Ch.16 The Oceans, Coastal Processes, and Landforms
World wide average salinity is
3.5%
Brackish water would be most likely to occur
In a deltaic swamp
The moon's gravitational pull on the Earth is greater than that of the Sun's
True
An earthquake, submarine landslide, or eruption of undersea volcano is capable of producing a
Tsunami
Which of the following is not an example of a depositional coastal land-form?
Wave cut platform
A terrace is
an uplift wave-cut platform
smallest ocean in the world in terms of area is
arctic
The concentration of dissolved solids in the seawater is called
salinity
which of the following is incorrectly matched?
spring tides-high tides only
Waves in shallow water that "feel bottom" are
taller and more closely spaced
Which of the following is not true of tides?
the are produced solely by the gravitational pull of the sun.
Which of the following is not an example of an erosional coastline land-form?
tombolo
A general term for the coastal environment is
Littoral zone
Which of the following occurs when the sun, moon,and Earth are in alignment?
Maximum tidal ranges occur
which of the following is true of the ocean deep zone?
water does not freeze because of the intense pressure, and because of its salinity. A&B
From inland to the ocean, which sequence of zones is correct?
Coast, backshore, foreshore, nearshore
Although many elements are dissolved in seawater; no gases are dissolved in it
False
As the evaporation rate increase, salinity decreases
False
Brine water tends to occur near coastal deltas
False
Seawater is not a solution
False
Brine water results from
high evaporation rates
The height of a tsunami grows as it approaches a coastline primarily because
its wavelength shortens
About 2% of the oceanic mass comprise the
mixing zone of blended solutes and temperatures
Near the shore, waves of transition begin to "feel bottom" and, as a result, the orbits of the water molecules in the wave become
more elliptical and the process eventually cause breakers to form.
The largest ocean in the world in terms of are is
pacific
