  • END OF UNIT FILING!

    BEFORE YOU DO ANYTHING ELSEPlease get your file folder off the back counter!!

    Then write your homework AND get your homework out to be checked!

  • WARM-UPWrite your homework leave it to be stamped!Update your Table of Contents for todays activities!

    Get your homework out to be checked!

    DateSession#ActivityPage#10/30 & 10/31 2Plate Tectonics Note Guide 3

  • IgneousMetamorphicSedimentaryWhere would you most likely find this type of rock?

    Where would you find?Where would you find?Based on how it is formed and where it is located, what information could you get from this type of rock?What info could you get?What info could you get?

  • QUICK REVIEWLayers of the EarthCrust (2 types)MantleOuter CoreInner CoreEarths crust and the very top of the mantle form the lithosphereLithosphere sits on top of the asthenosphere

  • HOW???

  • LAW OF UNIFORMITARIANISMLaw of Uniformitarianism: States that Earth is an always changing placeThe same forces of change are at work today that were at work in the past.Some changes are gradual; some changes are fast.

  • T-CHART: SLOW CHANGES VS. FAST CHANGES

  • SINKHOLEShttp://www.youtube.com/watch?v=RUjo3K_00tY

    Whether you categorize them as a fast or slow change, they seem to be getting more commonWHY?

  • SOME THINGS HAPPEN SLOWLY, WHILE OTHERS HAPPEN QUICKLY, BUT WHAT THEY BOTH HAVE IN COMMON IS THEY STEM FROM ONE COMMON MOVEMENT BUT MOVEMENT OF WHAT????

    HINT:

  • TECTONIC PLATESThe Lithosphere is broken into many large and small slabs of rock called tectonic plates and where two plates meet, a lot of changes can occur.

  • The plates move because of convection currents.The hot, soft rock in the mantle risesthen it cools, and sinks.

    TECTONIC PLATESHow do the tectonic plates move?

  • 1. Divergent2. Convergent 3. TransformTECTONIC PLATESThere are 3 types of plate boundaries

  • When one tectonic plate sinks under another plate

    IT CAN ONLY HAPPEN WHENContinental & oceanic plate collide = oceanic plate ALWAYS sinks because it is more DENSE.

    Oceanic & oceanic plate collide = the older more dense plate sinks!

    SUBDUCTIONWhat is SUBduction?

  • Key word: Divide

    DIVERGENT

  • DIVERGENT

  • What occurs at this boundary?New Crust FormsMid-ocean RidgesRift ValleysEarthquakesVolcanoes

    DIVERGENT

  • Key word: Collide

    3 types of convergent:Continental-continentalOceanic-oceanicOceanic- continentalCONVERGENT

  • CONVERGENT: CONTINENTAL-CONTINENTAL

  • What occurs at this boundary?High mountains Earthquakes

    CONVERGENT: CONTINENTAL-CONTINENTAL

  • CONVERGENT: OCEANIC-OCEANIC

  • What occurs at this boundary?Deep-ocean TrenchesVolcanic IslandsEarthquakes

    CONVERGENT: OCEANIC-OCEANICHawaii is NOT on a plate boundary!

  • CONVERGENT: OCEANIC- CONTINENTAL

  • What occurs at this boundary?Deep-ocean trenchesCoastal mountains (some are volcanic)Earthquakes

    CONVERGENT: OCEANIC- CONTINENTAL

  • Key word: Slide

    TRANSFORM

  • TRANSFORM

  • What occurs at this boundary?FaultsEarthquakes

    PLATE MOTION SIMULATION

  • HOMEWORK: REAL WORLD EXAMPLES & PICTURESYou can start by using the textbook/technology to search for a real-world example you can copy into your chart.

    When you go home, please print or draw a picture (drawings better be good!) to put in the box of that real-world example

  • WARM-UPWrite your homework leave it to be stamped!Update your Table of Contents for todays activities.

    Get your homework out to be checked!Get a whiteboard, marker and eraser off the back shelf, and get ready for a review!

    DateSession#ActivityPage#11/4 & 11/5 3Milky Way Plate Tectonic Lab (turn in for a formal grade and tape into page 4 when returned) 4Layers of the Earth Rap Lyrics/Continents Adrift Video Questions 5

  • REAL-WORLD EXAMPLESDIVERGENT BOUNDARYMid-Ocean Ridges like the Mid-Atlantic Ridge

  • REAL-WORLD EXAMPLESContinental-Continental ConvergentHigh Mountains like the Himalayas

  • REAL-WORLD EXAMPLESOceanic-Oceanic ConvergentDeep-ocean trenches like the Mariana Trench

  • REAL-WORLD EXAMPLESTransform BoundaryFaults, like the San Andreas Fault in California

  • WHITE BOARD QUICK TICKET REVIEWAnswer each question on the whiteboard ON YOUR OWN!

    I will come around and check your answers YOU GET ONE CHANCE, and if you are correct you will get a ticket!

  • ESSENTIAL QUESTIONS

    Draw and label the 4 main layers of the Earth:

    What were the 2 type of crust?

  • ESSENTIAL QUESTIONS

    Explain why the Earths interior is separated into these layers:

    DENSITY Materials they are each made up of The forces by which Earth was formed

  • ESSENTIAL QUESTIONS Which 2 layers make up the lithosphere?

    Which layer does the lithosphere sit on top of? Crust Mantle Asthenosphere

  • ESSENTIAL QUESTIONS Why is the inner core solid if it is so hot? Because it is under so much intense PRESSURE from the other layers sitting on top of it.

  • ESSENTIAL QUESITONS If new crust is created at divergent boundaries, then why doesnt Earth get any bigger? SUBDUCTION! As new crust is formed at a divergent boundary, old crust is being melted down at convergent boundaries where subduction is occurring. New crust is being created at the same rate that old crust is being destroyed.

    Earth recycles itself!

  • REVIEW: PLATE TECTONICSPlease turn to your Plate Boundaries Chart so you can reference it during the mini lab activity!

  • REVIEW: MILKY WAY PLATE TECTONICS LABWe will be doing a mini-lab with Milky Way bars to further demonstrate your understanding of plate tectonics and the features formed by plate movement.

    You must complete the lab guide and you must follow my instructions at all times!

    Make sure your lab guide is in the basket with your name on it at the end of the lab for a FORMAL grade!!

  • LAYERS OF THE EARTH RAPhttp://www.youtube.com/watch?v=Q9j1xGaxYzY

    Use as an example for your homework, listen and follow along with the lyrics while you eat your Milky Way bar!

    Brain Break!

  • CONTINENTS ADRIFTMOVIE QUESTIONS: Answer as you watch the movie cliphttp://www.youtube.com/watch?v=HrKTuCDierM

  • HOMEWORKRap, song or poem about Earths History material covered so far DUE NEXT CLASS!

    Start reviewing your vocabulary nightly!

  • WARM-UPWrite your homework leave it to be stamped!Update your Table of Contents for today! Put your rap, song or poem in the basket!

    Pick up the supplies on the front counter that are listed on the front whiteboard!

    DateSession#ActivityPage#11/6 & 11/7 4The Story of Earths History Foldable 6Sea-floor Spreading Lab 7HOMEWORK: Continental Drift/Columbian Exchange Article & Questions8

  • REMEMBERIt is the movement of the tectonic plates that cause the majority of changes on Earth.Some changes happen quickly, while others happen slowly, but none have been more Earth changing than thisHOW?

  • EARTHS HISTORY FOLDABLE Fold the 2 pieces of copy paper as shown. Label each flap as you see in the picture.

    The Story of Earths HistoryPangaea Continental DriftSea Floor Spreading & Magnetic Reversal

  • PANGAEAScientist Alfred Wegener noticed that Earths continents seemed to fit together like a puzzle, so he hypothesized that they were once joined in a single super continent called Pangaea

  • CONTINENTAL DRIFTThis led to his Theory of Continental Drift that although the continents were once joined, they slowly drifted apart!

    Wegeners Evidence:1. Matching rock layers on different continents

    2. Matching fossils on different continents

    3. Evidence of climate change tropical plant fossils in cold places, ice scratches in warm places

  • SEA FLOOR SPREADINGThe sea floor spreads apart at divergent boundaries and forms new crust as well as features such as Mid-Ocean ridges

    The rock closest to the crack is the youngest while the rock further from the crack is older

  • MAGNETIC REVERSALSMinerals in the magma that rises through the cracks in the sea floor align themselves with Earths magnetic poles (North and South)As the rock cools, the minerals stay fixed in this position, like a compassEarths poles periodically reverse. The stripes of rock along the ocean floor record these reversals.

  • SEA-FLOOR SPREADINGhttp://www.youtube.com/watch?v=GyMLlLxbfa4

  • SEA FLOOR SPREADING SIMULATION Read the Introduction to Sea Floor Spreading silently to yourself or with your partner. Quickly color & cut out your sea floor strip and tape the orange ends together 5 minutes!

    Cut Slits A, B & C as demonstrated!

  • SEA FLOOR SPREADING LAB Thread the blue ends up through Slit B from the bottomPull one side down through Slit A and the other down through Slit C Answer the questions on your lab guide
