The layer in which density increases

• densocline
• halocline
• thermocline
• pycnocline

Salinity is measured in 

• parts per million
• parts per thousand
• milligrams
• milliliters

Which of the following would not cause salinity to increase?

• Melting

• Increased volcanic activity

• Evaporation

• Freezing

The largest constituent in sea water is

• Potassium

• Magnesium

• Sodium

• Chlorine

How do salinity and temperature affect the density of ocean water?

• salinity increase = density increase, temp decrease = density increase
• salinity decrease = density increase, temp. decrease = density decrease
• salinity increase = density increase, temp increase = density increase
• salinity decrease = density increase, temp increase = density increase 

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances
