Plate tectonics

  1. 1. Plate Tectonics How Land Moves and Builds
  2. 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. 3. Our Changing Earth So far, we have learned some ways the Earth changes naturally: Weathering Water Erosion Wind Erosion Extreme Weather
  4. 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. 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. 6. Core: the solid rock, very hot center of the Earth
  7. 7. Mantle: the layer of hot rock beneath Earth’s surface
  8. 8. Crust: the outside, hard layer of the Earth
  9. 9. Diagram Draw the diagram in your notebook. Be sure to label the parts we learned.
  10. 10. Inside the Earth 1
  11. 11. Inside the Earth 2
  12. 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. 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. 14. Magma: melted rock found between the crust and mantle
  15. 15. Tectonic Plates: massive pieces of rock under the land that fit together like a giant puzzle
  16. 16. Continental Drift: when tectonic plates move, causing Earth’s continents to move with them
  17. 17. Plate Tectonics
  18. 18. Continental Drift Check for Understanding Discuss with your table group On your note card, answer: 2. What was Pangea?
  19. 19. Continental Drift Check for Understanding Discuss with your table group On your note card, answer: 3. What caused Pangea to break apart?
  20. 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. 21. Fault: the place where two plates touch
  22. 22. Uplift: when plates collide and one is pushed upward, creating a mountain
  23. 23. Folding: when a plate is squished between other plates and pushes up to form a mountain
  24. 24. Mountains
  25. 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. 26. Lava: when magma reaches the Earth’s surface
  27. 27. Volcano: a mountain formed by cooled lava from Earth’s mantle
  28. 28. Volcanoes
  29. 29. Diagram Draw the diagram in your notebook. Be sure to label the parts.
  30. 30. Earthquake: when energy in the Earth causes plates to shift quickly
  31. 31. Epicenter: the place where an earthquake began
  32. 32. Magnitude: how powerful an earthquake is
  33. 33. Earthquakes
  34. 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. 35. Magic School Bus - Volcanoes
  36. 36. Tsunami: A huge wave caused by an underwater earthquake or volcano
  37. 37. Tsunamis
  38. 38. Volcanic Island: An island created by the continual eruption of a volcano
  39. 39. Volcanic Islands
  40. 40. Types of Volcanoes
  41. 41. Review with Final Quiz
  42. 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. 43. Exit Ticket I will explain ______ ____________ theory including ________, _________ and _____________.
