Sample Z is hard and composed of three materials
Which of the following is true of the objects?
Which of the following is NOT a property
Coal is a sedimentary rock formed
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
The processes responsible for changing
sediments into sedimentary rock are
Which of the following properties of

An unknown rock sample, X, formed from
weathering, erosion, and compaction.
Unknown rock sample X is.....
Which is NOT a property of rocks and
minerals that can be discovered by
looking at them?
How are elements, rocks, and minerals
The process in which existing minerals
are changed into new minerals due to
the influence of extreme pressure or

Listed below are six minerals along with their hardness as determined by the Mohs hardness scale:
Using the list, which minerals will scratch Ekanite?
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?
Metamorphic rock is formed by
Two minerals are the same hardness, color, and
luster. What other test can students do to help
identify the minerals?
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
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.
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?
What type of rock is formed from the cooling of magma?
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
