1
Which activity demonstrates chemical weathering?
grinding of talc into a powder
dissolving of limestone by acid rain of statues or creating caves below
freezing of water in the cracks of a sandstone sidewalk
abrasion of a streambed by tumbling rocks
2
As a quartz pebble is transported by a stream, the pebble will become more rounded as a result of
abrasion by colliding with other rocks
deposition in well-sorted layers
dissolving as water is running over the rock
resistance to weathering and erosion
3
As these sediments empty into the ocean, which area will have boulders and largest sediments drop out of the water first
Area C
Area B
Area A
Area D
4
Which statement best describes the physical weathering shown by the diagram?
Enlargement of the cracks occurs because water expands when it freezes.
The cracks become wider because of chemical reactions between water and the
This type of weathering occurs only in bedrock composed of granite.
Type of weathering is common in regions of primarily warm and humid climate
5
Which type of weathering will occur when average yearly temperature is 5°C and the average yearly precipitation is 45cm?
moderate chemical weathering
slight frost action
moderate chemical weathering with frost action
very slight weathering
6
Which erosional agent most likely piled the silt against these buildings?
Water
chemical weathering
wind
mass movement/gravity
7
Which process most likely produced the present appearance of this feature?
plate tectonics
wind erosion
earthquake vibrations
volcanic eruption
8
This soil was formed primarily by
permeability and human activity
weathering and biological activity
erosion by running water
erosion by wind
9
Why did these caverns and sinkholes form?
This type of bedrock contained large amounts of oxygen and silicon.
The bedrock chemically reacted with acidic groundwater.
Crustal uplift formed gaps in the bedrock.
Glacial deposits altered the shape of the bedrock.
10
Which cross section best represents the appearance of this cobble after many years of exposure to the wind-driven sand?
D
A
C
B
11
Four quartz samples of equal size and shape in a stream. Which of the samples below were transported the farthest?
3
4
2
1
12
The water depth is greater near bank
A
than bank
B
because the water velocity near bank
A
is
faster, causing erosion to occur
faster, causing deposition to occur
slower, causing deposition to occur
slower, causing erosion to occur
13
One type of weathering is mechanical the other is?
physical
blizzard
chemical
stormy
14
Landscapes will undergo the most chemical weathering if the climate is
cool and dry
warm and dry
warm and wet
cool and wet
15
Which two locations have the greatest stream velocities?
A and B
D and A
C and D
B and C
16
Which force ensures that water always flows downhill?
magical unicorns
wind
emotions
gravity
17
The canyon in the picture below was formed by which type of weathering
Ice
Water
High temperatures
Wind
18
Which particle will deposit the fastest when a stream enters a lake?
clay
boulders
sand
pebbles
19
Which type of sediment would you expect to find in glacial deposits?
unsorted and jagged/irregular!
sorted and triangular!
unsorted and round!
sorted and color coordinated
20
What is erosion?
Deposits of rock
Sediment settles out while it is being eroded
Water, wind or ice carry away broken down rock
A process in which wind, water or temperature break down rocks
21
This sand dune was most likely formed by
water flowing from the right
wind blowing from the right
water flowing from the left
wind blowing from the left
22
This geologic feature called a DELTA shown in the photograph was primarily deposited by which agent of erosion
gravity
running water
wind
weathering
23
Compared to the stream velocity between point
X
and point
Y
, the stream velocity between point
Y
and point
Z
is
greater, since the slope of the land decreases
greater, since the slope of the land increases
less, since the slope of the land increases
less, since the slope of the land decreases
24
What is weathering?
something that changes the water cycle
What causes rocks to form
The movement of rock to a new place
The breaking down of rocks into smaller pieces
25
This must occur
before
erosion can take place
Weathering
Deposition
Anti-erosion
Ice melting
26

28
When the velocity of a stream suddenly
decreases
, the sediment being transported undergoes an increase in
deposition
mass movement
particle density
erosion
29
What is erosion?
What causes rocks to form
something that changes the water cycle
The breaking down of rocks into smaller pieces
The movement of rock to a new place
30
Sediment is deposited as a river enters a lake because the
volume of water increases
slope of the river increases
force of gravity decreases
velocity of the river decreases
31

32
Why should you wear green on St. Patrick's Day?
It's the color of a shamrock.
You will get one million dollars.
You will be invisible to leprechauns.
It's the best color in the whole wide world.
