This boundary is responsible for
sea-floor spreading
$100 Boundaries
What is Divergent
$200 Boundaries
This Boundary is responsible for
building mountains
$200 Boundaries
What is Convergent
$300 Boundaries
This boundary creates mid ocean
ridges and rift valleys

$400 Boundaries
This is the only boundary NOT
associated with volcanic
activity

$500 Boundaries
This is the only boundary to Have a
destructive effect on the Earth’s layers
$500 Boundaries
What is a Convergent Boundary
$100 Think “Layers”
The outermost rigid layer of Earth,
consisting of the crust and part of
the upper mantle.
$100 Think “Layers”
What is the
lithosphere
$200 Think “Layers”
What layer of the Earth does the letter D
represent?
$200 Think “Layers”
What is the
Inner Core
$300 Think “Layers”
What layer of the Earth does the letter A
represent?
$300 Think “Layers”
What is the crust
$400 Think “Layers”
What is the name for the part
of the mantle that is partially
molten
$400 Think “Layers”
What is the
asthenosphere
$500 Think “Layers”
Name the two layers of the
crust
$500 Think “Layers”
What are Oceanic and
Continental
$100 Lets get Movin’
A chain of undersea ridges
extending throughout all
the Earth’s ocean basins,
and formed by sea-floor
spreading.
$100 Lets get Movin’
What is a
mid-ocean ridge
$200 Lets get Movin’
The growth of a continent
along its edges is known
as what?
$200 Lets get Movin’
What is
Continental Accretion
$300 Lets get Movin’
The movement of one plate
downward into the mantle beneath
the edge of the other plate at a
convergent plate boundary.
$300 Lets get Movin’
What is Subduction
$400 Lets get Movin’
What is the accepted
primary mechanism
for sea-floor
spreading?
$400 Lets get Movin’
What are
Convection Cells
$500 Lets get Movin’
This is the field of study
of plate movements
$500 Lets get Movin’
What is Plate Tectonics
$100 Does it “Matter?”
Is the inner core liquid or
solid?
$100 Does it “Matter?”
What is Solid
$200 Does it “Matter?”
The outer core and the inner
core are both composed of
what two elements?
$200 Does it “Matter?”
What are Iron and
Nickel
$300 Does it “Matter?”
What happens to the
density of rocks as
they become more
interior to the Earth?
$300 Does it “Matter?”
What is it Increases
$400 Does it “Matter?”
This is a pattern of
movement in a fluid
caused by heating from
below and cooling from
above.
$400 Does it “Matter?”
What is
Thermal Convection
$500 Does it “Matter?”
This is the record of the past orientation
and polarity of the Earth’s magnetic field
recorded in rocks containing the mineral
magnetite.
$500 Does it “Matter?”
What is
Paleomagnetism
$100 Random
How old is the Earth?
$100 Random
What is 4.6 billion
years old
$200 Random
What is the name for the
supercontinent that existed
250 million years ago?
$200 Random
What is
Pangaea
$300 Random
What is the formula used to
calculate density?
$300 Random
What is
Mass/Volume
$400 Random
Why is the inner core solid and the
outer core liquid (molten)?
$400 Random
The pressure on the inner
core is greater
DAILY

Some rock sections found on
the ocean floor exhibit a
striped pattern. What is the
primary cause of the
pattern?
$500 Random
What are changes in the Earth’s
magnetic field strength and
direction

Wegener use to construct his Continental
Drift Theory?
What are the puzzle like fit
of continents and similar
fossils on different
continents
