$200 The German scientist who suggested the theory of continental drift
$200 Who is Alfred Wegener? Scores
$400 Name 2 of the 4 pieces of evidence suggesting the continents used to be joined
$400 What are…? 1-fossil  2-shape of the continents 3-rock/glacial/salt deposits 4-alignment of mountain ranges Scores
$600 The name for the super continent that existed 250 million years ago
$600 What is Pangaea? Scores
$800 The main reason geologists did not believe him was because his theory was lacking this
$800 What is a satisfactory explanation of the force that pushes or pulls the continents? Scores
$1000 This was Wegener’s actual profession (was not a geologist!)
$1000 What is a meterologist? Scores
$200 These underwater formations form the largest mountain chain in the world
$200 What are midocean ridges? Scores
Daily Double
$400 At midocean ridges, lava erupts from the __________ and runs the length of a ridge
$400 What is the rift valley? Scores
$600 The age of the rocks on the ocean floor get progressively  ____________ the further away from the mid-ocean ridge.
$600 What is older? Scores
$800 The process of the oceanic plates moving away from the midocean ridges is known as this
$800 What is sea-floor spreading? Scores
$1000 Scientists are able to observe “stripes” in the ocean floor because these minerals freeze in different directions when the polarity of the planet changes.
$1000 What is magnetite or iron? Scores
$200 The process in which crust plunges back into the Earth is called this
$200 What is subduction? Scores
$400 Deep, V-shaped canyons that occur at areas of subduction
$400 What are trenches? Scores
$600 This is why oceanic crust is subducted under continental crust (also why older oceanic crust is subducted under newer crust)
$600 What is that it is more dense? Scores
$800 As crust is subducted, it melts into magma which may rise and eventually form these
$800 What are volcanoes? Scores
$1000 This is the deepest trench in the world
$1000 What is the Marianas trench? Scores
$200 There are these many major lithospheric plates
$200 What is 7? Scores
$400 This is the largest lithospheric plate
$400 What is the Pacific plate? Scores
Daily Double
$600 This method of heat transfer is the driving force behind the plate movement
$600 What are convection currents? Scores
$800 The Hawaiian Islands were formed by this
$800 What is a hot spot? Scores
$1000 This type of activity is found at all plate boundaries
$1000 What is earthquake (seismic) activity? Scores
$200 This is the type of boundary where midocean ridges form
$200 What are divergent boundaries? Scores
$400 The type of boundary formed by a lateral fault (plates grinding past each other in a horizontal direction)
$400 What is a transform boundary? Scores
$600 Los Angeles is found on this plate
$600 What is the Pacific plate? Scores
$800 This explains why a convection current works
$800 What is the deeper hotter mantle material rises (less dense) and then cools, becomes denser, and sinks? This cycle repeats. Scores
$1000 These islands are formed when two oceanic plates collide
$1000 What are island arcs? Scores
$200 Mountains only, no volcanoes, are formed at this type of convergent boundary
$200 What is a collision of two continental plates Scores
$400 This is the only country that has a divergent boundary running down the middle
$400 What is Iceland? Scores
$600 This is why there is no subduction at continental-continental collisions
$600 What is both plates are of very similar density? Scores
$800 The name for the earthquake and volcano zone that encircles the Pacific Ocean
$800 What is the Ring of Fire? Scores
$1000 This mountain chain is believed to have been formed when the North American plate converged with another continental plate during the formation of Pangaea.
$1000 What are the Appalachian Mountains? Scores
Final Jeopardy Scores The category is: Ancient Eruptions Final Jeopardy Question
Pompei and Herculaneum were devastated by the eruption of this legendary volcano in 79 A.D.
What was Mt. Vesuvius? Scores
