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
