Station 3
Wave Erosion
Procedure
1. Place some sand on one side of the tray.
2. Gently pour some water in the remaining portion of the tray so that the level of the water is
below the level of the sand.
3. Create gently waves by moving the pan slowly from side to side. DO NOT move it hard enough to
spill water everywhere.
4. Write a description of what is happening to the sand and rocks.

Wind Erosion
Procedure
1. Place some sand on one side of the tray.
2. Arrange the small rocks on top of the layer of sand.
3. Using a straw, blow gently on the sand an rocks and observe how they move. Do not blow hard
enough to get sand all over the table or in another person’s eye. Do Not share straws!
3. Which rocks were you able to move by blowing on the sand? _____________________________

27 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.
28 Keith made the sketch above during a field investigation on weathering. What
process is shown in Keith’s sketch?
F abrasion
G chemical weathering
H ice wedging
J mineral separation

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.
29 The purpose of Janie’s investigation is to
determine A the effects of weathering on different
kinds of rocks
B what kind of rock particles are suitable
for purifying water
C how changes in the rate of water flow
affect different kinds of rocks
D the effects of pH on different kinds of
rocks
31 What is the best way for Janie to
determine the mass of each sample?
A After each day, pour the water through
a filter, and collect the rock particles.
Measure the rock particles.
B 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.
30 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.

32 After Janie determines the mass of each rock sample, which data table should she use to
record her data?
33 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

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?
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.

C
