2. A stream demonstrates regular, continuous flow only during the late spring and early summer of the year. Based on this information, a geologist would classify this stream as:
perennial
dendritic
intermittent
ephemeral
radial

3. A dendritic stream pattern will tend to develop in:
regions underlain by regularly-spaced joints or faults
regions of fold mountain belts
in flat-lying rocks of uniform composition
along the flanks of isolated volcanoes
in regions of vertically-oriented or tilted sedimentary rocks

4. Which one of the following (if any) does NOT represent an accumulation of alluvium?:
delta
alluvial fan
natural levee
point bar
ALL OF THESE FEATURES ARE ACCUMULATIONS OF ALLUVIUM

5. Point bars are deposited:
on the inside of stream meanders
on the outside of stream meanders
on the bottom-center of stream channels
at the base of watefalls
in abrasion potholes

6. As a river overflows its banks during flood, it drops much of its coarser-grained load immediately, forming landforms called:
deltas
alluvial fans
point bars
natural levees
backswamps

7. A base level is:
a device for measuring stream gradient
a device for measuring stream discharge
the lowest elevation to which a stream can cut its channel
a field marker that indicates a lake level
the highest elevation is a drainage basin

8. Which one of the following generally decreases downstream along the length of a stream?:
channel width
channel depth
gradient
water velocity
load

9. According to the Hjulstrom Diagram:
sand will be deposited from stream transport before gravel and clay
clay will be eroded from a stream bed before sand
gravel will be eroded from a stream bed before sand
sand will be deposited from stream transport before clay
clay will be deposited from stream transport before fine gravel

10. Stream saltation is:
the dissolution of salty minerals by flowing water
the grinding of abrasion potholes in a stream bed
a jumping process in bed load
a measure of the total dissolved solids in a stream
a measure of NaCl (only!) concentrations in a stream

11. Streams with very high amounts of bed load tend to:
downcut rapidly
become braided
confine themselves to a single, deep channel
process their load mainly by dissolution
characterize the river systems of eastern North Dakota

12. The ultimate base level of the drainage basin that includes the Red River of the North is:
Lake Winnipeg
the Nelson River
Hudson Bay
the low-head dam at downtown Fargo
the Gulf of Mexico

13. Mr. Stick looks down onto a broad valley but can't find the stream that carved it. Mr. Stick (correctly!) concludes that this represents a(n)________ stream valley:
impotent
overfit
wimpy
youthful
underfit

14. The development of which one of the following pairs of stream features is most dependent on the occurrence of mature natural levees along the trunk stream?:
yazoo tributaries and backswamps
waterfalls and rapids
oxbow lakes and meander scars
neck cutoffs and yazoo tributaries
point bars and backswamps

15. A region is characterized by the following: few lakes or swamps, well-developed floodplains, upland divides with even slopes and with rounded-to-knife-edged summits within easy view of the stream margin. William Morrison Davis would have gazed upon this region and classified it as:
adolescent
mature
youthful
a peneplain
old age

16. The Continental Divide sign along Interstate 94 between Valley City and Jamestown, N.D., marks the drainage divide between waters flowing:
to the Atlantic and Pacific Oceans
to Hudson Bay and the Gulf of Mexico
to Hudson Bay and the Pacific Ocean
to the Gulf of Mexico and the Saint Lawrence River
to Hudson Bay and the Saint Lawrence River

17. As a stream increases its channel length by developing a mature meander pattern, it also:
increases its velocity of water flow
increases its gradient
decreases its discharge
increases its competence
NONE OF THE ABOVE ARE TRUE!

18. Large, circular holes are visible in the bedrock floor of a stream known to undergo turbulent flow. These holes are:
karstic potholes
karstic sinkholes
abrasion potholes
plunge pools
abrasion sinkholes

20. A geologist views a stream terrace developed in alluvium. The evolution of this terrace could most probably have been associated with which one of the following events in the stream's history?:
increased discharge
an increase in the elevation of regional base level
increased load
decreased velocity
ANY OF THE ABOVE WOULD LEAD TO TERRACE DEVELOPMENT

21. For the drainage that includes the Missouri River, ultimate base level is at what elevation?:
0 feet
620 feet
715 feet
1012 feet
1366 feet

22. The Red River of the North at Fargo has poorly-developed point bars because:
the velocity of the river is too low for any deposition to occur
the velocity of the river is too high for any erosion to occur
the point bars are regularly swept away by floods
point bars cannot form on northward-flowing rivers
the dominant particle size in transport is clay

24. With respect to discharge, the two greatest rivers in North America are the Mississippi and the:
Missouri
Columbia
Saint Lawrence
Nelson
Mackenzie
