of the explorer
who mapped out
he Grand Canyon
Who was John
Wesley Powell?
These are always
younger than the
rock layers around
them.
Extrusion, intrusion,
and faults.
These are the
process
responsible for
making the Grand
Canyon
Weathering ,
erosion, plate
tectonics,
converging plates,
ice, and volcanoes
This is younger than the other
layers.
The Fault labeled
Y.
This was a high, flat,
land formed west of
the Rocky Mountains
The Colorado
Plateau
This type of
rock is formed
from sediments
Sedimentary
Rocks
The rock that
responds to acid
by bubbling
because it has

What is

for rock layers
What is strata?

Colorado River
What is rough,
rigid, and
harder rocks?
Rocks made
from hardened
lava
What is
igneous
rock?
The remains
or imprints
of once live
organisms
What are
fossils?
The type of fossil
that is formed by
minerals absorbing
into the hard parts
of the organism and
turning it into rock
What are
petrified
fossils?
Organisms that
have been covered
by tree resin and
the resin hardens
overtime
fossilizing them
.
What are
fossils in
amber?
Fossils that are
widely distributed
and occurred for
only short periods
of time.
What are
index fossils?
Hollow
impression in
sediment that is
the shape of an

tell scientists
What kind of organisms lived I
the past.
How the organisms have
changed.
How the environment has
changed
A foot print,
animal burrows,
and caprolites
What are
examples of
Trace Fossils?
This is the age of
rocks when
comparing rock
layers
What is relative
age?
States that rock
layers on the
bottom are always
older that layers
above them.
What is the
Law of
Superposition?
The exact number
of years since the
rock has been
formed.
What is
absolute age?
Why index
fossil are so
important to
us.
They tell the
relative age of
rock layers
Characteristics of
an index fossil.
What are:
•Only occurred I
one time period.
•Widely
distributed?
Final Jeopardy
Place you bets?
This is what
geologists use to
study how old
something is and
how long ago
something
What is the
Geologic
Time Scale?
