Oceanography Chapter 5 test
negatively charged subatomic particles that orbit an atomic nucleus
electrons
All of the following processes decrease the salinity of water except:
evaporation
The density of seawater is affected by salinity and temperature.
True
The average salinity of typical seawater is:
3.5%.
basic building blocks of all matter
atoms
Latent heat is the quantity of heat gained or lost as a substance undergoes a:
change in state.
bonds that hold adjacent water molecules together
hydrogen bonds
desalination solar distillation pycnocline electrolysis reverse osmosis
pynocline
A rapid change in ocean temperature with a change in depth occurs in the:
thermocline
temperature salinity thermocline pycnocline distillation
distillation
which latitudes would most highest average water temperature
low latitudes
Which latitudes with one find the highest average salinity for the surface ocean?
middle latitudes
All of the following are methods used to desalinate water except:
osmosis
pH latitude precipitation salinity temperature
pH
A. boiling point B. precipitation C. freezing point D. heat capacity E. surface tension
precipitation
As a whole,, the pH of the ocean is slightly alkaline
True
Any solution with a pH of greater than 7.0 is acidic.
False
In distillation, saltwater is highly pressurized to drive water molecules through a membrane to remove salts.
False
The density of seawater is slightly lower than the density pure water.
False
Deep-ocean water contains more carbon dioxide than surface water because deep water is colder and has the ability to dissolve more gases.
True
Precipitation, runoff, melting icebergs, and sea ice formation all decrease salinity.
True
Water is the only naturally occurring substance on Earth that readily exists in all three states of matter simultaneously (ice, water, and water vapor).
True
bonds that involve the sharing of electrons between atoms
covalent bonds
precipitation
decreases seawater salinity
river input
decreases seawater salinity
Which property of water causes coastal communities to have only moderate differences in daily highs and lows when compared to inland communities?
high heat capacity
which latitudes would be most likely to have no pycnocline
high latitudes
sodium ion calcium ion potassium ion hydrogen ion magnesium ion
hydrogen ion
evaporation
increases seawater salinity
sea ice formation
increases seawater salinity
charged atoms due to the gain or loss of one or more electrons
ions
many of the unique properties of water are attributed to the fact that water:
is a polar molecule
The surface tension of water:
is relatively high
The states of matter in which water exists is primarily determined by:
temperature
The Principle of Constant Proportions states that:
the relative concentrations of the major ions in seawater does not change.
