WARMER FLUID RISES AND COOLER FLUID SINKS CAUSING PLATE MOVEMENT
OUTERMOST ROCKY AND SOLID LAYER OF EARTH’S SURFACE, INCLUDES THE CRUST AND THE RIGID PART OF THE UPPER MANTLE
LAYER IN THE UPPER PART OF EARTH’S MANTLE MADE OF MATERIAL THAT CAN BE RESHAPED AND DEFORMED ON WHICH THE CONTINENTS MOVE
ANCIENT LAND MASS BELIEVED TO HAVE BROKEN UP TO FORM TODAY’S CONTINENTS
A LAYER OF EARTH’S SURFACE LYING JUST BELOW THE CRUST AND ABOVE THE INNER CORE
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
THEORY THAT DESCRIBES AND EXPLAINS THE WAY THAT CONTINENTS SEPARATED INTO TODAY’S LANDMASSES; ALSO, THE STUDY OF PLATES, THEIR MOVEMENTS, AND EARTH FEATURES
UNDERSEA MOUNTAIN RANGE THAT FORMS WHERE TWO PARTS OF EARTH ARE PUSHING APART
