PART #1: see Fig. 1 Attached to this assignment you will find FIG. 1, which is a geologic time scale. Determine the correct intervals of geologic time. Indicate your answer by the name of the interval. Only provide the name of the intervalBe sure to spell correctly and begin each with a capital letter. DO NOT write the name & the interval. For example for question #19, only write Tertiary. Do not write Tertiary Period. For the boundaries asked for, provide the NUMBER DATES IN MILLIONS OF YEARS (Ma) TO THE FIRST DECIMAL PLACE. THE ANSWER IS 541.0 Ma FOR #8, FOR EXAMPLE. FOR FULL CREDIT, PART #1 ANSWERS SHOULD BE LABELED 1. TO 20. (EXAMPLE: 1. 2. 3. 4. 5. 6. ETC… 18. 19. 20.)

PART #2: see Fig. 2 On the right is a list of past life and other aspects of Earth’s geologic time. Match each of these with the correct geologic interval on the left. Only provide the capital letter of the match. For example, for #27 Miocene only write E. DO NOT write Ape-like primates diversified or E Ape-like primates diversified. FOR FULL CREDIT, PART #2 ANSWERS SHOULD BE LABELED 20. TO 30. ( EXAMPLE: 21. 22. ETC… 28. 29. 30.)

PART #3: see Fig. 3 The principles of stratigraphy are listed with the textbook chapters assigned for tonight’s lectures. These principles allow for the relative order of events in time to be worked out from geological layers. Using these principles, address these three questions: Question #31: What is the order in which the formations formed? Question #32: What principles did you chose to deduce this order? Question #33: Explain your answer for question #32. FOR FULL CREDIT, PART #3 ANSWERS SHOULD BE LABELED 31. 32. 33.

PART #4: see Fig. 4 The principles of stratigraphy are listed with the textbook chapters assigned for tonight’s lectures. These principles allow for the relative order of events in time to be worked out from geological layers. Using these principles, address these three questions: Question #34: What is the order in which the rock and sediment units formed? Question #35: What principles did you chose to deduce this order? Question #36: Explain your answer for question #35. FOR FULL CREDIT, PART #4 ANSWERS SHOULD BE LABELED 34. 35. 36.
