L2 plate boundaries ap

  1. 1. What happens at different plate boundaries?
  2. 2. 1) Destructive plate boundary Oceanic and continental, which goes beneath the other? Continental and continental? What happens? LO: What happens at different plate boundaries?
  3. 3. 1) Destructive plate boundary When an Oceanic and Continental plate meet, the heavier oceanic plates subducts (sinks) beneath the lighter continental plate. This is called a Subduction Boundary. LO: What happens at different plate boundaries?
  4. 4. 1 4 3 2 5 1.a. Subduction plate boundary LO: What happens at different plate boundaries?
  5. 5. 1) Destructive Plate Boundary a) Subduction boundary The oceanic plate _______ under the continental plate because it is denser. As the plate descends it starts to melt due to the _______ caused by the movement between the plates. a. Flops, heat c. descends, friction b. hides, friction d. descends, noise This melted plate is now hot and forms liquid ____ (magma). The magma rises through the gaps in the continental plate. If it reaches the ________, the liquid rock forms a volcano. a. earth, bottom C. ice, Arctic b. rock, bottom D. Rock, Surface LO: What happens at different plate boundaries?
  6. 6. 1.b. Collision Boundary • What happens when a continental and continental plate collide? LO: What happens at different plate boundaries?
  7. 7. b. Collision Boundary • When ______ continental plates meet each other they collide, rather than one ________ beneath the other. This causes them to buckle upwards. The ________ are an example a collision boundary. A. Three, sinking, Thames C. Two, sinking, Himalayas B. Two, sinking, north downs D. Five, melting, Himalayas
  8. 8. 2. Constructive Plate boundary LO: What happens at different plate boundaries?
  9. 9. Constructive plate boundary LO: What happens at different plate boundaries?
  10. 10. Mid-Atlantic ridge LO: What happens at different plate boundaries?
  11. 11. LO: What happens at different plate boundaries?
  12. 12. LO: What happens at different plate boundaries?
  13. 13. 2) Constructive Plate Boundary • At a _________ plate boundary, two plates move apart. As the two plates move apart, magma _____ up to fill the gap. This causes ________ at this type of boundary. a. Constructive, rises, volcanoes c. destructive, splashes, volcanoes b. Constructive, builds, flooding d. constructive, pushes, rain. • However, since the magma can ______ easily at the surface the volcano does not erupt with much force. _________ are also found at constructive boundaries. An example of a constructive boundary is the Mid-Atlantic ________. a. erupt, humans, volcano c. escape, earthquakes, ridge b. escape, floods, mound d. move, volcanoes, Iceland LO: What happens at different plate boundaries?

  15. 15. Animation
  16. 16. 3. Conservative plate boundary • Conservative plate boundaries exist where two plates do not directly collide but ____ past each other along a fault (weakness). • No _______ are found along these plate boundaries, but earthquakes do occur. An example of such a boundary is the San Andreas Fault in ________ . a. slide, volcanoes, California c. Move, earthquakes, Cowes b. Move, volcanoes, Canterbury d. Slide, volcanoes, Cardiff LO: What happens at different plate boundaries?
