Review game
1) Describe 2 pathways a sedimentary rock
can take to become an igneous rock
1) Melting- cooling
2) Heat/pressure-metamorphic rock-meltingcooling
2) What step in the rock cycle helps
metamorphic rock to form?
Heat & Pressure
3) Describe 2 pathways a igneous rock can
take to become a metamorphic rock
a) heat/pressure- metamorphic rock
b) Erosion- deposition- compactionsedimentary rock- heat/pressuremetamorphic rock
4) What step helps turn any kind of rock into
a sedimentary rock?
Erosion
5) A sedimentary rock
made up of rounded
fragments of other
rocks is called
A Clastic rock
6) What step in the rock
cycle would be
required to change
gneiss into
sandstone?
Erosion
7) A series of processes
on Earth's surface and
interior that slowly
changes rocks from one
kind to another is called
Rock cycle
8) The texture of a
metamorphic rock that
has grains arranged in
parallel layers is
described as
foliated
9) Where does the heat
that changes a rock
into metamorphic rock
come from
mantle
10)Rocks are changed
into metamorphic
rock through what
ways?
Heat & pressure
11)Rocks formed by
things that were once
alive are called what?
Organic rocks
12)How are clastic
sedimentary rocks
formed?
When sediments are compacted, and water
reacts with the chemicals in the minerals
making them stick together.
(cementation)
13)Describe the
process of
cementation as it
applies to
sedimentary rocks.
water reacts with the chemicals in the
minerals making them stick together.
14)Describe deposition.
When sediments build
up on top of each
other in one place
15)Describe erosion.
Process where rock is broken
down into smaller pieces
and transported to a
different location
16)Some igneous rocks
have a porphyritic
texture. Describe a
porphyritic texture.
Large grains scattered on a
background of much smaller crystals
17)What is the most
abundant intrusive
rock?
Granite
18)What is the most
abundant extrusive
rock
Basalt
19)Describe a coarse
grained rock.
Large easy to see
grains
20)How do geologists
determine a rock’s
texture?
Grain size, shape, and
pattern
21) A metamorphic rock
that has grains
arranged in bands is
said to be what?
Foliated
22)Give 2 examples of
a clastic rock.
Shale, conglomerate,
sandstone, breccia
23) Sandstone changing
to quartzite is an
example of what
process?
Metamorphism
(heat/pressure)
24) During the rock cycle,
forces inside Earth can
push rock down toward
the heat of the mantle,
and produce what type of
rock?
Metamorphic
