  1. LITHOSPHERE ROCK CYCLE PLATE TECTONICS VOLCANOES & EARTHQUAKES

  2. ROCK CYCLE

  3. Forces & Materials in the Rock Cycle • Forces • WEATHERING and EROSION • HEAT and PRESSURE • COMPACTION and CEMENTATION • MELTING and COOLING • Materials • IGNEOUS ROCK • SEDIMENTARY ROCK • METAMORPHIC ROCK • MAGMA • SEDIMENTS

  4. PLATE TECTONICS http://www.youtube.com/watch?v=ryrXAGY1dmE

  5. Causes of Plate Tectonics • Mantle Convection • Transfer of thermal energy by the movement of heated matter in the mantle • Rising mantle – divergent boundary • Falling mantle- convergent boundary • Push and Pull • Ridge push • Slab pull

  6. Types of Boundaries • CONVERGENT • Where 2 tectonic plates are moving together • Creates a subduction zone • Trenches, island arcs and folded mountains • DIVERGENT • Where 2 tectonic plates are moving apart • Volcanism, earthquakes and high heat flow • TRANSFORM • Where 2 tectonic plates are sliding horizontally past one another • Long faults and shallow earthquakes

  7. Convergent = Destroy oceanic-continental continental-continental oceanic-oceanic • Form either a subduction zone or a continental collision • Earthquakes and volcanoes are common • Oceanic-Continental • Cascade Mountain Range • Continental-Continental • Himalayas • Oceanic-Oceanic • Mariana Trench, Japan, Aleutian Islands

  8. Ring of Fire

  9. Divergent = Create • Black Hills, SD • East African Rift Valley • Red Sea • Mid-Atlantic Ridge

  10. Transform = Conserve • Two Types • Dextral – right side to observer • San Andreas Fault • Sinistral – left side to observer

  11. Volcanoes http://video.nationalgeographic.com/video/environment/environment-natural-disasters/volcanoes/west-mata-submarine-volcano-vin/ http://video.nationalgeographic.com/video/environment/environment-natural-disasters/volcanoes/volcano-eruptions/
