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
