Thursday Sept 8th 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 pages  Transform Boundaries - 2 pages Cut out and glue in white notes page  Divergent 1st – skip a page!  Transform 2 nd You have 3 minutes!!! READY, SET, GO!

Bees! Come up and grab:  White board  Marker  Paper 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… …happen…

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 Crust  Carmel = 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-O  C-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 straight  2 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 mine  Not yours Options:  Normal  Reverse  Strike Slip

Transform YES! Strike Slip Faults!

Where can this occur? Identify the three plate combinations!  O-O  C-C  O-C Put in box  ANY 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 Song  Take a slip before you leave.  The rubric IS on my webpage under Homework and 1st Quarter Assignments.  Due Tomorrow!!
