Reviewing Main Ideas
1
Weathering and Soil Formation

• Weathering includes processes that break down
  rock.

• During mechanical weathering, physical processes
  break rock into smaller pieces.

• During chemical weathering, the chemical
  composition of rocks is changed.

• Soil evolves over time from weathered rock.
  Parent rock, topography, climate, and organisms
  affect soil formation.

Erosion of Earth's Surface

• Erosion is the wearing away and removal of rock
  or sediment.

• Agents of erosion include gravity, ice, wind, and
  water. Downslope movement of a portion of the
  land's surface is called mass movement.

Erosion of Earth's Surface

• All agents of erosion move rock and sediment.
  When energy of motion decreases, sediment is
  deposited.

• Erosion and deposition determine the shape of the
  land.

Question 1
Where would you be more likely to find soil high
in organic matter? Why?
A. desert B. grassland C. polar D. tropical
PS 2.1h
39
Chapter Review
Answer
Tropical areas are more likely to have soil high
in organic matter because the humid climate
creates warm, moist weather patterns. As plants
and animals die and decay, humus forms. Humus is
rich in organic matter and helps soil hold water
and provides nutrients that help plants grow.

Question 3
Which is an example of a chemical change?
A. a rock eroded by acid B. boiling water C.
evaporation D. melting ice
PS 2.2h
42
Chapter Review
Answer
The answer is A. A chemical change occurs when
the chemical composition of the original product
changes. When carbonic acid comes into contact
with certain rocks, the rocks dissolve and a new
product is left in its place.

Question 4
A large sandstone boulder is weathered to form
several smaller sandstone boulders. What is this
an example of?
A. acid dissolution B. a change in state C. a
chemical change D. a physical change
PS 2.1h
44
Chapter Review
Answer
The answer is D. The weathered rocks have the
same chemical composition of the original rock,
they have just been broken into smaller pieces
over time.

Question 5
What five factors affect soil formation?
Answer
Type of parent rock being weathered, topography
of an area, climate, time, and organisms in the
soil all affect soil formation.

Question 1
What occurs when heavy moisture
saturates sediments and causes them to flow
downhill over the grounds surface?
PS 2.1h
47
Standardized Test Practice
A. creep B. mudflow C. rock slide D. slump
PS 2.1h
48
Standardized Test Practice
Answer
The answer is B. Mudflows are a mixture of water
and sediment that flow downhill over the grounds
surface.

Question 2
Which is an accumulation of silt deposited by
wind?
A. loess B. outwash C. rill D. till
PS 2.1i
50
Standardized Test Practice
Answer
The answer is A. Wind can blow fine sediment or
silt. When this sediment is deposited, an
accumulation called loess can blanket Earths
surface.

Answer
The answer is A. Plant roots produce tannin
which can form tannic acid. This acid can
dissolve minerals in rock.

Question 4
What results when wind leaves behind particles
that are too heavy to move?
A. abrasion B. deflation C. glacial deposition D.
sheet flow
PS 2.1i
55
Standardized Test Practice
Answer
The answer is B. When wind blows over the land
it lifts and carries small particles like silt
and sand. Often, heavy rocks that are too heavy
to be lifted by wind are left behind. This is
called deflation.

PS 2.1i
57

Answer
The answer is C thin sheets of water flow
downhill and carry loose sediment with it.
