occurs when rock changes shape due to stress
the amount of force on a given area
bending of rock layers
Anticline, syncline, monocline
3 types of folds
upward arching fold; results from horizontal compression
downward fold; results from horizontal compression
folded rock layers with one incline or decline where both ends are horizontal;results from vertical compression
surface along which rocks break and slide past eachother
normal, reverse, strike-slip
3 types of faults
when the hanging wall moves down relative to the footwall; tension
when the hanging wall moves up relative to the footwall; compression
when the rocks break and the 2 halves move in opposite directions horizontally; results when force is applied from opposite directions
form at congruent boundaries; form when to continents collide and rock layers are squeezed together and pushed upward
form when tension causes large blocks of rock to drop down in relation to other rocks; tilting of rock layers can occur as tension pulls the rock layers apart
can form at convergent boundaries when the rocks that melted in subduction zones rises to earths surface and erupts to form a volcano
rising of parts of earths crust to higher elevations
crust coming back up to original elevation after a weight is removed
sinking parts of earths crust to lower elevations
forms when tension pulls plates apart creating a set of deep cracks
