What causes earthquakes to
occur?
•
Divergent Boundaries
•
Convergent Boundaries
•
Transform Fault Boundaries
•
Forces and Faults
Why/How do earthquakes
occur?
•
Pressure becomes to great
•
The rocks break at a weak
point
•
They break on a fault
•
Energy is released
Where does the energy
released go?
•
Energy is released at
the FOCUS (located in
the mantle or crust)
•
Energy spreads
outwards in all
directions
•
These vibrations are
called SEISMIC
WAVES
Where are the waves the
strongest?
•
The EPICENTER
•
The point on Earth’s
surface above the
focus
•
Energy is greatest
here!
Seismic Waves
•
Primary Wave (P - Wave)
•
Secondary Wave (S - Wave)
•
Surface Wave (L - Wave)
Primary Waves
•
Travel through ALL layers of the Earth
(solid and liquids)
•
Travel in a straight line (back and
forth)
Secondary Waves
•
ONLY travel through solids
•
Travel side to side and up and down
Slinky = Seismic Waves
•
You will use the slinkys
to demonstrate how the
waves move.
