Transcript

  • 1. + Elective Geog (New) Secondary 3 E Week 3: Living with Tectonic Hazards armanalluwie.blogspot.com
  • 2. + 2 Lesson Outcomes  Students would be able to  Describe the internal structure of the Earth (core, mantle, crust) and tectonic plates.  Explain the movement of plates.armanalluwie.blogspot.com
  • 3. 3 http://www.youtube.com/watch?v=TzzGPfVx32Marmanalluwie.blogspot.com
  • 4. + 4  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
  • 5. + 5 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
  • 6. + 6 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
  • 7. + 7 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
  • 8. 8armanalluwie.blogspot.com
  • 9. + 9 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

  • 14. + 14 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
  • 15. + 15 Internal Structure of the Earth: Plates  Crust is broken into tectonic plates Type of Location Thickne Type and age of rock Crust ss Oceanic Beneath deep Between Consists mainly of basalt, a crust 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 30 and including granite continental land 60km A wide range of rock ages, from masses and under very recent to nearly 4 billlion shallow seas years old close toarmanalluwie.blogspot.com continents
  • 16. 16armanalluwie.blogspot.com Class Discussion: Convection Currents/ Slab Pull
  • 17. + 17 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
