Dinosaur Skull Offers Hints About Africa s Past A fossil skull was found in Africa among many dinosaur bones from the Late Cretaceous Epoch. This skull came from a dinosaur named Rugops primus, or first wrinkle face. This meat eater, believed to have been about 30 feet long and to have lived 95 million years ago, belonged to a group of dinosaurs called abelisaurids. This fossil skull, unearthed in the Sahara Desert in 2000, provides new evidence that Africa split from other southern continents at a later time than previously thought. Before this discovery, abelisaurids from that period had been found only in South America, Madagascar, and India, but not in Africa. This new fossil, Rugops primus, found only in Africa, indicates that Africa was still connected to the other southern landmasses, at least by a land bridge, 100 million years ago. 54 During which geologic era is Rugops primus inferred to have lived? [1] 55 What evidence suggests that Africa was still attached to South America 100 million years ago? [1] 56 State the type of rock in which Rugops primus was most likely preserved.

[1] 82 Determine the altitude of Polaris at Kingston, New York, to the nearest degree. [1] Base your answers to questions 83 through 85 on the passage below. Mount Manaro Erupts! Mount Manaro is a volcano on Ambae Island, about 1400 miles northeast of Australia. Ambae Island is located in the South Pacific Ocean at 15 south latitude, 168 east longitude. After Mount Manaro had erupted in 1995, Ambae Island residents developed an evacuation plan. When Mount Manaro began erupting gas, steam, and ash on November 27, 2005, scientists and residents watched the volcano carefully. The eruption became more severe on December 9, 2005, when steam and gases rose 1.8 miles up into the air. Rocks and ash began to fall on nearby farms and homes. Thousands of people left their homes, making it the largest evacuation ever on Ambae Island. 83 Name the highest layer of the atmosphere into which the steam from the volcanic eruption rose on December 9, 2005. [1] 84 Identify the ocean current off the northeast coast of Australia that most affects the climate of Ambae Island. [1] 85 On the diagram in your answer booklet, draw one arrow through point X and one arrow through point Y to indicate the direction of tectonic plate motion near Mount Manaro. [1] P.S./E. Sci.

Directions to the Teacher Follow the procedures below for scoring student answer papers for the Regents Examination in Physical Setting/Earth Science. Additional information about scoring is provided in the publication Information Booklet for Scoring Regents Examinations in the Sciences. Do not attempt to correct the student s work by making insertions or changes of any kind. Allow 1 credit for each correct response. At least two science teachers must participate in the scoring of the Part B 2 and Part C open-ended questions on a student s paper. Each of these teachers should be responsible for scoring a selected number of the open-ended questions on each answer paper. No one teacher is to score more than approximately one-half of the open-ended questions on a student s answer paper. Students responses must be scored strictly according to the Scoring Key and Rating Guide. For open-ended questions, credit may be allowed for responses other than those given in the rating guide if the response is a scientifically accurate answer to the question and demonstrates adequate knowledge as indicated by the examples in the rating guide. On the student s separate answer sheet, for each question, record the number of credits earned and the teacher s assigned rater/scorer letter. Fractional credit is not allowed. Only whole-number credit may be given for a response. Units need not be given when the wording of the questions allows such omissions. For hand scoring, raters should enter the scores earned in the appropriate boxes printed on the separate answer sheet. Next, the rater should add these scores and enter the total in the space provided. The student s score for the Earth Science Performance Test should be recorded in the space provided. Then the student s raw scores on the written test and the performance test should be converted to a scale score by using the conversion chart that will be posted on the Department s web site at: http://www.p12.nysed.gov/apda/ on Friday, June 15, 2012. The student s scale score should be entered in the box labeled Scale Score on the student s answer sheet. The scale score is the student s final examination score. Schools are not permitted to rescore any of the open-ended questions on this exam after each question has been rated once, regardless of the final exam score. Schools are required to ensure that the raw scores have been added correctly and that the resulting scale score has been determined accurately. Because scale scores corresponding to raw scores in the conversion chart may change from one administration to another, it is crucial that, for each administration, the conversion chart provided for that administration be used to determine the student s final score.
