The Atmosphere and Its Effects
1. A pressure of 1036.0 mb when converted to inches would
2. A pressure reading of 29.50 inches when converted to millibars
would equal ________.
3. When converted to millibars, an air pressure of 29.90 inches of
Mercury would equal ________.
4. Students wish to study the effect of elevation above sea level
on air temperature and air pressure. They plan to hike in the
Adirondack Mountains from Heart Lake, elevation 2,179 feet, to the
peak of Mount Marcy, elevation 5,344 feet. Which instruments
should they use to collect their data?
(1) anemometer and barometer
(2) thermometer and anemometer
(3) thermometer and barometer
5. A dedicated Earth Science student using an aneroid barometer uses the
air pressure at the base of Slide Mountain as 1016.0 mb. At the same time another
dedicated student measures the pressure at the top of the mountain. Which
pressure reading could be correct at the top of Slide Mountain?

(1) 1004.0 mb and 29.90 inches
(2) 992.0 mb and 29.29 inches
(3) 1016.0 mb and 30.10 inches

*Planetary winds (ESRT page 14) influence ocean currents (ESRT page 4)
*Ocean currents are formed when wind blows over the surface of water, transferring its energy
*Northern Hemisphere- ocean currents spin clockwise; Southern Hemisphere- counterclockwise
1. When the eye of a hurricane is at the 43o N latitude, it most likely is being pushed by planetary winds
2. Surface ocean currents located at 40o south latitude, 90o west longitude generally flow toward the
_______________. (northeast, southeast, west, or southwest)
3. What surface ocean current is located at 30o N, 75o W?
4. Surface ocean currents resulting from the prevailing winds over the oceans illustrate the transfer of energy
(1) Lithosphere to atmosphere
(2) Hydrosphere to lithosphere
(3) Atmosphere to hydrosphere
(4) Stratosphere to troposphere
5. The California Ocean Current, which flows along the west Coast of North America, is a
(1) Cool current, flowing north
(2) Cool current, flowing south
(3) Warm current, flowing north
(4) Warm current, flowing south
