What is convection? Back to Board Vocabulary - $200 A measure of how much mass there is in a volume of a substance. What is density? Back to Board Vocabulary - $300 The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary. What is subduction? Back to Board Vocabulary - $400 Scientists who study the forces that make and shape the planet Earth. Who are geologists? Back to Board Vocabulary - $500 The process that continually adds new material to the ocean floor. What is sea-floor spreading? Back to Board Layers of the Earth - $100 This layer consists mainly of granite and basalt. What is the crust? Back to Board Layers of the Earth - $200 The part of the mantle that can bend like plastic. What is the asthenosphere? Back to Board Layers of the Earth - $300 Includes all of the crust and part of the mantle. What is the lithosphere? Back to Board Layers of the Earth - $400 The 6 layers of the earth from innermost to outermost. What are the inner core, outer core, mantle, asthenosphere, lithosphere, and crust? Back to Board Layers of the Earth - $500 The major difference between the inner and outer core. What is the inner core is a solid and the outer core is a liquid? Both are made of iron and nickel. Back to Board Heat Transfer/ Continental Drift - $100 The transfer of energy through empty space. What is radiation? Back to Board Heat Transfer/ Continental Drift - $200 This man proposed the theory of continental drift. Who is Alfred Wegener? Back to Board Heat Transfer/ Continental Drift - $300 DAILY DOUBLE!!! Heat Transfer/ Continental Drift - $400 The reason scientists rejected Wegener’s theory . What is he could not explain how Pangaea separated? Back to Board Heat Transfer/ Continental Drift - $500 The 3 types of evidence that Wegener used to support this theory of continental drift. What are landforms, fossils, and climate ? Back to Board Sea-floor Spreading - $100 This ocean is getting larger each year . What are the Atlantic Ocean? Back to Board Sea-floor Spreading - $200 The longest chain of mountains in the world. What is the mid-ocean ridge? Back to Board Sea-floor Spreading - $300 As oceanic crust moves away from the mid-ocean ridge, it becomes _________ and ___________. What is cooler and more dense? Back to Board Sea-floor Spreading - $400 The 3 types of evidence for Sea-floor spreading. What are molten material, magnetic stripes, and drilling samples? Back to Board Sea-floor Spreading - $500 Explain the steps involved in the continuous process of sea-floor spreading. What are convection currents in the asthenosphere, molten material erupting from the mid-ocean ridge, sea-floor spreads as material cools and becomes more dense, then denser material subducts back into the mantle? Back to Board Plate Boundaries - $100 The process that powers plate tectonics. What is convection? Back to Board Plate Boundaries - $200 The separate sections that Earth’s lithosphere is broken into. What are plates? Back to Board Plate Boundaries - $300 A place where two plates slip past each other. What is a transform boundary? Back to Board Plate Boundaries - $400 A rift valley forms when two continental plates ___________. What is diverge? Back to Board Plate Boundaries - $500 Label the following types of plate boundaries. C A B D F E A = divergent o/oE = convergent o/o B = convergent o/c C = transform D = divergent c/c F = convergent c/c Back to Board Daily Double • Specify Your Wager! Heat Transfer/ Continental Drift --The 3 things that cause convection currents. What are change in temperature, change in density, and gravity? Back to Board
