NEW YORK STATE REGENTS EXAMS
PHYSICAL SETTING / EARTH SCIENCE - JANUARY 2003

Part B1 - Answer all questions in this part.

Directions (3650): For each statement or question, write on your separate answer sheet the number of the word or expression that, of those given, best completes the statement or answers the question. Some questions may require the use of the Earth Science Reference Tables.

36 The table below shows the duration of insolation at different latitudes for three different days during the year.

Which dates are represented most correctly by Day 1, Day 2, and Day 3, respectively?

(1) March 21, September 22, December 21
(2) June 21, September 22, December 21
(3) September 22, December 21, March 21
(4) December 21, March 21, June 21

Base your answers to questions 37 and 38 on the graph below, which
shows changes in the Suns magnetic activity and changes in the number of  sunspots over a period of approximately 100 years. Sunspots are dark, cooler areas within the Suns photosphere that can be seen from Earth.

37 The graph indicates that years having the greatest number of sunspots occur

(1) randomly and unpredictably
(2) precisely at the beginning of each decade
(3) in a cyclic pattern, repeating approximately every 6 years
(4) in a cyclic pattern, repeating approximately every 11 years

38 Which graph best represents the relationship between the number of sunspots and the amount of magnetic activity in the Sun?

39 A student performed a laboratory activity in which water was poured slowly into four cups containing equal volumes of loosely packed sediment samples, as shown in the diagram below. All particles were spherical in shape and uniform in size within a container. After the water level reached the surface of each sample, the student determined the amount of water  that had been added.

The results of the activity should have indicated that approximately equal amounts of water were added to the cups of

(1) silt and pebbles, only
(2) sand, silt, and pebbles, only
(3) pebbles and the mixture, only
(4) sand, pebbles, and the mixture, only

40 The diagram below shows the apparent path of the Sun as viewed by an observer at a certain Earth location on March 21.

At which latitude is the observer located?

(1) the Equator (0)        (3) 66 1/2 N
(2) 23 1/2 N                (4)90 N
