1. Quick-write Why do you think some rocks fizzed with acid?

2. Sedimentary Rocks Sedimentary rocks are formed when sediment is pressed and cemented together over millions of years.

3. Sediment is small pieces of material that have been broken off rocks and have been deposited by water, wind or ice.

5. Types of sedimentary rocks: 1)Limestone Made from sea shells. Sea shells are made from the mineral calcite. Smooth texture. Limestone rock fizzes when tested with acid.

6. Calcite is CaCO 3 (calcium carbonate). CaCO 3 + acid CO 2 CO 2 causes effervescence (fizzing)

8. 2) Sandstone Made from sand particles cemented together. Rough texture. When rubbed together sand particles break off. Does not fizz with acid; does not contain calcite.

10. 3 ) Shale Made from very small particles cemented together. Smooth texture. Black in color. May contain fossils. Does not fizz with acid; does not contain calcite.
