Transcript of "Elective Geography Secondary 3 Normal Academic (New)- Plate Tectonics 2"

  1. 1. + Elective Geog (New) Secondary 3 N Week 4: Living with Tectonic Hazards armanalluwie.blogspot.com
  2. 2. 2armanalluwie.blogspot.com
  3. 3. + 3 Feedback:Not a Natural Hazard http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=80058 armanalluwie.blogspot.com
  4. 4. + 4 Feedback: Natural Hazards  Definition  Naturally occurring event that threatens human lives and causes damage to property  Tectonic Natural Hazard  Caused by plate movements when continental crusts and ocean floors move  Eg. Earthquakes, volcanic eruptions and tsunamis  Climate Related Natural Hazard  Caused by severe and extreme weather and climate conditions  Eg. Drought, tropical cyclones and floods Highlight text on pg 5 of TBarmanalluwie.blogspot.com
  5. 5. + 5 How good are you with maps?  Refer to page 5 of your textbook  Using the map at the back of your textbook, identify locations of natural hazards and write them into the textbook.armanalluwie.blogspot.com
  6. 6. + 6 Natural Hazards occur everywhere. Some areas may be more prone to Natural Hazards. Impact of Natural Hazards depend on the where these Natural Hazards occur.armanalluwie.blogspot.com
  7. 7. + Elective Geog (New) Secondary 3 N Week 4: Living with Tectonic Hazards armanalluwie.blogspot.com
  8. 8. + 8 Lesson Outcomes  By the end of the lesson, we will be able to  Describe the internal structure of the Earth (core, mantle, crust) and tectonic plates  Explain the movement of platesarmanalluwie.blogspot.com

  12. 12. + 12  Compare your drawing with the one on page 6.  Have you seen this picture before?  Did you use any of the terms used in your textbook?  Draw a diagram showing the internal structure of the earth. Annotate the diagram using the terms listed below.armanalluwie.blogspot.com
  13. 13. + 13 Take note of the command words used!  Draw  Make a sketch of a geographical form  Include labels to the diagram  Question may be written as ‘Using a diagram’ or ‘Illustrate with a sketch’  Annotate  Add notes of explanation  Label with short comments a diagram, map or photograph to describe or explain  If asked ‘Using only an annotated diagram…’ only the diagram and attached notes will be marked  Insert/Label  Place specific names or details to an illustrative techniquearmanalluwie.blogspot.com
  14. 14. + 14 Internal Structure of the Earth: Core  Inner core- Solid  Pressure exerted on it by surrounding layers  1,200 km thick  Outer Core- Liquid  2,100 km thickarmanalluwie.blogspot.com
  15. 15. + 15 Internal Structure of the Earth: Mantle  Solid rock that flows under high temperature and pressure  Layer of solid rock and the asthenosphere  In the Asthenosphere, high temperatures and pressure bring the rocks close enough to their melting point for them to be easily deformed Solid rock that flows?armanalluwie.blogspot.com
  16. 16. 16armanalluwie.blogspot.com
  17. 17. + 17 Internal Structure of the Earth: Crust  Hard shell made up of thick slabs or rocks that are constantly moving  Plates  Oceanic Crust: crust beneath oceans  Continental Crust: crust beneath continents  Crust + Uppermost mantle = Lithosphere  Lithosphere melts, hot molten rock known as magma is formedarmanalluwie.blogspot.com
  18. 18. + Elective Geog (New) Secondary 3 N Week 5: Living with Tectonic Hazards armanalluwie.blogspot.com
  19. 19. + 19 Internal Structure of the Earth: Plates  Crust is broken into tectonic plates Type of Location Thickne Type and age of rock Crust ss Oceanic crust Beneath deep Between Consists mainly of basalt, a oceans 5 and heavy and dense rock formed 8km from magma which has coolded quickly Rock of less than 200 million years ago Continental Beneath the Between Consists of lighter rock, crust earth’s continental 30 and including granite land masses and 60km A wide range of rock ages, from under shallow very recent to nearly 4 billlion seas close to years old continentsarmanalluwie.blogspot.com

  25. 25. + 25 Worksheet 1.1: Tips and Tricks  Question 1  Must use information from the question  Question 2  Summarize figure 1.8 on pg 8  3 main points  Question 3  Too easy to give hints  Question 4  For the brave: Not taught yet, but can tryarmanalluwie.blogspot.com
  26. 26. + 26 Earth is made up of the core, mantle and crust. Oceanic crust is denser than a continental crust. Plate movement is caused by convection currents and slab- pull forcearmanalluwie.blogspot.com
