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!
