How would you characterize
this eruption?
What does that suggest
about the viscosity of the
magma?
Is this a relatively high- or
low-temperature magma?
Angle of slope?
What type of extrusive rock
would form here?
What type of intrusive rock
would form here?
What are examples of
minerals that would be found
in these rocks?
What minerals would not be
found in these rocks?
Where in the world do
volcanoes often occur?

• What is the relative
speed of this stream?
• How would you
characterize the
following features of the
sediment being
transported:
What’s
occurring at
this location?
What’s
occurring at
this location?
Why do these different
processes occur, and what is
the eventual result?

Sorting
Chemistry/mineralogy
• How would you measure
the discharge of this
stream?
• Where will these
sediments end up?
3
• How do we classify mass
movements? (3 criteria)
• What type of material
moved?
• In what manner did it
appear to move?
• How quickly did it move?
• What type of movement is
this?
• What chain of events may
have led to this movement?
• How exactly did water likely
play a role?
• What can humans do to
minimize such losses?
4
• What is the name of
this structural feature?
• What type of
deformation has taken
place here?
• Where in the earth did
this deformation
occur?
• What type of forces
were involved?
• If brittle deformation
had occurred instead,
what feature would
result?
• Where in the earth
would this
deformation occur?
• Where is the oldest
layer?
5
• How were these
layers originally
deposited?
• Where is the
youngest layer?
• What caused the
formation of the
canyon?
• How fast was/is the
river moving?
• Why are there
apparent ridges that
persist?
• What are the names
of other landforms
that form in this
way?
6
• What type of fault motion
has occurred here?
• What forces result in
such a motion?
• How can the magnitude
of the EQ be assessed?
• How will the epicenter be
located?
• Why can’t we predict
very well when the next
“big one” is coming?
• Where do earthquakes
tend to occur in the
world? Why?

Lessons from Day 1 (and hopes)
• You already know something about geology.
(Now you know much more, and in more
detail than before.)
• Geology is all around us. (You can provide
many examples and can explain them.)
• Geology has relevance to our lives and
surroundings. (You understand processes
well enough to support this statement.)
• There is a lot more to learn! (Still!)
