Karen has a birdbath made of poured concrete which can have many tiny
holes. When she bought it, the salesman suggested that she seal the surface
with a watertight paint. Why was this suggestion made?
A
In cold, wet weather, any water that seeped into the concrete could
freeze and cause the birdbath to crack.
B
The watertight paint would slow the evaporation of water during
periods of warm weather.
C
Over time, rainwater could react with the surface of the concrete and
deposit a mineral layer over the carved area.
D
When rainwater sits in a concrete basin, the pH becomes too acidic
for the birds. The paint allows the pH to remain neutral.

What process is shown in Keith’s sketch?

Janie gathered four different kinds of rock samples – granite,
limestone, marble, and sandstone. She has 4 trays puts one sample in
each tray. The tray is tilted, the rock sample is placed at the top of the
tray and water is pumped over the rock sample continuously for four
days (96 hours). She checked the samples each day.
25
The purpose of Janie’s
investigation is to determine A
the effects of weathering on
different kinds of rocks
B
C
D
26
27
What is the best way for Janie to
determine the mass of each sample?
A
what kind of rock particles
are suitable for purifying
water
After each day, pour the water
through a filter, and collect the
rock particles. Measure the rock
particles.
B
how changes in the rate of
water flow affect different
kinds of rocks
Measure the dry mass of each
sample before and after each
day.
C
Get the circumference of each
rock sample before starting the
investigation by wrapping a
string around the rocks. Repeat
this measurement after each
day.
D
Capture the water in a separate
container, and measure the
volume after each day.
the effects of pH on different
kinds of rocks
The results of Janie’s
investigation will be useful for F
a sculptor deciding what kind
of rock to use for a
monument.
G
a farmer choosing between
contour farming or terracing
to prevent erosion.
H
a shorefront property owner
wanting to protect his
property from chemical
weathering.
J
a golf course ground keeper
deciding what kind of turf to
plant on the fairways and
greens.

Sand for beaches comes from rocks in the area that are weathered down,
and their sediment is deposited in the area beaches. The beaches are then
eroded, and the sediment is moved away from the beaches. If rocks
stopped weathering, how would the beach change?
30
A
The beach would gain sediment because sand would still be
deposited and not weathered away.
B
The beach would lose sediment because sand would still erode away,
and there is no new sediment being deposited.
C
The beach would stay the same because the beach could not change
if it could not be weathered.
D
The beach would lose sediment because the sand would still weather,
moving sediment into the ocean.
Carbonic acid in rainwater slowly dissolves limestone to form a cave. This is
an example of –
F
chemical weathering
G
mechanical weathering
H
chemical deposition
J
mechanical erosion

The figure shows the original channel of a river, as well as its current
channel.
Which of the following forces MOST LIKELY changed the course of the river?
A
glaciation and eruption
B
deposition and erosion
C
lava flow and weathering
D
crustal uplift and compression
32 Which surface type does wind
erosion most strongly affect?
F
rocks
G
wet, compacted soil
H
loose, sandy soil
J
dry, compacted soil
33
What is the process by which
wind, water, ice, or gravity
transports soil and sediment
from one location to another
called?
A
displacement
B
building
C
erosion
D
mixing

Homes are built on cliffs because of the great views. Sometimes the hills are
built on strong, solid rock, but other times the top rock is lying on top of a weak
rock layer.
Which picture shows how the layers would change as it erodes?

G
H
J

Rivers start in the areas of higher elevation and run towards the ocean. The river
moves sediment, as well as water. When a river is dammed, it will change the
sediment flow of an area. Which change of sediment would be a result of a dam
being built?
A
more sediment would be moved down the river
B
more sediment would be deposited right after the dam
C
more sediment would be deposited in the lake
D
the dam will not affect the deposition of sediment
