When will tidal range be greatest? - CORRECT ANSWER-Spring tide in
January
Spring tides are present when the lunar and solar tide waves are in phase
with each other. - CORRECT ANSWER-True
Tides of large amplitude occurring every two weeks at the new and full
moon are called _______ tides. - CORRECT ANSWER-Spring
In a deep fjord with a shallow entrance sill, the deep basin water is
probably - CORRECT ANSWER-low in oxygen and high in nutrients.
The net seaward flow of water in a partially mixed estuary is nearly uniform
over depth. - CORRECT ANSWER-False
Pollutants that adhere to suspended particles in an estuary are usually
flushed from the estuary by the net circulation. - CORRECT ANSWER-
False
A partially-mixed estuary generally has a two-layered flow that moves
inward at depth and seaward at the surface. - CORRECT ANSWER-True
,In a well-mixed shallow estuary, the net seaward flow occurs at -
CORRECT ANSWER-All depths
Sea surface salinity is a function of _________ and __________. -
CORRECT ANSWER-precipitation; evaporation
Carbon dioxide concentrations in seawater increase with depth. -
CORRECT ANSWER-True
Surface salinities at high latitudes tend to be greater in summer than winter.
- CORRECT ANSWER-False
Instruments used to measure the electrical conductivity of seawater can
produce continuous readings of salinity with depth or continuous readings
of salinity with time at a fixed depth. - CORRECT ANSWER-True
Seawater percolating through the fractured crust along ridge systems acts
to both remove salts from and add salts to seawater. - CORRECT
ANSWER-True
Increasing salinity increases density. - CORRECT ANSWER-True
The properties of seawater at depth are determined by surface conditions
in the area where the water sinks. - CORRECT ANSWER-True
, In the oceans the zone where density of water changes rapidly with depth
is called a pycnocline. - CORRECT ANSWER-True
Many combinations of salinity and temperature of seawater can produce
the same density of seawater. - CORRECT ANSWER-True
A rapid change in temperature with depth is called a - CORRECT
ANSWER-Thermocline
Water of a lower density usually lies below water of a greater density. -
CORRECT ANSWER-False
Usually temperature, salinity, and pressure distributions cause ocean water
density to increase with depth. - CORRECT ANSWER-True
A water mass at depth in the ocean has temperatures and salinities which
are usually determined by the conditions that were present when the water
mass was last at the sea surface. - CORRECT ANSWER-True
Density of Mediterranean Intermediate Water is influenced more by salinity
than temperature. - CORRECT ANSWER-True
