2. Classifying Rocks 3 rock types Sedimentary Igneous Metamorphic

3. Sediment Rock fragments, minerals, or plant and animal remains that settle out of water or air

4. Sedimentary Rocks “that which has settled” Formed from sediments Sediments=rocks exposed to weather that have been broken down into very small pieces Formation depends on weathering/erosion Sediments packed into layers Cement together over time

5. Sedimentary

6. Sediments change into Rock by  Pressure  Cemented together by new minerals to form rock

7. Coal Sedimentary rock formed from remains of plants, bark roots, and other plant material that is buried and under pressure Contains NO minerals

8. Conglomerate Sedimentary rock with pieces of shells, rocks, minerals or other products that are larger than 2 mm cemented together with minerals.

9. Limestone Sedimentary rock made of shells and skeletons of ocean organisms. Over time the individual shells are no longer visible and become limestone

10. Sedimentary Rock and Wind Water movement: Larger sediment drops before smaller sediment Wind Direction : Cross- beds, Ripples, Mud Cracks
