  3. Row 1, Col 1 An unconformity What does the “x” represent?

  4. 1,2 Silurian A layer of shale is located below Devonian limestone and above Cambrian sandstone. Overturning has not occurred. During which period was the shale most likely deposited?

  5. 1,3 443-490 mya How many million years ago did the surface bedrock under Watertown, NY form?

  6. 1,4 Half-life What is the term used to describe the amount of time it takes for half of a radioactive substance to become stable?

  7. 2,1 Contact metamorphic rock What feature is represented by the symbol surrounding the igneous intrusion?

  8. 2,2 11,400 years A sample of wood that originally contained 100 grams of carbon-14 now contains only 25 grams of carbon-14. Approximately how many years ago was this sample part of a living tree?

  9. 2,3 C The diagram below is a portion of a geologic time line. Letters A through D represent the time intervals between the labeled events, as estimated by some scientists. Fossil evidence indicates that the earliest birds developed during which time interval?

  10. 2,4 11,400 years old A sample of wood found in an ancient tomb contains 25% of its original carbon-14. The age of this wood sample is approximately…

  11. 3,1 Quartzite What type of metamorphic rock would be found where layer E and layer H come in contact?

  12. 3,2 Dinosaurs Scientists believe that a large asteroid struck the Earth approximately 65 million years ago. It is often theorized that this event led to the extinction of what major species?

  13. 3,3 4200 my How old are the oldest known rocks on Earth?

  14. 3,4 12.5% The half-life of carbon-14 is 5,700 years. After 17,100 years how much carbon-14 would remain?

  15. 4,1 The fault because it cuts through the igneous intrusion. Which is younger, the fault or the igneous intrusion? Why?

  16. 4,2 Volcanic eruptions It is inferred that during the early Archean Era the atmosphere of Earth contained water vapor, carbon dioxide, nitrogen and other gases in small amounts. How did these gases get here?

  17. 4,3 1 Which pie graph best shows the relative length of time of the major intervals of Earth’s geologic history?

  18. 4,4 2.6 x 109 What is the approximate age of an igneous rock that contains only one-fourth of its original Potassium-40 content due to radioactive decay?

  19. 5,1 Conglomerate Which rock layer is the oldest?

  20. 5,2 2. Shale containing trilobite fossils • Of the 4 choices listed below, which rock is most • likely the oldest? • Conglomerate containing the tusk of a mastodont • Shale containing trilobite fossils • Sandstone containing fossils of flowering plants • Siltstone containing dinosaur footprints.

  21. 5,3 Placoderm Fish Which NYS fossil species was around for the shortest period of time?

  22. 5,4 39,900 years The table below gives information about the radioactive decay of carbon-14. Part of the table has been deliberately left blank for student use. After how many years will 1/128 gram of the original carbon-14 remain?
