NEW YORK STATE REGENTS EXAMS
PHYSICAL SETTING / EARTH SCIENCE - JANUARY 2002

11 Energy is transferred from the Sun to Earth mainly by

(1) molecular collisions
(2) density currents
(3) electromagnetic waves
(4) red shifts

12 Which surface ocean current transports warm water to higher latitudes?

(1) Labrador Current      (3) Gulf Stream
(2) Falkland Current       (4) West Wind Drift

13 Which factor has the greatest influence on the weathering rate of Earth’s
surface bedrock?

(1) local air pressure
(2) angle of insolation
(3) age of the bedrock
(4) regional climate

14 Compared to dull and rough rock surfaces, shiny and smooth rock surfaces
are most likely to cause sunlight to be

(1) reflected         (3) scattered
(2) refracted         (4) absorbed

Base your answers to questions 15 through 17 on the block diagram below, which
shows some of the landscape features formed as the most recent continental glacier
melted and retreated across western New York State.

15 During which geologic epoch did this glacier retreat from New York State?

(1) Pleistocene
(2) Eocene
(3) Late Pennsylvanian
(4) Early Mississippian

16 The moraines pictured in the block diagram were deposited directly by the glacier.
The sediments within these moraines are most likely

(1) sorted by size and layered
(2) sorted by size and unlayered
(3) unsorted by size and layered
(4) unsorted by size and unlayered

17 The shape of elongated hills labeled drumlins is most useful in determining the

(1) age of the glacier
(2) direction of glacial movement
(3) thickness of the glacial ice
(4) rate of glacial movement
