Physical Geography

~The WEAR and TEAR of the Earth~


Important concepts you should know:

  • understand how tectonic forces and gradational forces work in balance to create landscapes
  • be able to explain the processes involved in folding, faulting and denudation
  • critically analyze the conflict between public and private interests in land use conflict

A.    Folding and Faulting

  1. Click here for an introductory show that describes the processes involved in the Wear and Tear of our Earth.
  2. View some more pictures by clicking on:  http://darkwing.uoregon.edu/%7Emillerm/faults.html.
  3. Click here for a slide show on Rock Deformation.
     
    • What are the two main different types of folding?
    • How can you distinguish between the two?
    • During what stage of deformation does folding occur?
    • During what stage does faulting occur?
    • How do the plastic and elastic stages differ?
    • True or false:  Brittle rock will most likely rupture before it reaches the plastic stage.  Explain
    • Would you consider a rock with a crystalline structure to be more brittle or ductile?  Explain
       

Book Work - Chapter 5 "Movers and Shakers: How Landforms are created" pages 62-73

  1. In the Developing Skills section "Interpreting Contour Maps" on page 72 - read and do the "Practise It" , Parts 1 and 2.
  2. Do #1, 2, 3 5a(use page 64/65), 7, 13, 15

B.    Denudation

  1. Click here for an introduction to the forces of denudation (Degradation Processes: Mechanical/Chemical) 
  2. Click here to see a Flash movie about Karst Topography.
  3. Click here to see a Flash movie on how a Sink Hole is formed.
  4. Click here to go to a website with great pictures of the various forces of degradation.  
  5. Watch the slideshow on weathering processes and associated landscapes for clarification.
  6. Click here for a slide show on Mass Wasting.
  7. View a short video on mudslide development.
  8. Check out Mrs. Beukeboom's research on Mass Wasting due to the quick/sensitive Tyrrell Sea clay
    in the Hudson Bay Lowlands

C.    Frank Slide Activity

  1. Click here to go to the page that outlines this activity. There are 2 parts to the activity:
    • PART 1: Report on what occurred in Frank, Alberta
    • PART 2: Lab Activity: Calculating the Affected Area
       
  2. Click here to read an article about a series of avalanches last year. Answer the following questions:

    a. What happened?
    b. Where did it happen and be able to locate it on a map?
    c. What were the causes of this avalanche?
    d. Are there some preventions or predictions that people can use to avoid these disasters?
    e. Why do you think the avalanches are not occurring as much this year? Make some predictions.

D.    The Niagara Escarpment

  1. Take a look at the Niagara Escarpment aerial photograph.  Can you figure out what each number represents?
  2. Listen carefully in class for an overview of the formation of the Niagara Escarpment.
  3. Follow the link below to find out more about the geology of the Niagara Escarpment.  Explain the geologic history of the formation of the escarpment.

    http://www.escarpment.org/home/index.php - click around!

        -  Why are the Niagara Falls where they are today?
        -  Write down all the familiar words you come across.  ie. Talus.
        -  Can you determine how the terms anticline and syncline are involved in the formation of the escarpment?

The "Jigsaw" activity on the Niagara Escarpment

  1. Click here to go to a "jigsaw" exercise that will involve a collaborative study of the Niagara Escarpment.  
    • Mind web (graphic organizer) - 1 for Overview and 1 for Interests = 2 mind webs.
    • Each expert group will present their area of expertise to the class instead of going back to your groups and sharing.  It is important you listen to the group presentations as the information is fair game for a test/quiz.
    • You will be evaluated on group performance, accuracy and detail of your presentation (content), individual participation within the group.
