A 100 What is geology? A 100 These are the two forces that shape Earth’s landforms. A 200 What are constructive and destructive? A 200 These are the waves that are produced by earthquakes. A 300 What are seismic waves? A 300 These are the three main layers that make up the Earth’s interior. A 400 What are the crust, the mantle, and the core? A 400 This causes Earth’s magnetic field. A 500 What is the inner core spinning faster than the rest of the Earth? A 500 This is the movement of energy from a warmer object to a cooler object. B 100 What is heat transfer? B 100 These are the three types of heat transfer. B 200 What are radiation, conduction, and convection? B 200 This is an example of radiation. B 300 What is heat from the sun or heat from a fire? B 300 This is an example of conduction. B 400 What is a spoon heating up in a pot of soup? B 400 This is an example of convection. B 500 What is the movement of soup in a heating pot? (Heat moves up the middle, cools, and then moves down the inside edge of the pot.) B 500 This is the name for the supercontinent of all lands joined together. C 100 What is Pangea? C 100 This is the name of the scientist who developed the Theory of Continental Drift. C 200 Who is Alfred Wegener? C 200 Any trace of an ancient organism preserved in rock is called this. C 300 What is a fossil? C 300 DAILY Place A Wager DOUBLE C 400 These are three areas of evidence that support the Theory of Continental Drift. C 400 What are: Landforms Fossil Distribution Climate C 400 This is the scientific term for an educated guess. C 500 What is a hypothesis? C 500 This is the longest chain of mountains in the world. D 100 What is the mid-ocean ridge? D 100 This is the device that bounces sound waves off underwater objects. D 200 What is sonar? D 200 This is what sonar is used for. D 300 What is determining the distance to an object and mapping the ocean floor? D 300 These are the three types of evidence for sea-floor spreading. D 400 What are molten material magnetic stripes and drilling samples? D 400 This is the name for deep, underwater canyons. D 500 What are deep-ocean trenches? D 500 This is the name for the broken sections of the lithosphere. E 100 What are plates? E 100 These are the lines where different pieces of the lithosphere meet. E 200 What are plate boundaries? E 200 This is a deep valley that forms when two plates pull apart. E 300 What is a rift valley? E 300 This is a break in the Earth’s crust where rocks have slipped past each other. E 400 What is a fault? E 400 This is the boundary caused by plates moving apart. E 500 What is a divergent boundary? E 500 This is the boundary caused by plates moving together, or “colliding”. F 100 What is a convergent boundary? F 100 This is the boundary caused by plates moving past each other in opposite directions. F 200 What is a transform boundary? F 200 As the plates collide, this determines which plate comes out on top. F 300 What is density? F 300 This is the word for one plate moving under another. F 400 What is subduction? F 400 This landform is created when two continental plates collide. F 500 What is the formation of mountain ranges? F 500 The Final Jeopardy Category is: “Where will we be in another million years?” Please record your wager. Click on screen to begin This is how fast plates move.
