2. Objective Students will be able to describe 4 features of sedimentary rocks.

3. Word of the Day Feature: A distinctive quality or characteristic. Settle: To cause to sink.

4. Sedimentary Features Bedding: Horizontal layering. Results from sediments settling out of water or wind.  2 Kinds  Graded Bedding: Bedding in which small particles are on top and large particles are on bottom (a progression.)  Cross Bedding: Bedding in which layers of sediment are slanted.

5. Sedimentary Features Bedding in Sedimentary Rocks.

6. Sedimentary Features Graded- Bedding in Sedimentary Rocks.

7. Sedimentary Features Cross- Bedding in Sedimentary Rocks.

8. Sedimentary Features Ripple Marks: When sediment is moved into small ridges by wind or water.  Symmetrical Ripples: Produced by Oceans.  Asymmetrical Ripples: Produced by Rivers.

9. Sedimentary Features Sorting and Rounding: Sediments are initially jagged in shape, but become round as they are transported.  Hard minerals (quartz) have a better chance of becoming rounded. Evidence of Past Life: Sedimentary rocks may contain Fossils.
