's color can be used in paint to create
a pale blue color.
A diamond's luster makes it a good material for
use in windows.
A diamond's hardness makes it a good tool to
cut other materials.
A diamond's white streak can be used to make
marks on buildings.
