Transcript What is a fault?

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
1st – skip a page!
 Transform 2nd
 Divergent
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…
..my teacher use…
…my teacher do…
…happen…
Observations
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!!
