LESSON 5 Q2 Flashcards
causes rock to be pulled apart that result to lengthening and break apart
tensional stress
causes the rock to FOLD or FRACTURE. it squeeze together
compressional stress
happens when forces slide pass each other in opposite direction which result to slippage and translation
shear stress
formed when rocks experienced compressive stress and deformed plastically
folds
a simple bend in the rock layer where the oldest rocks are at the bottom and the youngest are at the top
monocline
fold that arches upward where the oldest rocks are found at the center of an anticline.
anticline
a rocks under ample stress can crack, or fracture
faults
the most common fault at divergent boundaries. in relation to the footwall l, it develops as the hanging wall drops down
Norma fault
fault most common at the convergent boundaries. forms when hanging wall move up
reverse fault
fault formed when the walls move sideways
strike slip fault
