3. Foliated rocks = bands or lines of minerals

4. Non-foliated rocks= no distinct lines shown

5. Sedimentary rocks

6. Sedimentary rocks Sedimentary rocks are formed from sediments Sediments are formed from weathering and erosion : examples = soil and sand

7. compaction Compaction= the forces of pressure on the bottom layers of sediment.

8. cementation cementation = when water and mineral act like glue between the sediments Special minerals are calalite , hemalite and limonite.
