Thursday Sept 8th Warm-up Why is it important to learn about plate boundary movement?
2
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!
3
Bees! Come up and grab: White board Marker Paper towel to erase with Lets Review!
4
Divergent DEMO Draw table below on blank notebook page: What I saw… Observations..my teacher use… …my teacher do… …happen…
5
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
6
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
7
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!
8
Normal Faults occur at Divergent Boundaries
9
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
10
Let’s start with O-O What landforms are created as a result of an oceanic-oceanic divergent boundary?
12
O-O A rift valley (new crust) Volcanic Mid ocean ridge. Real world examples: The Mid-Atlantic Ridge Krafla Volcano(in Iceland)
13
C-C Landforms created?
14
C-C Rift Valley (new crust) Volcano Real world example: African Rift Valley
15
Friday September 9th Warm-up
16
Transform Boundaries
17
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.
18
Transform Boundaries Think-pair-share: What movement occurs at this boundary?
19
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?
20
Transform Boundaries What fault occurs? Not mine Not yours Options: Normal Reverse Strike Slip
21
Transform YES! Strike Slip Faults!
22
Where can this occur? Identify the three plate combinations! O-O C-C O-C Put in box ANY 2 PLATES!
23
What occurs at transform boundaries? EARTHQUAKES!!!! Real world example San Andreas Fault
24
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?
25
Homework! Boundary Song Take a slip before you leave. The rubric IS on my webpage under Homework and 1st Quarter Assignments. Due Tomorrow!!
26
Looking Deeper in to Faults
27
Boundary Comparison
