Question | Answer |
CONVECTION | circulation of material caused by differences in temperature and density |
COMPRESSION | stress resulting from squeezing |
SHEAR | stress resulting from parallel forces acting in opposite directions |
TENSION | stress that pulls something apart |
CONVERGENT PLATE BOUBDARY | where two plates collide |
DIVERGENT PLATE BOUNDARY | where two plates separate |
TRANSFORM PLATE BOUNDARY | where two plates slide by each other |
NORMAL FAULT | a fault in which the hanging wall moves down when compared to the foot wall; tension stress |
REVERSE FAULT | a fault in which the hanging wall moves up when compared to the foot wall; compressional stress |
STRIKE SLIP FAULT | a fault where two pieces of earths crust push past one another in opposite directions; shear stress |
OCEAN TRENCH | deep ,underwater trough created by one plate subducting under another plate at a convergent plate boundary |
SUBDUCTION | sinking of a denser plate below a more buoyant plate at a convergent plate boundary |
MID OCEAN RIDGE | mountain range located on the seafloor in the middle of the ocean |
FAULT BLOCK MOUNTAIN | parallel ridges that form where blocks of crust move up at faults |
FOLDED MOUNTAIN | made of layers of rocks that are folded |
UPLIFTED MOUNTAIN | forms when large regions rise vertically with very little deformation |
CONTINENTAL DRIFT | hypothesis that continents are in constant motion |
PLLATE TECTONICS | theory that earths surface is made of rock plates that move with respect to each other |
PANGAEA | ancient supercontinent, composed of land that forms todays continents |
SEAFLOOR SPREADING | new oceanic crust forms at a mid ocean ridge as old oceanic crust moves away |
