This is the thin and
solid outermost
layer of Earth
Crust
This layer is liquid
metal
Outer Core
Outer part is solid
& rigid, but
becomes soft and
easily deformed
Mantle
This layer is solid
metal
Inner Core
This is the term
used to describe the
plastic-like part of
the Earth
asthenosphere
This is the name for
the supercontinent
that existed 300
million years ago
Pangaea
This was the scientist
who proposed the
Theory of
Continental Drift
Alfred
Wegener
Africa & South
America are the
best example for
this piece of
evidence
Shape of continents
fit together like
puzzle
Name two of five
early pieces of
evidence for
Continental Drift
1. Mesosaurus fossil
2. Shape of cont.
3. Glacial deposits
4. Similar rock
5. Migration patterns
One recent piece of
evidence for sea-floor
spreading is age of rock
near mid-ocean ridge.
This is the other one.
Magnetic
polarity bands
This is how many
major lithospheric
plates there are.
7
Water seeping into the ground
becomes heated by rock lying
above magma. ______ is
likely to occur when heated
water under pressure rises
back to surface through
fractured rock.
Geysers
This is made up of
the crust and upper
portion of the
mantle.
Lithosphere
The plates float on
this.
Asthenosphere
Name the three
geologic structures
that form as a result
of convergent
boundaries
Ocean trenches,
volcanoes, and
mountains
The machine that
measures the
movements of an
earthquake
Seismograph
The Richter
scales measures
the ___ of an
earthquake.
Magnitude
These waves arrive
second at a
recording station.
S-waves
These waves can
only travel
through solids.
Surface
waves or SWaves
P-waves are also
known as this.
Longitudinal
waves
This is the exact
point where an
earthquake
originates
Focus
Seismic waves slow
down once they
reach this layer of
the Earth
Outer Core
These are the two
ways that thermal
energy is
transferred through
Earth
Conduction and
Convection
When 2 lithospheric
plates move apart, it
is called this type of
boundary
Divergent
boundary
Name 2 items
that form at a
divergent
boundary
Rift Valley, Ocean
Ridge, Volcano, or
New Sea Floor
This is why
fossils are good
indicators of
relative age
They occur for
well defined
period of time
This is the process
that scientists use
to determine
absolute age
Radioactive Dating
This is the
principle that says
rocks layers are
laid down
horizontally
Original
Horizontality
Rocks that are on the
bottom of a sequence
are _______ than the
rocks on the top of the
sequence.
Older
Which
layer is
younger:
A or B?
Why?
B, because of
intrusion
Name at least 3
famous phrases that
Mrs. Witting always
says in class
Let’s go Schomoes,Wa-Wa, I
gotta laugh because otherwise I’ll
cry,
