  2. Back Answer A1 Layer of earth made of hot, solid metals What is the inner core?

  3. Back Answer A2 The Earth’s thickest layer What is the mantle?

  4. Back Answer A3 The layer made of liquid metals that surrounds the inner core. What is the outer core?

  5. Back Answer A4 Earth’s crust and very top of the mantle together What is the lithosphere?

  6. Back Answer A5 A layer of hotter, softer rock in the upper mantle What is the asthenosphere?

  7. Back Answer B1 Hypothesis that Earth’s continents were once joined in a single landmass and gradually moved What is continental drift?

  8. Back Answer B2 This is what they called all of the continents joined as one huge supercontinent What is Pangaea?

  9. Back Answer B3 Huge underwater mountain ranges What are mid-ocean ridges?

  10. Back Answer B4 A circulation pattern in which material is heated and rises in one area, then cools and sinks in another What is convection current?

  11. Back Answer B5 It states that the Earth’s lithosphere is made up of huge plates that move over the surface of the Earth What is the theory of plate tectonics?

  12. Back Answer C1 A deep valley formed as tectonic plates move apart What is a rift valley?

  13. Back Answer C2 An area where a column of hot material rises from deep within a planet’s mantle What is a hot spot?

  14. Back Answer C3 This occurs where plates push together What is a convergent boundary?

  15. Back Answer C4 This is where two plates move apart, most are found in the ocean What is a divergent boundary?

  16. Back Answer C5 This occurs where plates scrape past each other What is a transform boundary?

  17. Back Answer D1 In the ocean, divergent boundaries are called this What is a spreading center?

  18. Back Answer D2 The process by which an oceanic tectonic plate sinks under another plate What is subduction?

  19. Back Answer D3 FREE SPACE You get the points

  20. Back Answer D4 A boundary along which two plates carrying continental crust push together What is continental-continental collision?

  21. Back Answer D5 A boundary along which a plate carrying oceanic crust sinks beneath a plate with continental crust What is oceanic-continental subduction?

  22. Back Answer E1 FREE SPACE You get the points!

  23. Back Answer E2 A thin layer of cool rock What is the crust?

  24. Back Answer E3 Large, moving pieces into which Earth’s lithosphere is broken What are tectonic plates?

  25. Back Answer E4 A switch in the direction of Earth’s magnetic field What is magnetic reversal?

  26. Back Answer E5 A boundary along which a plate carrying oceanic crust sinks beneath another plate with oceanic crust What is oceanic-oceanic subduction?
