Properties of Sea water
The unique properties of water are a result of what two elements
Hydrogen and Oxygen
14.7 pounds per square inch
The three ways water transmits heat
conduction, convection and radiation
the sticking of salt on a sediment particles surface
adsorption
Where 02 production balances the CO2, above this depth more O2 is produced and above more CO2 is produced
compensation depth
What are shared electrons between hydrogen and oxygen
Covalent Bonds
33 ft (10m) per 1 atmosphere
The way conduction works in water
heat is passed from water molecule to water molecule
which gases are critical to life on earth and creates a chemical balance in the ocean
nitrogen, carbon dioxide and oxygen
a decrease in ocean pH due to elevated global emissions
ocean acidification
because the electrons are shared unequally, water has a slightly negative end and slightly positive end
strong dipole
Pressure at deepest ocean trench (36,000 ft)
16,170 pounds per square inch
how convection works in water
heat is transferred as water is cooled and sinks or warms and rises
nitrogen
the process of obtaining freshwater from saltwater
desalination
this is why water is the universal solvent
Because of the polarity water can form weak bonds called hydrogen bonds
The compressibility of water
Almost incompressible
the strength of water as a conductor
poor
the location in the ocean that has a well lit surface and is where the most photosynthetic oxygen is produced
euphotic or photic zone
60% of this comes from the ocean
magnesium
What are the three states of water
Solid, liquid, gas
Pressure effects from scuba diving
equalization of air spaces
how radiation works in water
water is heated from above through solar radiation
lack or 0% oxygen at the bottom of deep stagnant water
anoxic condition
70% of this comes from the ocean and is used for medicine, flame retardant, gas additive, pesticides
bromine
