Presentation Transcript

  1. When the plates collide (or convergent plate boundaries) LO: to be able to explain what happens when plate boundaries meet

  2. Key words we have learnt so far • Convergent • Divergent • Conservative • Oceanic • Constructive • Crust • Mantle • Ocean ridge • Plate • Core • Convection currents

  3. Diagram for memory • Get into pairs • Label yourself 1 and 2

  4. How did you do?

  5. Destructive plate margin (where a continental plate meets an oceanic plate)

  6. Labels: Neatly add these correct labels: Generally explosive volcanic eruptions. Magma rising to form volcanoes. Plate being forced into the mantle Deep, violent Earthquakes One plate is denser than the other so sinks. Plate melting. Subduction zone Oceanic plate Continental plate

  7. The Andes The Andes are found at a destructive margin along the western coast of South America The Andes (shown in white)

  8. Collision marginContinental and continental

  9. The Collision Zone • When continental plates collide head on with other continental plates, the result is upheaval! • Similar densities – neither plate is subducted • Gradual forward movement of each plate creates extreme pressures= earthquakes • Over time, the rock strata become folded, and rise to create mountain ranges

  10. The Alps and the Himalayas The Alps The Himalayas

  11. Oceanic/ oceanic boundary

  12. convergent Use page 102 in textbook to help!
