Chapter Three Vocabulary- Faults- Ruptures in the earth’s crust. Normal faults- move on a steeply inclined surface. Reverse faults- move rocks on the upper side of the fault up and over those below. Strike-slip faults- move horizontally as rocks on one side of the fault slip laterally past those on the other side. Elastic Rebound Theory- The theory applied to most earthquakes in which movement on two sides of a fault leads to bending of the rocks until they slip to release the bending strain during an earthquake. Stress- forces imposed on a rock Strain- change in shape of the rock in response to the imposed stress. Offset- the displacement of movement across the fault Surface rupture- is the total length of the break Creep- slow more or less continuous movement on a fault. Creeping faults either lack earthquakes or have only small ones. Blind Thrust- does not break the surface. Seismic waves- A wave sent outward through earth in response to sudden movement on a fault. (s and p waves)
