decreased, increased

As the salinity of seawater increases, its:

density increases

Sea surface salinity is greatest at which of the following latitudes?

25 degrees

the average salinity of typical seawater is

3.5%

which of the following best defines temperature?

The direct measure of the average kinetic energy of a substance's molecules.

which of the following best defines heat?

The energy transfer from one body to another due to a difference in temperature.

of all the following processes which one increases the salinity of water

evaporation

A layer of rapidly changing salinity with depth is called a ________.

halocline

many if the unique properties of water are attributed to the fact that water

is a polar molecule

the surface tension of water

is relatively high

A beaker contains a mixture of ice and pure liquid water at 0oC. What happens to the temperature of the liquid water as heat is added?

it remains constant until the ice melts, an then it begins to rise

which of the following surface seawater salinity conditions would you predict for the following location: latitude:60 N longitude:20 W

low surface seawater salinity due to precipitation

An area of the ocean where rapid change in ocean density occurs with a change in depth is the:

pycnocline

which of the following best defines latent heat?

the energy that hold needed to break the intermolecular bonds that hold molecules in place

hydrogen bonds form between neighboring water molecules because of

the polarity of water molecules

which of the following best defines melting point?

the temperature at which a solid changes to a liquid

A rapid change in ocean temperature with a change in depth occurs in the:

thermocline
