1. Teaching Notes: Unit & Lesson Slides
• The content, vocabulary, videos and activities shown on the following slides come
directly from your student and teacher text. PDFs are referenced on slides and
can be downloaded by teachers and students online at Ed: Your Friend in Learning
(Ed: YFIL)
• All slide content is editable, as you may add, remove or edit content to meet your
individual classroom needs.
• Many slides include notes such as: the Performance Expectations, Anchor
Phenomenon, lesson objectives, building on prior knowledge, lab notes.
• It is recommended that students utilize an evidence notebook as they ask
questions, collect evidence and data throughout the lessons. This will help them
with sense-making of the Anchor Phenomenon. Look for the notebook icon on the
first and last slide of each lesson as a reminder.
o Support for Evidence Notebooks can be found in the front of your
Teacher Edition, and prompts will be shown in the student text throughout
each lesson.

2. Teaching Notes: Using Unit & Lesson Slides
• It is recommended you play/present
slides when using for instruction.
• Note: Some videos may not play with
Google Slides. All videos can be found in
the Student & Teacher eBooks
• Slides that contain animations will have
content that is initially hidden and
revealed with click in play/presenter
view. You can see all slide content in
normal view.
• To manage animations:
– Open in PowerPoint
– Click Animations
– Click Animation Pane

Unit 1: The Dynamic Earth
Lesson 1: Weathering, Erosion, and
Deposition

5. 5
ELD Language Support
Lesson Vocabulary
• weathering —process by which rock materials are broken
down by the action of physical and chemical processes
• sediment — fragments of weathered rock
• erosion — process by which wind, water, ice, or gravity
transport weathered materials from one location to another
• deposition — process by which eroded materials are
dropped, or laid down
ELL/ELD Strategy
Combination Notes Synthesize key topics by taking
Combination Notes as you read each section. These notes will
help you better understand weathering, sediment, erosion, and
deposition.

What caused these changes at Port Campbell National
Park?
Earth’s surface can change quickly, or
so it seems. The photograph on the
top shows a rock formation just
offshore of Port Campbell National
Park in Australia before 1990. The
photo on the bottom shows the same
rock formation after 1990.
Mod F Unit 1 Lesson 1

7. • Rocks and other Earth materials
can be changed.
• Weathering is the process by
which rock materials are broken
down by the action of physical
and chemical processes.
• Fragments of weathered rock
called sediment are an
important part of soil
• Some rocks are more resistant to
weathering than other rocks.

Identifying Effects of Weathering
Mod F Unit 1 Lesson 1

8. 8
Identifying Effects of Weathering
• The two main types of
weathering are physical
and chemical.
• Physical weathering is
mechanical breakdown
rocks into smaller pieces.
• Rocks can be physically weathered by temperature
changes, as well as interactions with plants, animals, water,
wind, ice, and gravity.
Mod F Unit 1 Lesson 1
Physical Weathering

9. 9
Identifying Effects of Weathering
• Chemical weathering is the
breakdown and decomposition
of rocks due to chemical reactions.
• Chemical weathering changes to
composition of rocks.
• Agents of chemical weathering include air, water, and plants
• Underground caves form as water containing natural acids
flow through rock below Earth’s surface.

Chemical Weathering

10. 10
Does the collapsed rock formation in Australia show signs of
weathering? If so, identify the type of weathering that could
have occurred. Record your evidence.

11. • Erosion is the process
by which wind, water,
ice, or gravity carry
weathered material
from one place to
another.
• Deposition occurs
when eroded material
are laid down on a
location.

Exploring Agents of Erosion and Deposition
Mod F Unit 1 Lesson 1

12. • Wind and water cause
weathering through abrasion.
• Water erodes rocks on Earth’s
surface, as well as below the surface.
• On the surface, waves and running water carve away at
rocks along rivers and coastlines.
• Wind blows away sediments and can also abrade some
rock formations.
• When moving wind and water lose energy, they slow down
and deposit sediments in new locations.

13. 13
Exploring Agents of Erosion and Deposition
• Ice is a powerful agent of
erosion and deposition.
• A glacier is a large mass of
ice that exists year-round.
It moves slowly over land,
and large amounts of soil, sediment, and rock are eroded
and moved to distant locations.
• The force of gravity pulls all matter toward Earth’s center
causing rocks, boulders, soil, and even water to flow
downhill.
• Gravity is responsible for rapid changes to Earth’s surface
caused by landslides and rock falls.

Will gravity always play a role in erosion of a shoreline
feature, such as the collapse of a rock formation in Australia?
If so, identify the process, or processes, that would lead up to
the collapse. Record your evidence.

Modeling Weathering, Erosion, and
Deposition
• You cannot re-create natural phenomenon such as
weathering, erosion, and deposition in the lab, but you
can use models to help recreate past events and predict
future ones.
• Maps and computer models
can show how and where
events occurred.
Mod F Unit 1 Lesson 1

17. 17
HANDS-ON LAB
Model Erosion and Deposition
You will model Earth’s surface
with sand to investigate the
Effects of erosion and deposition
by wind and water. Then you
will make prediction about the
effects of different agents on
erosion and deposition.
See the Student eBook for a downloadable worksheet or
page 15 for ideas to help you get started.

TAKE IT FURTHER
Gold Rush
Can you use your knowledge
of erosion and deposition to
become rich? Gold prospectors know
that deposition occurs when water
slows down and loses energy.
Weathering can wear away layers of
rock, exposing gold nuggets. Erosion
carries them into streambeds. Deposition
drops the nuggets where the water slows down.
Discuss with a classmate where you would search. Did you identify
the same places? Together, decide on which location you would
search first and argue from evidence to support your decision.

Can You Explain It?
Refer to your notes in your
Evidence Notebook to help
you construct an
explanation of the causes of
the changes at Port
Campbell National Park.
• State your claim. Make sure your claim fully explains
how changes at Port Campbell National Park occurred.
• Summarize the evidence you have gathered to support
your findings and explain your reasoning.
