This is a very basic presentation about the rock cycle for my 7th grade science class. The first eleven slides are narrated. After slide 10 there is a YouTube video with a rock cycle song. Slides 12-26 are an interactive review quiz. Enjoy!

Introduction To Rocks

  1. 1. Introduction to Rocks 7th grade science
  2. 2. What are rocks?  Rocks are a combination of minerals
  3. 3. Are all rocks the same?  No Igneous: Granite  Not only are they different colors, but there are also different types  The three main types are igneous, sedimentary, and metamorphic rocks. Metamorphic: Gneiss Sedimentary: Sandstone
  4. 4. Where do rocks come from?  Rocks are created, transformed, and destroyed in a process called the rock cycle  Interactive Rock Cycle Animation http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  5. 5. The rock cycle: Part 1  First of all there is no real beginning or end to the rock cycle.  However, for this lesson we will begin with igneous rocks.  Igneous rocks often forms when lava erupts from volcanoes then cools.
  6. 6. Igneous Rocks Can be:  Shiny  Crystalline  Porous http://geology.about.com/library/bl/images/blrockindex.htm
  7. 7. The rock cycle: Part 2  Secondly, the rock cycle is not a perfect circle, it does not occur in a specific sequence.  Igneous rocks can be re- melted, eroded, or pressed.  Rocks that are formed from eroded sediment are Sedimentary Rocks.
  8. 8. Sedimentary Rocks Can be:  Grainy, Sandy  Made of different pieces of rocks or minerals  Striped
  9. 9. The rock cycle: Part 3  Finally, rocks can be transformed over time to make new rocks.  Heat and pressure can create new rocks  These rocks are called Metamorphic rocks. http://www.tulane.edu/~sanelson/geol111/metamorphic.htm
  10. 10. Metamorphic Rocks Come in a variety of styles, shapes and colors Many have stripes, but not all Many contain unique crystal and mineral formations only unique to metamorphic rocks
  11. 11. Review  There are review questions about rocks on the following slides.  In order to progress through the quiz in the correct order you have to click the links on the slides.  Click the “Begin Quiz” link on this page to start the quiz. Begin Quiz
  12. 12. 1. True or False: The rock cycle always starts with igneous rocks and ends with metamorphic rocks. A. True B. False
  13. 13. 2. True or False: The rock cycle does not always follow the same order. A. True B. False
  14. 14. 3. Igneous rocks… A. Can be formed from pieces of sediment that have been compacted and glued together. B. Can be formed from molten magma or lava. C. Are formed when heat and pressure transform old rocks into new rocks.
  15. 15. 4. Sedimentary rocks… A. Can be formed from pieces of sediment that have been compacted and glued together. B. Can be formed from molten magma or lava. C. Are formed when heat and pressure transform old rocks into new rocks.
  16. 16. 5. Metamorphic Rocks A. Can be formed from pieces of sediment that have been compacted and glued together. B. Can be formed from molten magma or lava. C. Are formed when heat and pressure transform old rocks into new rocks.
