Plate tectonics Plate tectonics Presentation Transcript

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