TOPIC OUTLINE INTRODUCTION TO FOLDING AND FAULTING DIFFERENT TYPES OF FOLDS DIFFERENT TYPES OF FAULTS INTRODUCTION TO ROCK FORMATION TYPES OF ROCKS ROCK CYCLE
FOLDING AND FAULTING WHAT IS FOLDING? -Is the type of the earth m ovement resulting from the compression of rock because of high temperature and pressure from the interior of earth . -Bending, curving, crumpling, or buckling of rocks into folds are usually visible on rock strata. Folding can also happen in oceans and seas.
DIFFERENT TYPES OF FOLDS MONOCLINE one-sided slope connecting two horizontal or gently inclined strata
DIFFERENT TYPES OF FOLDS 2. ANTICLINE -an upward fold on the rock
DIFFERENT TYPES OF FOLDS 3. SYNCLINE -a downward fold on the rock
DIFFERENT TYPES OF FOLDS 4. OVERTURNED -happens when one-fold is pushed over the other limb due to increasing pressure
DIFFERENT TYPES OF FOLDS 5. RECUMBENT -an extreme type of overturned fold in which the axial plain acquires an almost horizontal altitude.
DIFFERENT TYPES OF FOLDS
FAULTING WHAT IS FAULTING? - Formation of cracks or fractures on the rocks.
DIFFERENT TYPES OF FAULTS NORMAL (DIVERGENT) FAULT- occur when rock is being pulled a part due to tension force. In this type of fault, rock generally moves down . REVERSE (CONVERGENT) FAULT- happens when rock is being squeezed due to compression force. This type of fault generally moves up. TRANSFORM (STRIKE-SLIP) FAULT- happens when rocks slide past each other in opposite direction. The San Andreas Fault is an example of this type.
