  1. CONVECTION CURRENT

  2. WARMER FLUID RISES AND COOLER FLUID SINKS CAUSING PLATE MOVEMENT

  3. LITHOSPHERE

  4. OUTERMOST ROCKY AND SOLID LAYER OF EARTH’S SURFACE, INCLUDES THE CRUST AND THE RIGID PART OF THE UPPER MANTLE

  5. ASTHENOSPHERE

  6. LAYER IN THE UPPER PART OF EARTH’S MANTLE MADE OF MATERIAL THAT CAN BE RESHAPED AND DEFORMED ON WHICH THE CONTINENTS MOVE

  7. PANGAEA

  8. ANCIENT LAND MASS BELIEVED TO HAVE BROKEN UP TO FORM TODAY’S CONTINENTS

  9. MANTLE

  10. A LAYER OF EARTH’S SURFACE LYING JUST BELOW THE CRUST AND ABOVE THE INNER CORE

  11. CONTINENTAL DRIFT

  12. HYPOTHESIS THAT CONTINENTS WERE ONCE PART OF A SINGLE LAND MASS THAT BROKE APART AND MOVED TO THEIR PRESENT POSITIONS—LED TO THEORY OF PLATE TECTONICS

  13. PLATE TECTONICS

  14. THEORY THAT DESCRIBES AND EXPLAINS THE WAY THAT CONTINENTS SEPARATED INTO TODAY’S LANDMASSES; ALSO, THE STUDY OF PLATES, THEIR MOVEMENTS, AND EARTH FEATURES

  15. MID-OCEAN RIDGE

  16. UNDERSEA MOUNTAIN RANGE THAT FORMS WHERE TWO PARTS OF EARTH ARE PUSHING APART
