LAB 5:
EARTHQUAKES,
VOLCANOES
& MOUNTAINS
Key Question:
How are earthquakes,
volcanoes &
mountains related?
Think and Discuss:
1)Can ANY mountain have a
volcano erupt from it?
2)Do earthquakes & volcanoes
ALWAYS occur in the same
area?
3)Do earthquakes & volcanoes
ALWAYS occur at the same
time?
Vocabulary:
28. Latitude
Imaginary lines that run east/west and
measure north/south position
33. Longitude
Imaginary lines that run north/south and
measure east/west position
23. Depth
Vertical measure downward from the earth’s
surface
37. Magnitude
Power, the amount of energy released
43. Mountains
Any part of the earth higher than a hill (at
least 1000 feet)
56. Volcanoes
A vent in the earth’s surface where
magma/lava and ash erupt
In Lab 5, you will use
latitude & longitude
coordinates
to plot earthquakes &
volcanoes on a
world map showing
mountain chains.

related?
EARTHQUAKES, VOLCANOES & MOUNTAINS--
ALL OCCUR ALONG PLATE BOUNDARIES
EARTHQUAKES
OCCUR WHERE ROCK MOVES ALONG A FAULT
EX:
SAN ANDREAS FAULT
TRANSFORM PLATE BOUNDARY
MOUNTAINS
Are created at:
CONVERGENT PLATE BOUNDARIES
EX:
HIMALAYAS, INDIA
VOLCANOES
OCCUR:
at DIVERGENT Plate Boundaries
(MID-OCEAN RIDGES)
&
CONVERGENT Plate Boundaries
(SUBDUCTION ZONES)
Mid Ocean Ridge Volcano
DIVERGENT Plate Boundaries
Subduction Zone Volcano
CONVERGENT Plate Boundaries
The
GAS
CONTENT
of the
magma will
effect the
type of
volcanic
eruption
LOW GAS: CALM Eruption
HIGH GAS: POWERFUL Eruption
The exception…
Occur:
FAR FROM
Plate Boundaries
A
“HOT SPOT”
in the
MANTLE
burns
through the
CRUST
& forms a
VOLCANO
(MID-PLATE)
• The “HOT SPOT” does NOT move
• The CRUST above the Hot Spot moves
EX:
The HAWAIIAN
Islands
