  1. Ch. 4–4 Sedimentary Rocks Review Earth Science

  2. 1. Sedimentary rocks form • Pieces of other things • From fire • From heat and pressure • From cooling magma Response Grid

  3. 2. What are the three types of sedimentary rocks? • Intrusive, Extrusive, Volcanic • Igneous, Sedimentary, Metamorphic. • Coarse, Medium, Fine • Detrital, Organic, Chemical. Response Grid

  4. Random Question:What Percentage of American Teens went online last year • 53% • 82% • 90% • 98.3%

  5. 3. This rock is formed from • Organic - shells • Detrital– Medium • Solutions • Detrital– coarse Response Grid

  6. 4. What are all the types of weathering? • Smashing • Only chemical • Only physical • Chemical and physical Response Grid

  7. Fastest Responders (in seconds)

  8. 5. When minerals act like glue to hold sediments together this is called . • Cementation. • Fermentation. • Mineralization. • Filtration. Response Grid

  9. Fastest Responders (in seconds)

  10. 6. This rock is formed from • Detrital- Fine • Organic - shells • Solutions • Organic - plants Response Grid

  11. 7. What does detrital mean? • They are made from solutions • They are made from volcanoes • They are made from living things • They are made from pieces of other rock Response Grid

  12. 8. Why does the United States have large areas of limestone? • Fields used to cover the U.S. • Water used to cover the U.S. • Desert used to cover the U.S. • Forests used to cover the U.S. Response Grid

  13. 9. This rock is formed by • Detrital- Fine • Detrital– Coarse • Solutions • Organic – dead plants Response Grid

  14. Random Question: How much skin will you shed over your life time? • 3 pounds • 8 pounds • 25 pounds • 40 pounds

  15. 10. Erosion is the process that? • Breaks down rock • Sticks sediments together • Puts pressure on sediment • Moves sediment Response Grid

  16. 11. Why is organic sedimentary rock often rich in the mineral calcite? • Plants often accumulate on the ocean floor • Ships often dump calcite on ocean floors • Animals with shells often accumulate on ocean floors • Ocean floors contain calcite Response Grid

  17. Fastest Responders (in seconds)

  18. 12. This rock is formed by • Organic - Plants • Detrital- Coarse • Detrital– Fine • Solutions Response Grid

  19. 13. Why can’t humans just make more fossil fuels like coal? • We aren’t sure how coal is made • Coal is formed over millions of years of compacting plant materials within Earth • We’re not sure what coal is made from • Coal is formed from synthetic materials that humans don’t have access to Response Grid

  20. Random Question:What are the odds you will live to be 116? • 1 in 2 Billion • 1 in 1 million • 1 in 4 trillion • 1 in 100,000

  21. 14. Sedimentary rocks are formed when sediments are pressed and cemented together. • True • False Response Grid

  22. 15. This rock is formed from (Hint: Will not fizz in acid) • Solutions • Detrital- medium-grained • Detrital—Fine-grained • Organic - shells Response Grid

  23. Fastest Responders (in seconds)

  24. 16. Compaction is the process that occurs when water soaks through soil and rock • True • False Response Grid

  25. 18. This rock is formed from • Detrital– coarse grained • Detrital– fine grained • Organic - plants • Solutions Response Grid

  26. 17. The process that occurs when pressure from upper layers of sediment push on lower layers is called compaction. • True • False Response Grid
