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 Ocean trench Make sure you can explain how earthquakes and volcanoes occur at this plate boundary

  7. The Andes The Andes are found at a destructive margin along the western coast of South America. The liquid magma rises towards the surface to form volcanoes such as Aconcagua. The collision of the plates also causes uplift and the growth of the Andes. The Andes (shown in white)

  9. Mark scheme

  10. How did this person do?

  11. Collision marginContinental and continental

  12. 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

  13. The Alps and the Himalayas The Alps The Himalayas
