Transcript

  • 1. Plate Tectonics How Land Moves and Builds
  • 2. Lesson Goal I will explain plate tectonic theory including uplift, volcanoes and earthquakes. I will demonstrate knowledge in my science notebook with definitions, illustrations, and question responses.
  • 3. Our Changing Earth So far, we have learned some ways the Earth changes naturally: Weathering Water Erosion Wind Erosion Extreme Weather
  • 4. Our Changing Earth This week, we will learn another way the Earth changes naturally: Plate Tectonics Let’s add this topic to our notebook (Don’t forget the Table of Contents)
  • 5. Plate Tectonics Let’s start with some new science words to add to our notebook: Write Vocabulary under the title Plate Tectonics, where we will be adding some new words as go
  • 6. Core: the solid rock, very hot center of the Earth
  • 7. Mantle: the layer of hot rock beneath Earth’s surface
  • 8. Crust: the outside, hard layer of the Earth
  • 9. Diagram Draw the diagram in your notebook. Be sure to label the parts we learned.
  • 10. Inside the Earth 1
  • 11. Inside the Earth 2
  • 12. Inside the Earth Check for Understanding Discuss with your table group On your note card, answer: 1. On which layer does erosion and weathering occur on Earth?
  • 13. I wonder how Earth’s layers relate to plate tectonics? Notes  Earth’s crust is broken into pieces, which “float” on the mantle layer  These pieces, called plates, are always moving, but very slowly  The plates move apart, collide into one another, and slide against other plates We’re going to need more vocabulary words
  • 14. Magma: melted rock found between the crust and mantle
  • 15. Tectonic Plates: massive pieces of rock under the land that fit together like a giant puzzle
  • 16. Continental Drift: when tectonic plates move, causing Earth’s continents to move with them
  • 17. Plate Tectonics
  • 18. Continental Drift Check for Understanding Discuss with your table group On your note card, answer: 2. What was Pangea?
  • 19. Continental Drift Check for Understanding Discuss with your table group On your note card, answer: 3. What caused Pangea to break apart?
  • 20. I wonder why this is important to Earth’s surface? Notes  When tectonic plates collide, it creates mountains and volcanoes  When tectonic plates move apart, ocean valleys are made  When tectonic plates slide against each other, earthquakes happen We’re going to need more vocabulary words
  • 21. Fault: the place where two plates touch
  • 22. Uplift: when plates collide and one is pushed upward, creating a mountain
  • 23. Folding: when a plate is squished between other plates and pushes up to form a mountain
  • 24. Mountains
  • 25. Inside the Earth Check for Understanding Discuss with your table group On your note card, answer: 4. Name two ways mountains are created with plate tectonics
  • 26. Lava: when magma reaches the Earth’s surface
  • 27. Volcano: a mountain formed by cooled lava from Earth’s mantle
  • 28. Volcanoes
  • 29. Diagram Draw the diagram in your notebook. Be sure to label the parts.
  • 30. Earthquake: when energy in the Earth causes plates to shift quickly
  • 31. Epicenter: the place where an earthquake began
  • 32. Magnitude: how powerful an earthquake is
  • 33. Earthquakes
  • 34. Plate Tectonics Check for Understanding Discuss with your table group On your note card, answer: 5. Name 3 ways plate tectonics creates landforms on Earth.
  • 35. Magic School Bus - Volcanoes
  • 36. Tsunami: A huge wave caused by an underwater earthquake or volcano
  • 37. Tsunamis
  • 38. Volcanic Island: An island created by the continual eruption of a volcano
  • 39. Volcanic Islands
  • 40. Types of Volcanoes
  • 41. Review with Final Quiz
  • 42. Lesson Goal I will explain plate tectonic theory including uplift, volcanoes and earthquakes. I will demonstrate knowledge in my science notebook with definitions, illustrations, and question responses.
  • 43. Exit Ticket I will explain ______ ____________ theory including ________, _________ and _____________.
