I also have some books that you may want to use.
( 5 points for each correct answer ).
the peculiar temperature relationship of water. At what temperature ( in oC ) is water density the
greatest? What would the marine
environment at the poles be like if water had its density increase as the
temperature approaches 0 o C? Discuss.
expect CO 2 to be limiting to plants for their photosynthesis in the
sea ? Why ?
continental shelf extends offshore for up to 400 km off eastern Canada, but
extends only a few km offshore along most of the Pacific coast of North America.
Explain this relationship in terms of plate tectonics.
the term ectothermic ( poikilothermic ) mean? When the water temperature changes, what are the consequences
to the physiology of the organism?
ectothermic animals like fish live in seawater, which is actually about 0 o
C, how come they don’t freeze? Discuss
keeps the various water masses ( upper, middle, and deep ) from mixing?
don’t waves have much effect in disrupting a thermocline?
To what do the terms wavelength, frequency, and period refer in
relationship to waves?
the Coriolis effect. Why is it not
considered to be a real force? Discuss.
What is a
keystone species? What is a
keystone predator? How are humans a
mechanism do planktonic organisms use to stay afloat?
What is a
copepod? What is the genus name of
most abundant copepod in the sea? How
are copepods important to humans?
water freeze in the same way a distilled water? Discuss.
deep ocean currents driven by temperature and salinity differences?
waves increase in height and finally break when they enter shallow water?
travels faster in water than in air. How
does this fact influence marine and terrestrial predators that use sound to
the three larval types which Vance describes? What are the advantages of each?
a protozoan be considered a “ r – selected “ species?
a whale be considered a “ K – selected “ species?
19. Why are there no terrestrial animals with the ability to detect electrical activity in other animals as is the case in marine animals? Discuss
