s.tectonic/tectonic-plates-earthquakes-and-volcanoes/
1. What phenomena would you expect to see at each of the three
different plate boundary types?
2. What do you notice about the distribution of volcanoes? 3. What do you notice about the distribution of earthquakes?
4. Explain how volcanoes, earthquakes, and plate boundaries are
related.
5. There are some volcanoes and earthquakes that are not located
at plate boundaries. How could you explain their locations?
3.1 Convection
• Describe how density plays a role in plate tectonics, both with
Convection 3.1
• Matching: Lithosphere, Aesthenosphere, Mantle, Oceanic Crust,
Continental Crust, Inner Core, Outer Core
1. The inner most layer of Earth’s interior
2. The thicker, less dense layer of Earth’s surface associated with
land
3. The layer above the inner core
4. The molten layer within Earth, above the core and below the crust
5. The cold, more dense rocky layer of Earth’s surface found beneath oceans
6. The semi-solid layer below the lithosphere that allows convection to occur
3.2 Plate Boundaries
• What are the 3 types of plate
boundaries?
• Can you list the features of each
(describe, characteristics and where they’re found)?
3.3 Volcanoes
• What are the 3 types of volcanoes? How are they
different?
• What is a substance’s resistance to flow? How does
this relate to how volcanoes erupt?
• How would you describe a caldera? How is it
different from a lava plateau?
• Where can you find the Ring of Fire? What kind of
3.4 Earthquakes
• Why do earthquakes occur?
• What are the three main ways that
3.4 Earthquakes
• Define the following parts of an earthquake
• Fault: _______________________________________
____________________________________________
• Focus: _______________________________________
____________________________________________
• Epicenter: ____________________________________
____________________________________________
• Which type of energy builds up as two plates grind past each
3.5 Seismic Waves
• This type of earthquake wave moves the fastest and arrives first
at a seismic station, but causes the least amount of damage. _____________________________________
• This type of wave moves a bit slower and arrives second at the
seismic station, causing a bit more damage than the first wave. _____________________________________
• This is the most destructive type of wave and only travels on
Earth’s surface: _________________________
• What is the name of the instrument that records earthquake
3.5 Seismic Waves
• What is the SP-Interval from the seismograph ? S ____ - P______ = ________min
• Using the S-P Time
interval from the previous question and the graph to the left, what is the
distance from the epicenter?
“A major 7.0 magnitude earthquake struck southern Haiti in Jan 2010, knocking down buildings and
power lines and inflicting a catastrophe for the Western Hemisphere's poorest nation.”
…However, a 7.0 magnitude has also hit California without causing as much
damage.
What is the thin, rocky, outermost
layer of the Earth
Layers of the Earth 100 question
The Crust
Layers of the Earth 200 Question
A 200
Which layer of the Earth is
solid and rocky but
semi-solid in some areas
due to high heat or low
The Mantle
This is the major source
of heat in the center of
Earth, made up of
iron-nickel
A 300
The Core
Layers of the Earth 400 Question
A 400
Which layer of Earth is
semi-solid, where
convection occurs,
Asthenosphere
This
specific
layer is made up
of both the crust and uppermost
mantle
A 500
Lithosphere
Convergent Boundaries100 question
B 100
Plates collide/come together
What 3 major geological features
are associated
with Convergent Boundaries?
1) Mountains
2) Volcanoes
3) Ocean Trenches
What affect do
Convergent
Boundaries have on
the
Lithosphere/plate?
Lithosphere is destroyed
What is the specific name
of the convergent boundary
where
oceanic crust is
forced beneath continental
crust
, and lithosphere is
destroyed?
Subduction Zone
Name at least one real world example of a convergent boundary.
Hawaiian Islands
Himalayan Mountains
Appalachian Mountains
Divergent Boundaries100 Question
C 100
Plates divide, split apart, separate
Divergent Boundaries200 Question
C 200
What is at least one major geologic
Oceanic Ridge
Rift Valley
New Seafloor
SURPRISE JEOPARDY!
What type of volcano typically has a shorter
lifespan with only 1 major eruption.
This volcano is smaller with steeper sides.
Divergent Boundary 300 Question
Cinder Cone Volcano
C 400
Divergent Boundary 400 Question
C 400
C 500
Divergent Boundaries 500 Question
JEOPARDY SURPRISE:
How does viscosity effect the size of a volcanic eruption?
More viscous lava will have a
more violent eruption, exploding upwards.
Less viscous lava will simply flow over
the volcano’s edge, producing no
major eruption

What plate movement do we see at transform fault boundaries?
D 100
Transform Fault Boundary 200 Question
