Warm-up
Why is it important to learn about plate boundary movement?
Divergent & Transform Boundaries Take out lab notebook Label Table of Contents:
Divergent Boundaries - 2 pagesTransform Boundaries - 2 pages
Cut out and glue in white notes pageDivergent 1st – skip a page!Transform 2nd
You have 3 minutes!!! READY, SET, GO!
Bees!
Come up and grab:White boardMarkerPaper towel to erase with
Lets Review!
Divergent DEMO
Draw table below on blank notebook page:
What I saw… Observations
..my teacher use…
…my teacher do…

Divergent Demo
What is inside this candy bar? What does each ingredient in the candy
bar represent?Think about what moves in a boundary…Chocolate = Earth’s CrustCarmel = asthenosphere
Divergent Boundaries
Think-pair-share- What kind of movement occurs?
In your own words: Discuss with a partner: What is a fault? Break in the rock of the crust where rock surfaces slip
past each other.
What type of fault occurs? Here are your choices:
Normal Reverse Strike Slip
Faults
Think back to yesterday….. If a reverse occurs at a Convergent,
THINK-PAIR-SHARE: predict which occurs at a DIVERGENT?
YESS!!! A normal Fault occurs! Lets check out some examples!
Normal Faults occur at Divergent Boundaries
Divergent Plate Combinations
Turn to your neighbor and name the two types of plates.Oceanic and continental
What 2 plate combinations can you make using oceanic and continental?O-OC-C
Let’s start with O-O
What landforms are created as a result of an oceanic-oceanic divergent boundary?
O-O
A rift valley (new crust) Volcanic Mid ocean ridge. Real world examples:
The Mid-Atlantic Ridge Krafla Volcano(in Iceland)
C-C
Landforms created?
C-C
Rift Valley (new crust) Volcano Real world example:
African Rift Valley
Friday September 9th
Warm-up
Transform Boundaries
Transform Boundary DEMO
Beetles:Pick up your tables index cards & Purple
directions 4 index card halves
2 card halves are cut straight2 card halves are cut jagged
Follow directions and answer questions in lab notebook.
Transform Boundaries
Think-pair-share: What movement occurs at this boundary?
LET’S DANCE!!
Doin’ the Boundary Bop! Find a partner! Listen as I call out a boundary!! When I say Convergent, how do you and
your partner move? Divergent? Transform?
Transform Boundaries
What fault occurs?Not mineNot yours
Options:NormalReverseStrike Slip
Transform
YES! Strike Slip Faults!
Where can this occur?
Identify the three plate combinations!O-OC-CO-C
Put in boxANY 2 PLATES!
What occurs at transform boundaries? EARTHQUAKES!!!! Real world example
San Andreas Fault
Reflection – Exit Ticket On the index card provided, reflect on the three
types of boundaries you have learned about. Include: How are they different? How are they similar? Combinations of plates (just oceanic, continental or
both?) Resulting landforms Two new terms you learned What surprised you? Analyze the DEMO’s we did. Were they good or bad?
Explain Why?
Homework!
Boundary SongTake a slip before you leave.The rubric IS on my webpage under
Homework and 1st Quarter Assignments.Due Tomorrow!!
Looking Deeper in to Faults
