Definitions
Specific Heat
One caloire per gram of water per *C
Two elements that come from unique properties of water
Hydrogen and Oxygen
the content of dissolved salt is called what
salinity
what 3 gases are critical to life on earth
nitrofen, carbon dioxide, and oxygen
what are the nutrients needed for plant growth
nitrate, phosphate, silicate
Surface Tension
Elastic property of water surface
What are shared electrons between hydrogen and oxygen
The average of the worlds oceans contains what percent of dissolved salts
3.5%
what must happen to nitrogen in order for it to be utilized by living organisms
it must be fixed
what are the fertilizers of the ocean for plants
nitrates and phosphates
Density
mass per unit volume: grams per cubic centimeter
Why is water a universal solvant
because the polarity of the water can form weak bonds (hydrogen bonds)
what are the main things that affect sea surface salinity?
variations in precipitation and evaporation patterns
nitrogen, carbon dioxide, and oxygen compose what percent of gases in the atmosphere and the oceans
99%
what do silicates form
silica
Viscosity
liquid property that resists flow, Internal friction of a fluid
buoyancy
what is one thing that can dramatically lower ocean salinity
freshwater runoff from major rivers
what controlls oxygen in the ocean
photosynthetic production from plants
the nutrient concentration in the ocean is:
cyclical
Refraction
the bending of light and shound waves by density changes that affect the speed of light and sound
What does water allopw for in metabolism
chemical reactions and transportation of organic molecules
how many major ions make up 99% of seawater
6
what is anoxic conditions
no oxygen
what causes nutrient concentration to decrease
biological productivity
