Ocean 101 Exam 2 Questions With Correct
Answers A+
Water of a lower density usually lies below water of a greater density. - Answer✔False
Usually temperature, salinity, and pressure distributions cause ocean water density to increase
with depth. - 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. -
Answer✔True
Density of Mediterranean Intermediate Water is influenced more by salinity than temperature. -
Answer✔True
Antarctic bottom water has a very narrow range of both salinity and temperature; this water is
nearly homogeneous. - Answer✔True
Temperature affects density in the Arctic Ocean more than salinity. - Answer✔False
The density of Arctic Ocean water is controlled more by salinity than by temperature. -
Answer✔True
The water type occupying the greatest volume of the Atlantic Ocean is - Answer✔North Atlantic
deep water
The time required to complete the tidal sequence of a solar tide is equal to the time period needed
to complete the sequence of a lunar tide. - Answer✔False
A rising tide is known as an ebb tide. - Answer✔False
When will tidal range be greatest? - Answer✔Spring tide in January
Spring tides are present when the lunar and solar tide waves are in phase with each other. -
Answer✔True
Tides of large amplitude occurring every two weeks at the new and full moon are called _______
tides. - Answer✔Spring

In a deep fjord with a shallow entrance sill, the deep basin water is probably - Answer✔low in
oxygen and high in nutrients.
The net seaward flow of water in a partially mixed estuary is nearly uniform over depth. -
Answer✔False
Pollutants that adhere to suspended particles in an estuary are usually flushed from the estuary by
the net circulation. - Answer✔False
A partially-mixed estuary generally has a two-layered flow that moves inward at depth and
seaward at the surface. - Answer✔True
In a well-mixed shallow estuary, the net seaward flow occurs at - Answer✔All depths
Sea surface salinity is a function of _________ and __________. - Answer✔precipitation;
evaporation
Carbon dioxide concentrations in seawater increase with depth. - Answer✔True
Surface salinities at high latitudes tend to be greater in summer than winter. - 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. -
Answer✔True
Seawater percolating through the fractured crust along ridge systems acts to both remove salts
from and add salts to seawater. - Answer✔True
Increasing salinity increases density. - Answer✔True
The properties of seawater at depth are determined by surface conditions in the area where the
water sinks. - Answer✔True
In the oceans the zone where density of water changes rapidly with depth is called a pycnocline.
- Answer✔True
Many combinations of salinity and temperature of seawater can produce the same density of
seawater. - Answer✔True
A rapid change in temperature with depth is called a - Answer✔Thermocline
In the Southern Hemisphere, the circulation of air about a low pressure system is clockwise. -
Answer✔True
The latitudes between approximately 30 degrees north and 30 degrees south have a heating
deficit over the course of a year. - Answer✔False
