Earthquake
Ground shaking
Earthquakes.mov
Faulting
Fault_Lines_and_Earthquakes.mov
a break in a body of
rock along which one
block slides relative to
another


Fault blocks – blocks
on each side of the
fault
Hanging wall
Foot wall
- like a ramp
- hang from it
without
touching it
Faulting

Normal Fault
– rocks are pulled apart by
tension
What is this called for tectonic
plate boundaries?
Divergent
Faulting

Reverse Fault
– rocks are pushed
together by compression
What is this called for tectonic
plate boundaries?
Convergent
Faulting

Strike- Slip fault (shear)
– rocks are moved horizontally by
opposing forces
What is this called for tectonic plate boundaries?
Transform
What creates an earthquake

Plastic deformation –
cause rock to bend

Elastic deformation –
causes rock to stretch

Elastic rebound – causes
the rock to snap back

Earthquake!
Building of Mountains

Folded Mountains
– when rock layers are
squeezed together and
pushed upward
The Himalayas
Building of Mountains

Fault-Block Mountains
– When tension
causes rock to break
along a series of
normal faults, resulting
in different heights
Hanging Hills
Connecticut
Building of Mountains

Volcanic
Mountains
– along
convergent
boundaries
Baker Mountain,
Washington
