Crust & Upper Mantle
The lithosphere is made up of
what two parts of the Earth?
$400
Iron
The core is made up of
mainly this element.
$600
Asthenosphere
What does the lithosphere
float on top of?
$800
It contains more iron and magnesium
Why is the mantle more
dense than the crust?
$1000
Lithosphere, Asthenosphere,
Mesosphere, Outer Core, Inner Core
Name the 5 layers of Earth
from the surface to the
center (based on physical
structure)

Alfred Wegener
What scientist first came up
with the idea of Continental
Drift?
$400
Pangaea
250 MYA there was a supercontinent on the Earth called
what?
$600
Because there was no mechanism for
movement
Why was the theory rejected
at first?
$800
Puzzle pieces, similar rocks on coast,
similar fossils on coasts, changing
climate
What 4 pieces of evidence did
Wegener have to support his
theory?
$1000
Laurasia & Gondwana
When Pangaea broke up it
formed what two continents?
$200
Mid-ocean ridges
Where does sea-floor
spreading take place?
$400
Magnetic minerals on the ocean floor
What is the evidence for
sea-floor spreading?
$600
When the magnetic poles change
places
What is a magnetic reversal?
$800
Centimeters
What units would you use
to measure the rate of seafloor spreading?
$1000
Molten rock contains metal minerals that
will align with the Earth’s magnetic field,
then cool and stay as a record of that time
How is a record of
magnetic reversals
recorded at mid-ocean
ridges?
$200
Oceanic & Continental
What are the two types of
tectonic plates?
$400
Convergent, Divergent, Transform
What are the three types of
plate boundaries?
$600
Because the atoms move farther away,
making it less dense that the
surrounding rock
Why does hot rock rise?
$800
Because oceanic lithosphere is more
dense than continental lithoshpere
Why does an oceanic plate
subduct below a continental
plate?
$1000
Ridge push & Slab pull
Other than convection, what
are two possible causes of
tectonic plate motion?
$200
Normal, Reverse (Thrust), &
Strike-Slip
What are the 3 types of
faults?
$400
Reverse or Thrust Fault
In what type of fault does the
hanging wall move up
relative to the footwall?
$600
Normal Fault
What type of fault occurs
because of tension?
$800
Left=footwall, Right=hanging wall
Look at the fault above,
which block is the footwall?
Which is the hanging wall?
$1000
Anticline
What type of fold is shown
below?
QuickTime™ and a
decompressor
