Plate-Doh Plate Tectonics

• 24 in Geology Binder

2
What landforms are created by the motion of the
lithospheric plates?

• Essential Question 3

3
Last week

• We defined plate boundary as the place where
  two lithospheric plates meet.
• We discussed what happens at the three types of
  plate boundaries.
• We created a color coded map showing the
  locations of each type of plate boundary.

OVERVIEW

• Goal To create models of landforms that are
  created at convergent plate boundaries.
• DAY ONE Construct two sides of a lithospheric
  plate boundary with your table.
• DAY TWO Draw a scale model of your plate
  boundary and label all features.
• DAY THREE Use notes and book to predict what
  features will be created at this convergence.
• DAY FOUR Create a model of these new features.

5
Creating your Lithospheric Plate

• DAY ONE

6
First

• Write your code, date, period, and 24 in upper
  right hand corner of your paper.
• Label this assignment Play-Doh Tectonics
• Make a key at the top of your paper. List the
  Play-Doh colors and what each color will
  represent.
• PINK upper mantle peridotite
• BLUE oceanic crust basalt/gabbro
• GREEN continental crust granite

7
With your table

• 1.) ? will obtain all supplies needed from Table
  1 (by the door).
• 2.) ? will use scissors to cut your square plate
  into two rectangles.
• 3.) ? will pair with ?, ? will pair with ?.
• 4.) With your partner, create a model of a plate!
• 5.) At end of period, ? will return all supplies
  to Table 1 and ? will carry play doh plates to
  the cubby.

8
With your partner

• ? / ? will create the upper mantle by covering
  the cardboard with pink Play Doh.
• ? / ? Add one flat continent (using green) over
  top of the upper mantle. It does not have to be
  in the middle of the plate!
• ? / ? Surround the continent with a thin layer of
  oceanic crust (blue). Oceanic and continental
  crust cannot overlap.
• ? / ? Add mountain(s) to the continent, and a few
  tiny (!) seamounts or tiny (!) mid-ocean ridges
  to the ocean.
• If time permits, begin (individually) creating
  scale model drawings of these plates (actual
  size!)

9
Illustrating your Lithospheric Plate

• DAY TWO

10
Today

• 1.) ? will go to cubby to get plates.
• 2.) At your table, put the plates together and
  decide where the top will be.
• 3.) Create a scale drawing.
• Take turns tracing BOTH plates, as they would fit
  together, leaving a gap between them.
• Label any geographic/geologic features and color
  your plates using colored pencils and your key.
  (Color your plate first, then trade with the
  other side of the table. )
• 4.) ? will put plates back in cubby.

11
Label the different types of convergent plate
boundary

• Label the parts of the line that are made with
  oceanic crust, and the parts with continental
  crust. Use C or O.
• Using a ruler, separate all the different types
  of convergent plate boundary.
• O/O Oceanic crust meets Oceanic crust
• C/C Continental crust meets continental
• O/C or C/O Continental meets oceanic (or vice
  versa)

12
Converging your Lithospheric Plate

• DAY THREE

13
Predict what will happen at each area!
14
Lets label each type of convergent plate
boundary with the possible outcomes
15
Oceanic vs. Oceanic Convergent Plate Boundary
16
Continental vs. Continental Convergent Plate
Boundary
EARTHQUAKES
17
Oceanic vs. Continental Convergent Plate

Your task
19
Millions of years have passed

• Imagine that you are hiking along your convergent
  plate boundary (North to South).
• Write a paragraph describing what types of
  convergent boundaries you encounter and what
  types of landforms you see at each.
• Use p34-35, 23, and 24.
• Draw and label a picture that supports this
  paragraph.

20
Staple all of your 24 together (key, drawing,
notes, paragraph, and NEW drawing)and pass to
the front.
