Review for Semester Final Exam
Day 3Items 35 - 51
35What can be said of a valley glacier
that lengthens (advances, or extends its terminus downslope)
over a period of many years?accumulation exceeds wastage
36List three indirect effects of ice
age glaciers.extinction of some organismschanges in some river courses
sea level fluctuations
37Describe a “hanging valley” that
results from previous glacial movement.
A feature on the side of a glacial trough that is likely to host a
waterfall or steep rapids.
38List three factors that could have had a
significant effect upon climatic variations and advances and retreats of ice sheets
during the Pleistocene epoch.variations in the Sun's energy output
precession of Earth's orbitwobbling of Earth's rotational axis
39Define the term “outwash plain.”
a broad accumulation of stratified drift deposited adjacent to the
downstream edge of an end moraine
40What is the most abundant salt
in seawater?sodium chloride (NaCl)
41In what regions of the oceans
is salinity the highest?in areas where evaporation is high and precipitation is low
42What two factors
determine the density of seawater?
temperature and salinity
43Why do most marine animals live near
the surface of the ocean?Most marine animals live near the
surface of the ocean because of sunlight, which supports
photosynthesis by marine algae that form the basis of the food chain.
44Name and describe the three major
categories of ocean-dwelling organisms.
plankton float with ocean currentsnekton are free swimmers
benthos are bottom dwellers
45What do we call the area where the land and ocean
meet and overlap?the intertidal zone
46What is the productivity in
temperate oceans determined by?
the seasons
47Make a general statement about the efficiency of the transfer of
energy between trophic levels in a food web or chain.
The transfer of energy between trophic levels is very inefficient, and can be as low as 2%-10%.
48Make a general statement concerning the likelihood of survival of animals that feed through a food chain rather than through
a food web.Food webs are more complex and provide
a variety of food sources for larger animals, each source with its own
separate food chain.
49Define the term “primary
productivity” as it applies to biological trophic levels.
Primary productivity is the amount of carbon fixed by organisms through the
synthesis of organic matter using energy derived from solar radiation or
chemical reactions.
50What type of shoreline feature
would indicate that the land had been uplifted or that sea
level had fallen?an elevated marine terrace
51Name two landform
features that are created by wave erosion.
sea arches and sea stacks
