Water Density Presentation
-Pure water=compound
-Individual Water molecules=covalent bonds
-Water molecules form between each other through hydrogen bonding
Water contains special properties because of polarity (hydrogen bonding)
Cohesion, Adhesion, surface tension allows life on earth.
Water has a density of 1gm/cm3
Solid state is less dense than its liquid state
Density=Measure of how much mass is contained in a given unit volume
Temperature, Salinity, Pressure
Cold, Salty water is more dense than warm, fresh water.
Dense water sinks below
Ocean waters can be divided in 3 layers (density)
Top layer is the least dense=Surface mixed zone
Pynocline=Transition zone-> Barrier between the surface zne and a bottom layer.
The deep zone is the most dense and is the bottom layer. Water here remains cold and dense.
Increasing temperatures will cause distinct layers to form in the water, reducing the mixing and in turn lower productivity.
Upwelling and downwelling (the upward and downward motion of sub-surface water toward the surface and bottom of the ocean.
Productivity=The amount of carbon available to the system as a result of photosynthesis.
Estuaries=Where fresh water meets salty ocean water.
