STRESS, FAULTS, AND FOLDS. Deformation is the bending, tilting, and breaking of the Earth’s crust. Plate tectonics is the major cause of crustal deformation.
Earthquakes The shaking of the Earth’s crust caused by a release of energy. The major cause is the build up of stress between two lithospheric plates.

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

FAULT OR FOLD? ROCK IS BRITTLE? FAULT

FAULT OR FOLD? QUICK STRESS? FAULT

FAULT OR FOLD? ELASTIC? FOLD

FAULT OR FOLD? SLOW PROCESS? FOLD

FAULT OR FOLD? PRESSURE? FOLD

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
