What is the main marine adaptation that allows organisms to survive freezing water temperatures?
Some have a type of antifreeze in their blood, which lowers the freezing point of their internal fluids
decrease the salt content with their tissues to prevent freezing
Growing a fur coat
Swimming to a tropical waters
Zonation in tidal zones is the result of all the following except:
alternation between submersion and exposure to air
competition and perdation
grazing-affects algal distribution
run and hide method
High stress for sessile organisms due to exposure of the elements is cause by all of the following except:
Desiccation - drying out
Predation
Temperature and Salinity changes
Floods
Barnacles and Mussels are found in the
Middle Intertidal or Littoral zone
Lower Intertidal or Infralittoral zone

The term turbulence refers to
wave action
calm seas
self-destruct
hurricane winds
Desiccation is the process of
drying out
floating on the surface of water
taking in water
changing color

attached and stays in place
to die off
moves with tide
is motile
What is the main causes of Zonation?

Coastal Plain
Coastal plains are deeper than Bar-built bays or lagoons
True
False
The estuary with the highest walls are usually
Fjords
Coastal Plain
Tectonic
Bar-built
The deepest estuaries are
Tectonic
Coastal Plains
Fjords
Bar-built
Freshwater species have the ability to survive in waters with less than a 10% concentration of salt in the water.
True
False
The salt concentration in an estuary decreases as you head towards the river.
True
False
The greatest challenge of estuary organisms is maintaining a water and salt balance in cells and bodily fluids.
True
False
The ‘Z’ shaped leading edge where freshwater and saltwater meets is called
Salt wedge
Halocline
Euryhaline
Stenohaline
Which of the following is not related to a Bar-built estuary?
are also called lagoons
are also called bays
are found on the Texas Coast
are only found in Canada
An area partially enclosed body of water where freshwater mixes with saltwater is called a(n)
Estuary
Bay
Marsh
Valley
The salinity concentration of ocean water is .35%.
True
False
A salty gradient where two water masses meet is called a halocline.
True
False
Tectonic estuary were developed by
Faulting of land surfaces along major faults.
Rising sea-levels filling existing river valleys.
Glacial movement
Ocean water pushing sand into piles,
Brackish water are areas where freshwater combines with ocean waters.
True
False
Salt water will float on top of freshwater due to saltwater's greater density.
True
False
Organisms can only endure a narrow range of salinity are called
Stenohaline Marine Species
Euryhaline Marine Species
Freshwater Species
Brackish Water Species
This is caused when a sandbar traps fresh water and mixes it with ocean water.
