27. CONCLUSIONS
move apart
come together
slide past each other
28. Divergent Boundaries
• Plates are moving apart from each other
• We also term these sites spreading centers.
• Form what is known as a rift valley.
It is at divergent plate
boundaries where new
crust is created.
30. Convergent Boundaries
• Plates are pushing into neighboring plates.
• Usually a subduction zone occurs. That is
when oceanic crust crashes into and slides
under continental crust.
• 3 convergent boundaries can occur:
–continental/oceanic crust collision
–oceanic/oceanic collision
–continental/continental collision
36. Practice...
The wheels on the bus go
round and round
round and round
round and round,
The wheels on the bus go
round and round
all through the town.
37. Convection Cells
The mantle of the earth
Goes round and round,
Round and round
Round and round,
The mantle of the earth
Goes round and round
All underground
38. Spreading Centers

Spreading centers Rift Valley

39. Subduction Zones
When plates come together
One slides down, When plates come together
One slides down, One slides down,
One slides down. We call it a subduction zone.
40. Transform Fault
Plates slide past each
other at transform faults
Transform faults
Transform faults,
Plates slide past each
other at transform faults
and we live next to one!

52. TYPES OF FAULTS
• Normal fault: hanging wall moves down
relative to the footwall along divergent
boundary
• Reverse fault: compression causes the
hanging wall to move up relative to the
footwall
• Thrust fault: fault plane is a low angle or
nearly horizontal & hanging wall is pushed
up over rock
• Strike-slip fault: rock on either side of the
fault plane slides horizontally at transform
boundaries
70. P Waves
–Primary Waves (P waves): move fastest and are recorded first
• Can travel through solid & liquid
• Compression waves- cause the rock particles to move together & apart along
the wave direction
71. S Waves
– Secondary Waves (S waves): second to be
recorded
• Travel only through solid material: cannot be detected
on the side of the earth opposite the epicenter…Why?
Can’t go through the liquid of the earth’s outer core!
• Shear waves- cause rock particles to move at right
angles to the wave direction
