AGENTS OF EROSION
TAG EARTH SCIENCE
A Webquest
WRITE THIS IN YOUR AGENDA
 Homework for tonight: Complete question strip #4
 Work on your natural wonders /erosion project
 Study your flash cards
 Tomorrow in class we will finish the foldable for section 4. You
do not have to work on it tonight.
IMPORTANT DATES
 Our test over Chapter 12 will be on Wednesday, 11/20. Make
sure to study your flash cards and questions strips and notes
nightly. This will help you prepare for it.
 Natural Wonders/Erosion Project is due on Thursday, 11/21 .
Make sure that you are working on this every night. Do not
wait until the last minute.
ANNOUNCEMENT
 Your test will contain a few questions from topics we have
covered in the past. You will need to review these concepts in
your notebook:
The water cycle
Weathering vs. erosion vs. deposition: what is the difference?
What are the 3 types of rocks and how are they formed?
The rock cycle- intrusive rocks vs. extrusive igneous rocks
What is “topsoil”?
In the metric system, what is the basic unit of length? Mass?
Volume?
 Ice wedging






 (I will post this list again on Edmodo).
DIRECTIONS FOR WEBQUEST
 Follow the directions for each slide. Answer the questions
in complete sentences in your composition notebook on
P. 81. (You can make an 81a, 81b… if necessary)
 Each slide of this Power Point will have links to resources
on the internet about weathering, erosion, and
deposition. Some slides have questions to answer, and
some do not. Read the information on the websites
carefully! Remember, your goal here is to learn, not to
fly though the material on the websites and see how fast
you can answer the questions. 
AGAIN… THIS IS IMPORTANT
 Read the information on the websites carefully! Remember,
your goal here is to learn, not to fly though the material on
the websites and see how fast you can answer the questions.

and air.
NATIONAL GEOGRAPHIC’S PHOTO GALLERY OF
EROSION AND WEATHERING
 Click on the link below to view National Geographic’s Photo
Gallery of Erosion and Weathering.
 You will need to click on the “next” picture after each picture.
Read each caption carefully. (No questions to answer for this,
just enjoy the beautiful pictures! )

Visit the website below. You will start on the slide below and
click through several slides. Carefully read the descriptions and
look at the pictures.
(There are no question s to answer for this. Just read carefully and learn. )

1 . What is the dif ference between weathering and erosion?
Read the information on the two websites below before you
compose your answer. Give a thorough explanation!

just visited this one. Read this one slide again.)

EFFECTS OF EROSION AND DEPOSITON
 2. What are the effects of weathering, erosion, and deposition on
the surface of the Earth ? (In other words, name the ways that
weathering and erosion change the surface of the earth.) Make a
bulleted list. (You will need a lot of room for your answer! You will
keep adding on to your answer as you go through this webquest.)
 View the links and list as many ways possible that weathering,
erosion, and deposition affect the surface of the Earth. As you go
though this Power Point today and visit different websites, you
may add to your list. Below are links to get you started.

H OW DOE S W E ATH ERING A N D E ROSI ON A F F EC T M A N ?
 Carefully read the website below and answer the following
questions: Answer the questions in complete sentences in
your composition notebook.
3. What are landslides? What are other names for landslides?
4. Where can landslides occur?
5. What is the most common type of slide?
6. Which areas are generally prone to landslides?
7. Which areas are generally safe from landslides?
8. Name 5 features that might be noticed before landslides.
(Warning signs)

URBANIZATION AND EROSION
 9. Read the short website below about how construction
(building homes and buildings) can cause erosion without
proper erosion control techniques.
Answer this question: How can urbanization cause erosion?
 ur·ban·i·za·tion- to make (especially a predominantly rural
area or country) more industrialized and urban;
building/construction on a rural area

COOL WEBSITES ABOUT EROSION
 The rest of the slides of this webquest are filled with
wonderful information. There are no questions over the
information, but you are required to participate in viewing the
websites.
 All of the websites support what we have learned in class.
They provide a great visual of the information.
GLACIERS
 Watch the video below about Tracking the Byrd Glacier.

WIND EROSION
Click on the link below to watch videos about wind erosion.

HOW CAVES FORM
 Watch the animation to see how caves form. Be sure to click
on the “Forward” button to advance the animation.

THE GRAND CANYON
What do you get if you mix erosion, volcanoes, a hot and dry
climate and the Colorado River? If you’re really lucky and have
a lot of time – at least a million years – you get the Grand
Canyon. Located in Arizona, this huge hole in the ground shows
the Earth – right down to the bone.
Click on the link below to read more about it. Be sure to watch
the video about the creation of the Grand Canyon!

ADDITIONAL RESOURCES
 Below is an excellent website put together by a college
professor about Erosion.
 Please navigate through it and add any additional information
you need to your questions.
 The section about how Providence Canyon is Georgia was
formed is especially interesting.
