Atom
Basic unit building block of matter
Nucleus
Made up of protons and neutrons
Portons
Positive particles
Neutrons
Neutral particles
Isotopes
Atoms with same number of protons but different number of neutrons
Heat
Energy of moving moecules
Temperature
Average measure of molecules kinetic energy
Density of water
Increases as temperature decreases to a maximum of 4 degrees Celsius
Why does ice Float?
Because it has less density of water

Total amount of solid material dissolved in water excluding dissolved organic matter
Name three processes that desalinate sea water
Distillation
Electrolysis
Reverse Osmosis
Explain the global pattern of surface ocean salinity variation
Polar regions-salinity is lowered
Low latitudes- salinity highered
Equator-salinity lowered, RAIN
Evaporation
Increases seawater salinity
(T/F) Sodium and Chloride are the most abundant ions in seawater?
True
(T/F) The density of seawater is affected by salinity and temperature?
True
(T/F) pH will tend to rise in areas of the ocean with high primary productivity
True
The Surface tension of water.....
Increases as density increases (a)
The amount of energy that is necessary to raise the temperature of one gram of water by one degree C
is called the:
