2
True or false Erosion occurs when rocks are not
moving
3
False
4
What can be moved because of erosion?
5
Rocks, sediment, and Earth materials
6
The formation of sand dunes is the result of
A abrasion
B chemical weathering
C erosion by moving water
D deposition
7
Deposition
8
The rich topsoil of the prairie in the picture
shown makes this ecosystem suitable for the
growth of a variety of grasses. All of the
following processes contribute to the formation
of the topsoil in the prairie except A
weathering of rocks B ocean waves C deposition of
weathered material D decomposition of living
things
9
ocean waves
10
_______is the most important erosional agent and
erodes most often in streams or rivers.
11
Water is the most important erosional agent and
erodes most often in streams or rivers.
12
A hurricane forms over the ocean and hits the
Texas coast and travels inland. What is the most
likely effect of this event? A More species of
animal will inhabit the coast B The shape and
size of beaches will be changed C The affected
area will be less vulnerable to future natural
disasters
D Native plants will never inhabit the area
again
13
B The shape and size of beaches will be changed
14
When the scooter hits a rock, the rider tends to
fly forward because A objects at rest tend to
stay at rest B the scooter is subjected to a
balanced force C a force opposes the motion of
the scooter but not the rider D unbalanced forces
cause objects to move at a constant speed
15
C. a force opposes the motion of the scooter but
not the rider
16
Which of the following is a force that can
oppose or change motion? A. gravity B. air
resistance C. friction
D. all of the above
17
D. all of the above
18
(No Transcript)
19
A. reducing the force required to lift the load.
20
The picture shows a simple fixed pulley being
used to lift a heavy box. Which of these does
the pulley change?
A    A. The mass of the box being moved
B    B. The amount of force required to move the box
C    C. The direction of force required to move the box
D    D. The amount of energy required to move the box
21
C. The direction of force required to move the box
22
Chemical weathering happens quickly in ______,
_______environments because water is needed for
the chemical reactions.
23
warm, moist
24
In chemical weathering, a rock is broken down by
______ ______that change its mineral
composition and physical and chemical properties
25
chemical reactions
26
True of False Water can chemically weather rocks
by dissolving rocks.
27
True
28
True of False Living organisms such as Lichens
do not chemically weather rocks.
29
False
30
True of False Rust is a form of chemical
weathering
31
True
32
Mechanical weathering __________ breaks rocks
down into smaller pieces
33
physically
34
True or False Weathering happens to rocks that
are moving.
35
False
36
Explain how this is an example of weathering?
37
The tree roots are growing into the rock prying
it into smaller pieces
38
How does freezing and thawing cause mechanical
weathering?
39
When water freezes, it expands causing the cracks
go grow
40
What is abrasion?
41
Abrasion is mechanical weathering in which rocks
rub against each other wearing them down
42
What is it called when a glacier picks up a rock,
or sediments off of the ground?
43
Plucking
44
How can wind be a cause of erosion?
45
Wind can blow sediment (dirt) from one place to
another
46
What happens to rocks and sediment that are
plucked by glaciers whenever the glacier melts?
47
The rocks and sediment are deposited in a new
location.
48
Describe how waves in the ocean can cause erosion.
49
Waves can cause beaches and coastlines to be
reformed time after time
50
What force causes rock slides and mud flows?
51
Gravity!
