- 1. What happens at different plate boundaries?
- 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. 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?

- 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. 1.b. Collision Boundary • What happens when a continental and continental plate collide? LO: What happens at different plate boundaries?
- 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

- 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?

- 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?
