Faults are cracks or fractures in the Earth's crust caused by stresses that induce brittle deformation of rocks. There are three main types of faults: dip-slip faults which involve vertical motion, strike-slip faults with horizontal motion, and oblique-slip faults with an oblique motion. Normal faults occur during extension while reverse faults are caused by compression. The elastic rebound theory explains that tectonic plates accumulate energy during periods of stress until a sudden slip occurs along the fault, releasing energy in the form of seismic waves and causing earthquakes.

12. FAULTS
 FAULTS ARE ONE OF THE STRUCTURAL
FEATURES OF ROCKS
 WHILE ROCKS AT OR NEAR THE
SURFACE OF THE EARTH ARE COOL &
BRITTLE, ROCKS BELOW THE SURFACE
OF THE EARTH ARE HOT AND TEND TO
MOVE

13. FAULTS
 A LOT OF EXTERNAL FORCES ACT UPON
THE ROCKS AND CAUSE STRESS ON THEM
 DUE TO THIS STRESSES, ROCKS EITHER
UNDERGO DUCTILE DEFORMATION OR
BRITTLE DEFORMATION
 IF THEY UNDERGO DUCTILE
DEFORMATION, ROCKS DEVELOP FOLDS.
IF THEY UNDERGO BRITTLE
DEFORMATION, THEY DEVELOP FAULTS.

14. FAULTS
 FAULT IS DEFINED AS A SPLIT OR CRACK
OR FRACRTURE IN THE ROCK PRESENT
IN EARTH’S CRUST CHARACTERISED BY
RELATIVE DISPLACEMENT OF ONE SIDE
OVER THE OTHER.

 A FAULT LINE IS THE INTERSECTION OF
A FAULT PLANE AND EARTH SURFACE
 IT IS THE SURFACE TRACE OF A FAULT

20. TYPES OF FAULTS
 FAULTS ARE CLASSIFIED INTO THREE
TYPES NAMELY
 DIP SLIP FAULTS (VERTICAL MOTION)
 STRIKE SLIP FAULTS (HORIZONTAL
MOTION)
 OBLIQUE SLIP FAULTS (OBLIQUE
MOTION)

36. ELASTIC REBOUND THEORY
 The elastic rebound theory is an explanation
for how energy is spread during earthquakes.
As plates on opposite sides of a fault are
subjected to force and shift, they accumulate
energy and slowly deform until their internal
strength is exceeded. At that time, a sudden
movement occurs along the fault, releasing
the accumulated energy, and the rocks snap
back to their original undeformed shape.
