Some questions may require the use of the Earth Science Reference Tables. Base your answers to questions 60 through 62 on the notes below written by a student during field trips to three different locations in New York State. NOTES Location A Location B Location C Good view from this hilltop; chilly and windy. We rested to catch our breath, then collected samples. Rocks are visible everywhere. There are boulders, cobbles, and pebbles of many sizes and shapes mixed together. These surface rock fragments are composed of metamorphic rock sitting on the limestone bedrock. The teacher showed us parallel scratches in the bedrock. I saw almost no soil. It is rocky and the streambank is steep. Where we are standing, we can see a waterfall and rapids. It is cool by the water. From the streambed we collected pebbles and cobbles some red, some white, others a mixture of many colors. The streambed is full of rocks of all sizes. The teacher warned us to be careful of the strong stream current. It is cool in the shade, and the rock cliff above us still has some ice on it from winter. The rocks we are sitting on have sharp edges. Rock fragments at the bottom of the cliff are the same color as the cliff. Our teacher warned us to watch out for falling rocks. 60 a State the agent of erosion that deposited most of the sediment found at location A. [1] b State one observation recorded by the student that supports this conclusion. [1] 61 Some samples of sediment collected from the streambed at location B are shown below. Explain why these samples are smooth and have rounded shapes. [1] 62 Explain how ice in cracks on the cliff at location C may have helped cause weathering of the bedrock on the face of the cliff.

[1] 65 State how incoming solar radiation (insolation) is affected by the ozone in the atmosphere. [1] P.S. E./Sci. Aug. 01 [19] [OVER] Base your answers to questions 66 through 70 on the weather satellite photograph of a portion of the United States and Mexico provided in your answer booklet. The photograph shows the clouds of a major hurricane approaching the eastern coastline of Texas and Mexico. The calm center of the hurricane, the eye, is labeled. 66 This hurricane has a pattern of surface winds typical of all low-pressure systems in the Northern Hemisphere. On the satellite photograph provided, draw three arrows on the clouds to show the direction of the surface wind movement outside the eye of the hurricane. [1] 67 Cloud droplets form around small particles in the atmosphere. Describe how the hurricane clouds formed from water vapor. Include the terms dewpoint and either condensation or condense in your answer. [1] 68 State the latitude and longitude of the hurricane s eye. The compass directions must be included in the answer. [1] 69 At the location shown in the photograph, the hurricane had maximum winds recorded at 110 miles per hour. Within a 24-hour period, the hurricane moved 150 miles inland and had maximum winds of only 65 miles per hour. State why the wind velocity of a hurricane usually decreases when the hurricane moves over a land surface. [1] 70 a State two dangerous conditions, other than hurricane winds, that could cause human fatalities as the hurricane strikes the coast. [2] b Describe one emergency preparation humans could take to avoid a problem caused by one of these dangerous conditions. [1] P.S. E./Sci.

Part B 1 Score Part A Score 2 [1] [OVER] PHYSICAL SETTING/EARTH SCIENCE continued Directions to the Teacher Follow the procedures below for scoring student answer papers for the Physical Setting/Earth Science examination. Additional information about scoring is provided in the publication Information Booklet for Administering and Scoring Regents Examinations in Living Environment and Physical Setting/Earth Science. Use only red ink or red pencil in rating Regents papers. Do not correct the student s work by making insertions or changes of any kind. On the detachable answer sheet for Part A and Part B 1, indicate by means of a checkmark each incorrect or omitted answer. In the box provided at the end of each part, record the number of questions the student answered correctly for that part. At least two science teachers must participate in the scoring of each student s responses to the Part B 2 and Part C open-ended questions. 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 all 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. In the student s answer booklet, record the number of credits earned for each answer in the box printed to the right of the answer lines or spaces for that question. Fractional credit is not allowed. Only whole-number credit may be given to a response. If the student gives more than one answer to a question, only the first answer should be rated. Units need not be given when the wording of the questions allows such omissions. Raters should enter the scores earned for Part A, Part B 1, Part B 2, and Part C on the appropriate lines in the box printed on the answer booklet and then should add these four scores and enter the total in the box labeled Total Written Test Score. The student s score for the Earth Science Performance Test should be entered in the space provided. Then, the student s raw scores on the performance test and written test should be converted to a scaled score by using the conversion chart printed at the end of this Scoring Key and Rating Guide. The student s scaled score should be entered in the labeled box on the student s answer booklet. The scaled score is the student s final examination score. All student answer papers that receive a scaled score of 60 through 64 must be scored a second time. For the second scoring, a different committee of teachers may score the student s paper or the original committee may score the paper, except that no teacher may score the same open-ended questions that he/she scored in the first rating of the paper. The school principal is responsible for assuring that the student s final examination score is based on a fair, accurate, and reliable scoring of the student s answer paper. Because scaled scores corresponding to raw scores in the conversion chart may change from one examination to another, it is crucial that for each administration, the conversion chart provided in the scoring key for that administration be used to determine the student s final score. The chart in this scoring key is usable only for this administration of the examination. [3] [OVER] PHYSICAL SETTING/EARTH SCIENCE continued Part B 2 Allow a total of 13 credits for this part. The student must answer all questions in this part. 53 [2] a Allow 1 credit for June. 1 b Allow 1 credit for 23 2 N or Tropic of Cancer. 54 [1] Allow 1 credit for a correct response.

Allow only 1 credit if both required isotherms are plotted correctly but do not touch the borders of the map. or Allow only 1 credit if only one required isotherm is drawn correctly. or Allow only 1 credit if more than the two required isotherms are drawn and the two required isotherms are drawn correctly but the additional isotherms are incorrect. 57 [1] Allow 1 credit for a correct response. Acceptable responses include, but are not limited to, these examples: Dark surfaces are better absorbers of radiant energy. The parking lot reflects less sunlight than the surrounding area. The parking lot has a darker and rougher surface. [5] [OVER] PHYSICAL SETTING/EARTH SCIENCE continued 58 [3] a Allow no credit for writing the equation. b Allow 1 credit for correctly substituting both acceptable measurements into the equation given in part a.

To determine the student s final examination score, locate the student s total performance test score across the top of the chart and the student s total written test core down the side of the chart. The point where those two scores intersect is the student s final examination score. For example, a student receiving a total performance test score of 14 and a total written test score of 68 would receive a final examination score of 82.
