$200 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)

$200 Alfred Wegener What scientist first came up with the idea of Continental Drift?

$400 Pangaea 250 MYA there was a super- continent 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 sea- floor 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?

$200 Black What color shirt did Mrs. Harper wear yesterday?

$400 earthquakes What unit are we going to start on Thursday?

$600 Masquerade What was the theme of the Junior High dance last Friday?

$800 Black lab mutt What kind of dog do I have?

$1000 Columbus Crew Who is Mrs. Harper’s favorite soccer team?

Daily Double Laurasia & Gondwana When Pangaea broke up it formed what two continents?
