cleavage
Which statement about the formation of a rock is best supported by the rock cycle?
Sediment must be compacted and cemented before it can change to sedimentary rock.
Igneous rock must be melted and cooled before it can change to sedimentary rock.
Sedimentary rock must condense before it can change to metamorphic rock.
Sedimentary rock must cool before it can change to metamorphic rock.
Which of the following best describes the mineral composition of the rock?
The layers show that the rock was formed by one or more minerals that cooled very quickly.
The layers show that the rock was formed by a single element under high pressure.
The layers show that the rock was formed by a single element under extreme heat.
The layers show that the rock was formed by one or more minerals that compacted over time.
Josh noticed several cracks in the sidewalk. Weeds were growing through them, causing the cracks to expand. What process is this?
erosion
sedimentation
deposition
weathering
Which is the correct definition of a mineral's streak?
a line of ore in the mineral that is a different color
a crystal in the mineral that is a different color
the color of the powder a mineral makes
the color of the outside of the mineral
The diagram models a rock before and after undergoing some process. Which process is most likely modeled by the diagram?
Water weathering the rock, settling in the crack and freezing, then breaking the rock as it expands.
Winds weathering the rock, moving through the crack and causing the rock to break apart.
Gravity eroding the rock, pulling down on its particles and causing it to break apart.
Water eroding the rock, breaking down and carrying away loose rock particles.
Which would most likely increase erosion caused by a stream?
increased rainfall
decreased animal life
increased evaporation
decreased temperature
During a field trip to a Kansas state park, Uriah observes a rock in the shape of a mushroom, as shown. What is the most likely reason for the shape of the rock?
animals eroding the rock
wind weathering the rock
acid rain dissolving the hard parts of the rock
growth of small plants in the cracks of the rock
The diagram shows debris left in the path of a glacier. Which most likely describes the event in the diagram?
It is an example of erosion by wind.
It is an example of erosion by ice.
It is an example of physical weathering by water.
It is an example of physical weathering by gravity.
Rocks are broken down into smaller particles by which process?
erosion
weathering
conservation
decomposing
Granite cools very slowly from molten rock and therefore has very large crystals that are visible with the naked eye. Using this information, what is granite?
a metamorphic rock
an extrusive rock
a sedimentary rock
an igneous rock
Sandstone is formed when sand becomes buried under new layers of material and, over thousands of years, cements together to form rock. Sandstone can be classified as which type of rock?
igneous
metamorphic
sedimentary
volcanic
The 2 graphics show processes which change the surface of Earth. Which best describes the processes in the graphics?

Graphic X shows sediment being broken down through weathering, and graphic Y shows sediment being moved through erosion.
Graphic X shows rocks being broken down through deposition, and graphic Y shows sediment being moved through weathering.
Graphic X shows sediment being moved through weathering, and graphic Y shows rocks being broken down through sedimentation.
The picture shows a rock sample formed from a collection of rock particles that have been cemented together. Which type of rock is shown in the image sample?
igneous
metamorphic
sedimentary
volcanic
How are rocks most often classified?
by their age
by their mass
by their location
by their formation
Sedimentary rocks such as sandstone often contain cracks or ripples. These marks show that a number of sedimentary rocks form
in pockets of molten rock
inside ice in mountain ranges
under sands in the desert
at the bottom of bodies of water
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
extrusive metamorphic rock
intrusive metamorphic rock
extrusive igneous rock
intrusive igneous rock
Which processes lead to the formation of igneous rock?
heat and pressure
melting and cooling
erosion and weathering
compacting and cementing

igneous
metamorphic
sedimentary
sandstome
Which type of rock is formed by the cooling of magma?
metamorphic
sedimentary
igneous
classic
The minerals inside of some rocks will change under intense heat and pressure inside the Earth. Which type of rock will the changed minerals form?
igneous
sedimentary
metamorphic
basalt
Laura is comparing two minerals by shining a bright light on them and seeing how much is reflected off. What is Laura measuring?
color
streak
luster
hardness
How could a student figure out the hardness of an unknown mineral sample?
by observing whether the sample has the same streak as known samples
by observing how the sample bounces light from its surface
by observing what happens when the sample is put in water
by observing whether the sample can be scratched by known samples
