  1. 1. Igneous, Metamorphic, and Sedimentary Rocks<br />
  2. 2. Definition of Rock Type<br />Formation of Rock Type<br />Examples of each kind of rock<br />The Rock Cycle<br />Quiz<br />Summary<br />Overview<br />
  3. 3. What is an Igneous Rock?<br />Formed by the solidification of magma<br />Sail Rock/<br />Igneous Rock<br />Igneous Rock<br />
  4. 4. How are Igneous Rocks formed?<br />Process 1<br />Formed underground<br />Formed from melted rock(magma)<br />Magma trapped in small pockets<br />Magma cools down<br />
  5. 5. Process 2<br />Formed above ground<br />Volcanoes erupt<br />Magma flows above ground<br />As known as lava<br />Lava cools down<br />Igneous Formation Continued<br />
  6. 6. Granite<br />Scoria<br />Pumice<br />Obsidiar<br />Examples of Igneous Rocks<br />Granite Rock<br />Scoria Rocks<br />
  7. 7. What is a Metamorphic Rock?<br />Metamorphism- Change effected by heat/pressure<br />Produced by metamorphism<br />Creigh Hill, Scotland <br />
  8. 8. How are Metamorphic Rocks formed?<br />Once “igneous” or “sedimentary”<br />Rock under large amount of pressure<br />Heat builds up<br />This is what morphs(changes) them<br />

  10. 10. What is a Sedimentary Rock?<br />Formed by sedimentation of earth’s surface<br />Bryce Canyon National Park<br />Red Canyon, Utah<br />
  11. 11. How are Sedimentary Rocks formed?<br />Pieces of the earth breaks down<br />Wash downstream<br />Sit at bottom of the waters<br />Repeats process to form layers<br />Layers form pressure over time<br />Pressure forms the sedimentary rock<br />
