Intro To Oceanography Final Exam Questions with
Correct Answers
Resultant tidal forces are produced by:
the difference between centripetal and gravitational forces.
the force produced by Earth's rotation matched with the spin of the
Moon.
density forces balanced by the force of buoyancy.
the Coriolis effect (not a true force) combined with Ekman transport.
none of the above. Correct Answer-the difference between centripetal
and gravitational forces
The reason that a lunar day is _________ a solar day is
because__________________.
longer than; the Sun rises later every morning
longer than; the Moon is also moving in its orbit around Earth
shorter than; the Sun rises earlier every morning
shorter than; the Moon experiences retrograde motion
the same as; the Moon and the Sun remain in fixed positions relative to
Earth Correct Answer-longer than, the Moon also moving in its orbit
around Earth
A high tide is at 3:00 p.m. on a particular day. On the very next day, a
high tide would most likely be expected at Correct Answer-3:50 P.M.
,Of the following phases of the Moon, which one is associated with the
smallest tidal range?
quarter-moon
gibbous moon
new moon
crescent moon
full moon Correct Answer-quarter-moon
During the time of a solar eclipse, which of the following statements is
NOT true?
The Moon would be in new moon phase.
Neap tide conditions are experienced.
From the Earth, the Sun is at least partially blocked out by the Moon.
The Earth-Moon-Sun system is in alignment (a straight line).
The Moon is in syzygy.
None of the above (all of the above statements are true). Correct
Answer-Neap tide conditions are experienced.
Destructive interference between the solar and lunar tidal bulges occurs
during:
,every day at about noon.
spring tide.
every night at about midnight.
apogee.
perigee.
neap tide. Correct Answer-neap tide
Syzygy occurs during:
every night at about midnight.
apogee.
perigee.
spring tides.
neap tides.
every day at about noon. Correct Answer-spring tides
True or False? The gravitational force between two bodies is dependent
on mass and distance, with distance being the factor that influences
gravitational force the most. Correct Answer-True
True or False? In a simple model of the tides as tidal bulges, the
strongest gravitational influence = maximum seawater bulge = highest
tide. Correct Answer-True
, True or False? The best time to go collecting at a tide pool (when there
would be the lowest low tides) is during neap tide conditions. Correct
Answer-False
The greatest tidal range on Earth occurs during the times when the Moon
is at ___________ and the Sun is at ___________.
perigee; perihelion
perigee; aphelion
apogee; perihelion
apogee; aphelion
None of the above; it depends on other factors. Correct Answer-perigee;
perihelion
A tidal pattern with two nearly equal high tides and two nearly equal low
tides per lunar day is called a __________ tidal pattern.
diurnal
quasidiurnal
pseudodiurnal
semidiurnal
mixed Correct Answer-Semi - Diurnal
A tidal pattern with one high tide and one low tide per lunar day is called
a __________ tidal pattern.
