  1. Rock Cycle

  2. Rock Cycle • rock • A naturally occurring solid mixture of one or more minerals, rock particles or organic matter

  3. Rock Cycle • How are rocks classified? • Based on how they are formed • Some originate in magma • Others from sediments • Others are squished and heated.

  4. Rock Cycle • Three Types of Rocks • Igneous • Sedimentary • Metamorphic • Texture can help determine the type of rock

  5. Rock Cycle • Rock Cycle • The continual process by which new rock forms from old rock material.

  6. Rocks What are all the possible paths that the following rocks could take to form a new rock? Igneous Metamorphic Sedimentary

  7. Rock Cycle • Igneous Rocks • Sedimentary Rock • Form when molten rock cools • Rocks that weather and erode are called sediments • When sediments are compacted they create sedimentary rock

  8. Rock Cycle • Weathering • Sediments • Erosion • Compaction • Breaking down of rocks into tiny pieces • Tiny pieces of rock • Process of transporting sediments • Process of sediments becoming squished together to form a rock

  9. Rock Cycle • Metamorphic Rock • Forms when rocks are put under enormous heat & pressure

  10. Objective 11/29/11 Describe how each type of rock changes into another type as it moves through the rock cycle. Outro What is something about the rock cycle you still don’t understand or have a question about?
