CH 10 - EARTH SCIENCE
THERE WAS ONCE ONE CONTINENT
SO WHY DO WE NOW HAVE MANY CONTINENTS?
CHANGING OF PLATES & MOVEMENT OF CRUST
WHAT KIND OF MOVEMENTS??
MAIN REASON STRESS
THIS PROCESS IS SLOW
THERE MUST BE PUSHING & PULLING
NAME THAT STRESS PUSHING & PULLING SIDEWAYS? SHEARING
NAME THAT STRESS CHANGING OR DESTRUCTION OF AN? DEFORMATION
NAME THAT STRESS PUSHING OF TWO SIDES TOGETHER? COMPRESSION
NAME THAT STRESS PULLING APART IN OPPOSITE DIRECTIONS? TENSION
NAME THAT STRESS BREAKING OF THE OBJECT…(LIKE YOUR LEG)? FRACTURE
FAULT STRUCTURE FORMED IN AREA OF EARTH THAT IS BREAKING APART
FAULTS THE SIDE OF THE BREAK THAT STAYS IN PLACE? FOOTWALL
FAULTS THE SIDE OF THE BREAK THAT MOVES? HANGING WALL
NAME THAT FAULT HANGIING WALL SLIDES DOWN? NORMAL FAULT
NAME THAT FAULT HANGIING WALL PUSHES UP? REVERSE FAULT
NAME THAT FAULT WALLS DO NOT MOVE UP OR DOWN… THEY TEAR ACROCC NORTH TO SOUTH? LATERAL FAULT
NAME THAT FAULT ________ ______I I_______ FAULT BLOCK MOUNTAIN
NAME THAT FAULT ______ _______ I_____I RIFT VALLEY
NAME THAT FAULT ____ _____ I_____I FOLDING CAUSED BY PRESSURE
NAME THAT FAULT ANT. ____ _____ I_____I SYN. ANTICLINE- TOP SYNCLINE- BOTTOM
FAULT OR FOLD? WHEN HEATED MELT LIKE CRAYONS? FOLD
FAULT OR FOLD? ROCK IS COOL AND SNAPS? FAULT

DOME UPLIFTED AREA CAUSED BY MAGMA
ISOSTASY BALANCE BETWEEN 2 AREAS EXISTS BETWEEN THE MANTLE AND THE CRUST
ISOSTASY CRUST MOVES ON LAYER OF MAGMA MOVING SLOWLY LIKE MOLASSES
