Study Guide 2 Oceanography

Hydrogen bonds form beytween neighboring water molecules because of

The polarity of the water molecule

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 state of matter in which water exists is primarily determined by

temperature

Laytent heat is the quantity of heat gained or lost as a substance undergoes a

change in state

Which of the following best describes hyydrogen bonding

Electrostatic attraction between charged areas of adjacent molecules

Which property of water causes ciastal communitiess to have only moderate differences in daily highs and lows when compared to inland communities

High heat capacity

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

It remains constant until the ice melts, and then it begins to rise.

In comparison to most other liquids, the heat capacity of liquid water is

higher than other liquids

The average salinity of typical seawater is

3.5%

Which process increases the salinity of water?

Evaporation

The transfer of water between the atmosphere, the oceans, and the continents is known as the

Hydrological cycles

As the salinity of seawater increases, its

density increases

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

thermocline

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

poycnoline

Which of the following best defines melting point?

The temperature at which a solid changes to a liquid

Which of the following occurs at the same temperature as the boiling point?

Condensation Point

Which of the following best defines heat?

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

Which of the following best defines latent heat?

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

Which of the following best defines temperature?

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

A layer of rapidly changing salinity with depth is called a

halocline

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

25 degrees

The density curve for high latitudes shows... density at the surface and…. density at depth

decreased; increased

The salinity curve for low latitudes shows... salinity at the surface and… salinity at depth

increased; decreased

Which surface seawater salinity conditions would you predict for Latitude

60°N, Longitude: 20°W? Low surface seawater salinity due to precipitation
