Answer • Who is Harry Hess? $200 Sea-Floor Spreading The center of a Mid-Ocean Ridge. Answer What is a Rift? $300 Sea-Floor Spreading This geologist who named the process when new ocean lithosphere forms at a Mid-Ocean ridge when magma rises. Answer Who is Robert Dietz? $400 Sea-Floor Spreading Discovered in the 1960’s this evidence would support Sea-floor spreading Answer What is paleomagnetism? $500 Sea-Floor Spreading This rises and forms new ocean lithosphere. Answer What is Magma? $100 Paleomagnetism Residual magnetism of rock. Answer What is Paleomagnetism? $200 Paleomagnetism These are when the magnetic poles switch. Answer What are Magnetic Reversals? $300 Paleomagnetism This is when the magnetic minerals in rocks point magnetic North. Answer What is Normal Polarity? $400 Paleomagnetism This is the pattern scientist created to figure the polarity of rocks. Answer What is the geomagnetic reversal time scale? $500 Paleomagnetism This supported Hess’s theory by matching the magnetic reversals to the patterns of the sea-floor. Answer What is Magnetic Symmetry? $100 Plate Tectonics This is the upper layer of the mantle on the Earth’s crust. Answer What is the Lithosphere? $200 Plate Tectonics This form of crust is very dense and filled with iron and magnesium. Answer What is Oceanic Crust? $300 Plate Tectonics This is the amount of major tectonic plates scientist have found. Answer What is 15? $400 Plate Tectonics This is a sudden shift at a plates boundary. Answer What is a Earthquake? $500 Plate Tectonics This is the particular plate where the Pacific Ring of Fire is found. Answer What is the Pacific plate? $100 Plate Boundaries This is the line between plates. Answer What is a Plate Boundary? $200 Plate Boundaries The boundary where to plates move away from each other. Answer What is divergent boundary? $300 Plate Boundaries This is the boundary between two plates that are colliding. Answer What is a convergent boundary? $400 Plate Boundaries The boundary between plates that are sliding past each other horizontally. Answer What is a transform boundary? $500 Plate Boundaries Your Text Here Answer What is subduction? $100 Supercontinent Cycles This is a supercontinent that formed 300 million years ago. Answer What is Pangaea? $200 Supercontinent Cycles This is the ocean that covered most of Earth when Pangaea was present. Answer What is Panthalassa? $300 Supercontinent Cycles The process by which supercontinents form and break up. Answer What is the supercontinent cycles? $400 Supercontinent Cycles These two continents formed approximately 150 million years after the breakup of Pangaea? Answer What are Gondwanaland and Laurasia? $500 Supercontinent Cycles This formed when Laurasia drifted North and rotated slowly. Answer What is a rift? Final Jeopardy If continental drift plays out as it should this peninsula will end up in the current location of Alaska. Final Jeopardy Answer What is Mexico’s Baja Peninsula?
