Ocean Basins
Vast bodies of salt water that separate the continents are called
Oceans
the measure of the ocean's saltiness is called
salinity
There are this many life zones in the ocean
Five
the marine organism lifestyle of living on the bottom (being a bottom dweller)
Benthic
There is only one ocean
True - 1 Ocean divided into 5 Ocean basins
Pacific
the 2 most important chemicals in seawater are
Sodium and Chlorine
This zone is between low tide and the continental shelf.
Littoral Zone
a continuous, gentle shower of fine organic matter, falling from the photic zone into the aphotic zone is called
marine snow
Seawater is 3.5% sodium chloride and 96.5% water
False - seawater is 96.5% water and 3.5% other materials includes sodium chloride
Arctic
where fresh water meets seawater it lowers the salinity and is called
Brackish
photic zone, aphotic zone, and abyssal zone are all apart of this
Open ocean
the marine organism lifestyle that are active swimmers and do not live on the bottom
pelagic
The oceans are the source for most of the Earth's atmospheric oxygen
True
Old-Earth Scientists
the layer of seawater affected by atmospheric temperature is called
between the low and high tide sits the
Intertidal zone
2 earth cycles that are major factors to the circles of all life on earth
Carbon and Nitrogen cycles
the oceans surface make the earth into a smooth sphere
False - The earth itself is not a sphere, and mean sea level varies with location
who believes that earth began as a water planet, and that God probably created a single super continent
Young-Earth Geologists
the density of seawater is the main factor that determines how fast _______ travels through it.
Sound
the absence of light is a characteristic of what 2 zones
aphotic, and abyssal
the long term AVERAGE of local high and low tides is called
Mean Sea level
the freezing point of seawater decreases as salinity increases
True - the higher the salinity the lower the temperature in order to freeze
