    • Choose a category. You will be given the answer. You must give the correct question. Click to begin.
    • Click here for Final Jeopardy
    • Convection And the Mantle Sea Floor Spreading Plate-Tectonics 10 Point 20 Points 30 Points 40 Points 50 Points 10 Point 10 Point 10 Point 10 Point 20 Points 20 Points 20 Points 20 Points 30 Points 40 Points 50 Points 30 Points 30 Points 30 Points 40 Points 40 Points 40 Points 50 Points 50 Points 50 Points Drifting Continents Earth’s Interior
    • Holes drilled several kilometers into Earth’s crust provide direct evidence about Earth’s interior in the form of
    • Rock Samples
    • Geologists obtain indirect evidence about Earth’s interior by
    • Recording and Studying Seismic waves
    • What is the correct order (starting from the surface) of Earth’s layers?
    • crust, mantle, outer core, inner core
    • Earth’s inner core is what in structure?
    • a dense ball of solid metal.
    • Name This Layer And the sub layers
    • Mantle: Lithosphere, Asthenosphere, Lower Mantle
    • When you touch a hot pot or pan, energy moves from the pot to your hand. This is called
    • Heat transfer
    • The transfer of energy through empty space is called
    • Radiation
    • Heat transfer within a fluid takes place by
    • Convection Currents
    • When the heat source is removed from a fluid, convection currents in the fluid will
    • Eventually Stop
    • Earth’s magnetic field results from movements in the
    • Outer Core
    • According to Wegener’s hypothesis of continental drift,
    • the continents were once joined together in a single landmass.
    • What is Pangaea?
    • the name of the supercontinent that existed millions of years ago
    • Which type of evidences were used by Alfred Wegener to support his continental drift hypothesis?
    • Landforms, Fossils, Climate
    • Most geologists rejected Alfred Wegener’s idea of continental drift because
    • Wegener could not identify a force that could move the continents.
    • Any trace of an ancient organism that has been preserved in rock is called a
    • Fossil
    • What technology did scientists use in the mid-1900s to map the mid-ocean ridge?
    • Sonar
    • In sea-floor spreading, molten material rises from the mantle and erupts
    • Along Mid-Ocean Ridges
    • How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it?
    • by determining the age of rock samples obtained by drilling on the sea floor
    • What did scientists in a submersible see when they observed the mid-ocean ridge?
    • rocks formed by the rapid hardening of molten material
    • Most geologists think that the movement of Earth’s plates is caused by
    • Convection Currents in the Mantle
    • The geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion is the theory of
    • Plate-Tectonics
    • A place where two plates slip past each other, moving in opposite directions, is known as a
    • Transform Boundary
    • A rift valley forms at a
    • Divergent Plate Boundary
    • A collision between two pieces of continental crust at a converging boundary produces a
    • Mountain Range
    • The place where two plates come together is known as a
    • Convergent Boundary
    • Make your wager
    • What is happening at Z?
    • The edge of plate B is plunging beneath plate C and melting in the mantle.
