What are metamorphic rocks
with stripes called?
foliated
What is the difference
between conglomerate,
breccia, limestone, and
sandstone?
Which of these would most
likely preserve animal
remains?
Granite, volcanic ash, schist,
or gneiss.
How does a sedimentary rock
become an igneous rock?
Conglomerate, breccia and sandstone are clastic
sedimentary rocks. Limestone is a chemical
sedimentary rock.
Volcanic ash. Granite is an igneous rock, while
schist and gneiss are metamorphic.
If sedimentary rock is exposed to enough heat it
will melt and become magma. When the magma
cools, it will become igneous rock.
Are basalt and obsidian
Both are extrusive. Basalt has a fine-grained
intrusive or extrusive igneous texture while obsidian is glassy in texture.
rocks?
Which of these is an organic
sedimentary rock…coal,
schist, gneiss or limestone?
Coal is organic in origin. It comes from plant
remains thousands of years old.
How do metamorphic,
sedimentary, and igneous
rocks form?
Igneous rock forms from cooled magma and lava.
Sedimentary is formed when eroded bits of rock
are compacted together. Both of these types can
be subjected to heat and pressure, which can
change the minerals in the rock, creating a
metamorphic rock.
Clastic means the rock is formed from eroded
bits of other rock. Non-clastic refers to a
chemical sedimentary rock, which forms when
minerals are left behind by evaporated water.
Slate, a metamorphic rock, is formed when shale
is squeezed.
What’s the difference
between clastic and nonclastic sedimentary rock?
Slate comes from what
sedimentary rock?

Know: granite is an intrusive
rock.
Name: ________________
Obsidian, pumice, basalt are extrusive rocks.
And…schist is metamorphic.
Contrast the cooling rates of
intrusive and extrusive rocks.
Marble forms from what
sedimentary rock?
Intrusive rocks form underground, where it takes
longer for the rocks to cool. This gives the rock
crystals more time to grow. Extrusive rocks form
on the Earth’s surface and therefore cool more
quickly.
Marble is a metamorphic rock formed from
limestone.
Know: sandstone,
conglomerate and siltstone
are clastic sedimentary rocks.
And once again…
Granite is an intrusive igneous rock.
