Chapter 5 Properties of Water
PolaritySeparation of an electric charge in a molecule.
CohesionThe attraction of water molecules to other water molecules.
AdhesionThe attraction of water molecules to other polar molecules.
EndothermicWarm- blooded organisms.
ThermoclineA narrow zone that separates warm surface water from cool bottom water.
Archimedes PrincipleThe buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.
SalinityThe total amount of solid material dissolved in water.
HalocineA zone of rapid change in salinity.
StenohalineOrganisms that cannot tolerate changes in salinity.
EuryhalineOrganisms that can adapt to some fluctuation in salinity.
AcidsHigher concentrations of hydrogen ions that pure water.
BasesLower concentration of hydrogen ions that pure water.
Photic ZoneLight is present (10% of the ocean).
Aphotic ZoneNo light is present (90% of the ocean).
TurbidityA measure of suspended solids.
Secchi diskA device used to measure turbidity.
Compensation ZoneThe depth were the rate of photosynthesis is equal to the rate of respiration.
