Chapter 1 Movement of Earth’s Crust Pages D2-D28 Vocabulary 1. crust 2. mantle 3. core 4. lithosphere 5. asthenosphere 6. plate tectonics 7. divergent boundary 8. convergent boundary 9. transform fault boundary *now finish all 20 vocabulary words 10. mid-ocean ridge 11. rift 12. sea-floor spreading 13. earthquake 14. focus 15. epicenter 16. p wave 17. s wave 18. surface wave 19. Richter Scale 20. volcano a. composite b. cinder c. shield Earth’s Structure D6 9/27 Earth’s Layers 1. crust: Earth’s outermost layer 2. mantle: layer directly beneath crust 3. core: innermost layer D7 notes…. 4. asthenosphere: zone of weak, easily deformed rock in upper mantle 5. lithosphere: floats on asthenosphere and includes crust and upper part of the mantle Draw the “pie” on page D7..label vocabulary (# 1-5) from the notes..color nicely! Worth 10 points! Earth’s Plates D8 6. plate tectonics: theory scientists use to explain plate movement *tectonics comes from the Greek word “builder” Way cool!!! We are actually floating on these plates!! Questions of the week: please write a complete sentence!!! You will receive five points for writing a complete sentence (Capitals at the beginning of the sentence, and period at the end.) You will receive five points for a correct answer; you must use part of the question in the answer. 5 + 5 = 10 1. Is the core of our earth thought to be a solid or a liquid? 2. What is the difference between a model and an experiment? 5 minute video you can’t wait to see! http://www.youtube.com/watch?v=QDqskltCix A Changes to Earth’s surface D10-11 Erosion, deposition Water and wind erosion Rivers carry things and deposit Winds whoosh stuff around Glaciers carve out landscape Ka-BOOOOM! Meteors and comets whamming us! G.O. front page Lesson 1 Outermost 1. crust 2. upper mantle 3. lower mantle 4. outer core 5. inner core D11 1-5 dang, sentences only! 1. I have already drawn and labeled the layers of our Earth! 2. The lithosphere is __________ and ___________ and it floats on the asthenosphere. The asthenosphere is melted and moves the crust around. 3. find answer on page 8! 4. think and look at diagrams, if necessary 5. Write this in a complete sentence for full credit!! Don’t just write “A” or “B” or “C” or “D” 1. You have already done this! 2. The lithosphere is solid and cool, and the asthenosphere is like putty and warm. 3. The plates move on the lithosphere because underneath it is hot and moving. The Movement of Earth’s Plates 7. divergent boundary: where plates move away from one another < > 8. Convergent boundary: plates move toward each other > < 9. Transform fault: plates move past each other >>>> <<<< Let's zip to a cool website! Divergent boundaries D15 Plates moving away from each other < > 10. mid-ocean ridge: where most DB are found…chain of mountains on ocean floor DB..another slide! 11. rift = gap left where plates move apart…famous one = Great Rift Valley in Africa 12. sea-floor spreading: when magma rises up through cracks and creates new crust on ocean floor (YOU WERE THE NEW CRUST!) Convergent Boundary D16 10/3 >< colliding plates! Wham! *Example: Mariana Trench (6.8 miles deep) *Highest mountains = Himalaya Mountains 29,000 ft high *Andes Mountains = another example *80% volcanoes and 90% earthquakes occur at convergent boundaries http://www.youtube.com/watch?v=nfziy_860G U Arm Wrestling Contest 10/10/13 Mountain builder(win) Subducted(Lose) 1. Name of person you are challenging! a.(right) b.(left) 2. a. b. 3 a. Mountain or melted? MOUNTAIN??? / MELTED?? Challenge someone to an arm-wrestling contest..be sure to do BOTH arms!! Himalayas in Nepal Transform Fault Boundary D17 October 11 Plates scrape past one another *San Andreas Fault 5 centimeters/year 2 inches/year OR *earthquakes and mountains occur San Andreas fault (for two group points) #1 At what boundary is crust produced? #2…will crust be destroyed? #3 Along which boundary is crust neither formed or destroyed? #4 What happens when two oceanic plates collide? National Geographic: Moving Plates http://www.youtube.com/watch?v=KCSJNBM OjJs This is a 50 min. video..head’s up! Earth’s Surface Over Time D18 10/15/13 Pangea: 225 million years ago…continents all squished together to make a super continent! Pangea = “All Lands” in Greek http://www.youtube.com/watch?v=uGcDe d4xVD4 Are we still moving? You bet! Time for a worksheet! Answer the questions on the worksheet in a quiet, productive manner. We will be grading this either today or the next time I see you. Thank you for flying Woodland Middle School. Pangea Puzzles…must haves… 1. Master copy (“Cheat Sheet”) 2. Key with 4 symbols..your interests. 3. Put symbols all over your cheat sheet in bundles of 3 or more (so we can “cut” through them.) 4. Draw lines to create 7 puzzle pieces. Now trace on unlined paper, and cut out. Your name is on all 7 pieces. Place in ziplock bag. Worth 20 points!!! Due by Friday. Earthquakes and Volcanoes D22-29 Plate movements cause earthquakes • 95% earthquakes on/near faults (a crack in earth’s crust) Process of an earthquake 1. plates move but don’t slide freely 2. plates get locked up tightly 3. plates keep moving, so now pressure building up 4. plate bends and stretches until breaking point 5. rocks snap (BAM!) and shift to new position EARTHQUAKE HAPPENS NOW! Vocabulary! 13.earthquake = sudden jolt that releases energy as vibrations 14. focus = the point in Earth’s crust where the earthquake first started 15. epicenter = point on surface directly above the focus Richter Scale: gauges earthquakes 2.5 and below = really nobody felt it 2.5-5.4 = little bit of damage, stuff falls 5.5-6.0 buildings have damage 6.0-7.0 most buildings/damage 7.0-7.9 major damage/deaths 8.0 + total destruction Earthquake Measurement D24 19. Richter Scale: way to measure amount of energy released during earthquakes Question and Answer time: 1. If you were in an earthquake with a Richter number of 6.5, what is the damage? 2. Explain the difference between a P-wave and an S-wave. 3. What does the Richter scale measure? Quick look at earthquake map Please be patient while Mrs. B. locates this on her internet She IS trying, so give her credit. Don’t copy this: this ISN’T notes! Earthquakes in a week’s time…. How Volcanoes Form D25 20. volcano: mountain that may form around opening as lava/cinders build up Ring of Fire!!! 3 main types of volcanoes: (most occur at plate boundaries..FYI) *Composite Cone (Mt St. Helens) oozes and explodes *Shield Volcanoes: Hawaii, oozes and dome-shaped *Cinder Cone: violent, short eruptions (smaller volcanoes, too) Cinder cone that just “grew!” Hot Spot Volcano D28 Hawaiian islands have a hot spot Yellowstone has hot spots Occurs when there is a spot the magma has broken through lithosphere. Plate moves, but hot spot stays put. #2. Questions of the week Please use a complete sentence to receive full credit!!! 1. What does “tectonics” mean in Greek? 2. Using arrows or words, what do the plates of a convergent boundary look like? Answers “Tectonics” means “builder” in Greek. 2. A convergent boundary builds mountains, causes earthquakes and volcanoes. >< #3. Review the week questions. 1. What is a very clear example of a Transform Fault Boundary in California? Week #3 Questions of the week October 18 1. What is a great example of a Transform Fault boundary found in California? 2. What does “Pangea” mean in Greek? Answers: +2 for a sentence +3 for correct answer 1. The San Andreas Fault is a great example of a Transform Fault boundary. 2. “Pangea” means “all lands” in Greek.
