Oceanography: EXAM 2 Questions with CorrectAnswers
Angle of of Earth's Tilt on its Axis Correct Answer-~23.5 degrees
Ecliptic Correct Answer-the plane traced by Earth's solar orbit
Earth's Seasons: explanation Correct Answer-1) caused by unequal
distribution of solar energy across Earth's surface due to the planet's tilt
and rotation on its axis
the 4 "Marks" of Earth's Seasons Correct Answer-1) vernal equinox
2) summer solstice
3) autumnal equinox
4) winter solstice
Vernal equinox Correct Answer-1) starts on March 21
2) equal amounts of light and dark
Summer solstice Correct Answer-1) starts on June 21
2) the sun is directly over the Tropic of Cancer (23.5 degrees N latitude)
Autumnal equinox Correct Answer-1) start of decrease in daylight and
increase in moonlight
2) sun is directly over the equator
,3) September 23rd
Winter solsitce Correct Answer-1) December 21st
2) sun is directly over the Tropic of Capricorn (23.5 degrees S latitude)
Declination Correct Answer-1) the angular distance of the Sun from the
equatorial plane
2) varies between 23.5 N/S latitudes
Arctic Circle: latitude Correct Answer-66.5 N
Antarctic Circle: latitude Correct Answer-66.5 S
Solar Energy: at low latitudes Correct Answer-1) high angle of
incidence (higher concentration)
2) highest between the Tropic of Cancer and Tropic of Capricorn
Solar Energy: at high latitudes Correct Answer-1) low angle of
incidence (low concentration)
Oceanic Heat Flow: high latitudes Correct Answer-1) more heat lost
than gained
2) heat loss due to high albedo effect from ice
3) low solar ray incidence
,Oceanic Heat Flow: low latitudes Correct Answer-1) more heat gained
than lost
2) high solar ray incidence
Albedo Correct Answer-the amount of light/heat being reflected
Atmosphere: chemical compostition Correct Answer-1) N2 (70%)
2) O2 (21%)
3) other gases (including GHGs)
Convection cells: definition Correct Answer-the cycles of rising and
sinking air due to density/temperature differences
Convection cell behavior: warm air Correct Answer-1) rises
2) less dense
Convection Cell Behavior: cool air Correct Answer-1) sinks
2) more dense
Convection Cell Behavior: moist air Correct Answer-1) rises
2) less dense
Convection Cell Behavior: dry air Correct Answer-1) sinks
, 2) more dense
Atmospheric Pressure: thick column of air at SL Correct Answer-1) high
surface pressure = 14. 7 lbs/in^2 = 1 atm
2) varies on daily basis
3) cool, dense air sinks
Atmospheric Pressure: thin column of air at SL Correct Answer-1) lower
surface pressure
2) warmer, moist air rises
Movement of Air Correct Answer-from high pressure to low pressure
"Wind" Correct Answer-moving air
The Coriolis Effect: general Correct Answer-1) deflects path of a
moving object from viewer's perspective (Right in N. Hemisphere/ Left
in S. Hemisphere)
2) caused by Earth's rotation around axis
3) does not exist at equator
4) increases as latitude increases
5) has the greatest effect on objects that move long distances across
latitudes
Coriolis Effect: north hemisphere Correct Answer-deflect to the right
