1
Which of the followiing landscapes were not carved by glaciers?
 
the Grand Canyon
2
A glacier forms when
 
snow accumulates to form ice and the ice mass begins to flow under its own weight.
3
The water table is found at the
 
top of the zone of saturation
4
Caves and caverns are formed in carbonate rock by
 
reaction of carbonic acid released into the groundwater
5
The flow of a glacier begins
 
after it has reached a critical mass.
6
Water able to be contained in the subsurface depends on
 
porosity
7
The flow of ground is dependent on
 
hydraulic conductivity and pressure
8
Which has the longest residence time
 
polar ice caps and glaciers
9
The most important agent of erosion is
 
water
10
The depositionaal landform at the farthest advance of a glacier is called a
 
terminal moraine
11
As a large reservoir behind a new dam fills with water, what happens to the water table in...
 
the water table rises
12
V-shaped valleys are
 
 common in mountainous regions
13
Through which of the following is the infiltration of water greatest?
 
sandy soil
14
When a perched water table intersects the surface on a hillside, the result is
 
a spring
15
In a delta environment the first grains to settle are
 
coarse-grained sediment
16
The discharge of a stream is directly related to the
 
cross-sectional area of a channel and the average stream velocity
17
Evaporation and precipitation are greatest over the
 
oceans
18
Movement of water erodes stream channels. The main source of erosion comes from
 
physical abrasion of water and rock particles
19
As water flows around a river meander, erosion occurs
 
on the outside of the meander
20
In a delta environment we find that fine-grained sediments settle
 
far away from the mouth of the stream channel
21
Water precipitation over land completes its cycle as it
 
all of these
22
Of the three agents of erosion-water, wind, and ice- the one with the ability to move only...
 
wind
23
Evaportation and pprecipitatioin are in balance over the
 
oceans
24
Glaciers lose mass by
 
melting and calving
25
In a meandering stream, dposition of sediment occurs on
 
the inner side of a meander
26
Glacial debris is generally
 
a mishmash of shapes and sizes
27
Stalactites from
 
from water rich in calciium dripping from a cave ceiling and from a cave ceiling downward
28
Which of the following is a necessary condition for an ice mass to be a glacier
 
the ice mass must move under its own weight
29
The principal cause of erosion and transportation of sediment in a desert environment is
 
water
30
The most powerful agent of erosion is
 
glacial action
31
Common galcial landforms created of drift include moraines
 
and drumlins
32
What determines the maximum sediment load of a stream
 
stream discharge
33
The necessary condition to produce an artesian system is
 
a confined aquifer under sufficient pressure
34
Deltas form
 
as streams enter a standing body of water
35
In a well in an unconfined aquifer,what is the highest level water can rise to if there is...
 
to the level of the water table
36
Stream velocity is dependant on
 
gradient, channel geometry,and discharge
37
Point bars typically form
 
on the inside of a curved stream channel
38
The flow of groundwater depends on
 
hydraulic gradient and hydraulic conductivity
39
Stream velocity is faster in a
 
stream with a very steep gradient
40
On a floodplain, stream flow is generally
 
meandering
41
Glaciers will retreat when the amount of accumulation
 
is less than the amount of ablation each year
42
The formations of rock hanging from the roofs of caves are called
 
stalactites
43
As sediment travels in a downstream river, it changes by getting
 
finer
44
Where does most rainfall on Earth finally end up before becoming rain again?
 
in the oceans
45
The transport of large particle sizes is greatest
 
when steam speed is very fast
46
Stalactites form
 
from water rich in calcium dripping from a cave ceiling and from a cave ceiling downward
47
Most of the Earth's fresh water is located in
 
polar ice caps and glaciers
48
The most common drainage network is the
 
dentritic drainage pattern
49
Headward erosion of a group of cirques around a mountain may produce
 
a horn
50
Which of the following is not involved in cave formation in limestone?
 
land subsidence
51
The capacity a material has for transmitting fluids is known as its
 
permeability
52
Landforms created by glacial erosion include
 
hanging valleys, cirques, and roches moutonnees.
53
A moraine is a
 
glacier deposit
54
Land subsidence is generally not reversible because
 
the compacted clay layers cannot be expanded
55
Water in the unsaturated zone is called
 
soil-moisture
56
When subsurface ground material is completely saturated with water, we call it
 
groundwater and the saturated zone
57
As water is withdrawn from a well, the water table around the well
 
drops, creating a cone of depression
58
Snow converts to glacial ice when subjected to
 
pressure
59
The greater the hydraulic gradient the
 
the faster the flow
60
The typical mountain valley that has been subjected to glaciation is shaped like
 
The letter "U"
61
Water is vital to life on our planet. Most of the Earth's water supply is in the
 
oceans
62
The maximum volume of sediment a stream can carry is dependent on the stream's
 
discharge
63
Streams transport great quantities of sediment. The most effective transport of sediment occurs...
 
turbulent flow
64
The poorest absorber of water is
 
rocky surfaces with no soil layer
65
A rock with very low porosity will most often have a
 
low permeability
66
The headwater flow of a mountain stream is generally characterized as
 
turbulent
67
On a floodplain, the sediment grains away from the main river channel are
 
fine-grained silts and clays
68
As streams move downslope, channel dimension generally
 
widens
69
Blocks of ice buried in a glacial moraine often result in the formation of
 
small glaciel lakes
70
The region above the zone of saturation is called
 
the zone of aeration
71
The driving force of our planet's hydrologic cycle comes from
 
solar energy
72
The necessary condition to produce an artesian system is
 
a confined aquifer under sufficient pressure
73
Precipitation exceeds evaporation over the
 
continents
74
The Mississippi River has a huge water and sediment capacity. As such, the river also has a...
 
course of the river lengthens and the delta grows
75
The annual amount of snow lost by a glacier is called
 
ablation
76
What is the lowest level to which water can erode land?
 
sea level
77
As water flows around a river meander, erosion occurs
 
on the outside of the meander
78
In a meandering river, erosion is most notable on
 
on the outer side of the meander 
79
In general, sinkholes are found in areas
 
dominated by limestone
80
Over withdrawal of groundwater causes ground subsidence in areas
 
underlain by  unconsolidated sediments
81
Within a stream channel, the speed of stream flow is greatest
 
in the middle of the channel at the water's surface
