Which does not have an effect on water's density?
a. Temperature
b. Pressure
c. Viscosity
d. Salinity
ANS: C
Density can be affected by temperature, salinity, and pressure. For example, water's density increases
as temperature decreases. This is a normal occurrence, but water takes on a unique behavior. At
approximately 4? Celsius, water's density begins to decrease again. Slight changes in the density of
water can lead to layering of water masses in the ocean. Information can be found in the section Water
