Biomes Intro & Vegetation

Posted on by

Read pp 218-225

  1. Identify which biome we live in and describe the vegetation of the biome
  2. Name the areas in your municipality that you think contain undisturbed natural vegetation. Using Google Maps, estimate (rough) how much of the municipality is undisturbed natural vegetation.  Explain whether or not you think preservation of these areas is necessary.
  3. Using Figure 11.6 (pg 219) as an example, sketch the vegetation profile of:
    • Canada-US border
    • Australia from the northern most point to the southern most point
    • Southern tip of Vietnam to the northern tip of Russia
    • Western most point in Peru to eastern most point of Brazil

*label E-W or N-S and names of biomes

Wind Erosion

Read 271-272 + wind-erosion-effects

  1. How can wind eroded landscapes benefit the economy?
  2. If arid regions are generally dry, why is water considered the chief agent in erosion of these areas? (see pg 269)
  3. What concerns with wind erosion would you have in settling deserts or arid environments?
  4. Explain how humans contribute to increased wind erosion?
  5. What can be done to mitigate wind erosion?
  6. How dangerous is wind erosion to human populations? Explain with evidence from your readings.

Wave Erosion

In groups of 3, record and explain the processes (weathering, erosion, deposition?) involved in the formation of:

  • Longshore drift
  • Spit
  • Bar
  • Stack
  • Tombolo

Define all features (even non-listed ones – cave, arch, lagoon, headland, bay, etc.)

Materials:

  • 1 Grey plastic tray
  • 1 Wooden block
  • Sand (no more than half your tray)
  • Rocks (optional)
  • Water (about 1″ deep)

Homework:

Find at least two references that back up your belief about fracking.

  • Write an open letter to the provincial environment minister or your local MLA to persuade them to encourage or discourage LNG development
  • Discuss the effects on ground water resources
  • Provide links to your sources at the end of your letter
  • Post your letter to your blog

Other sources of groundwater contamination

Fluvial Processes PPT

Red River Case Study:

red-river-case-1

red-river-case-2

red-river-case-3

red-river-case-4

  1. Identify the type of drainage basin.
  2. Where does the Red River drain into?
  3. Use specific characteristics to identify the age type of the Red River.
  4. What type of soil is most common? Explain why.
  5. On the “Pattern of lateral channel migration” map, indicate where there would be erosion, deposition and levees
    • Sketch how this area would look if oxbow lakes were formed
  6. Explain what some appropriate land uses for flood plains would be.
  7. Which flood year was the worst for Winnipeg? Explain why.
  8. See “TOP 10 RED RIVER FLOODS SINCE 1800”, how can you explain why in 1826, the river was only 2 feet higher than in 1852 yet there was an extra 60,000 cubic feet of water whereas between 1996 and 2006, there was a similar rise in the river but only 9000 more cubic feet of water.
    • Why does this make flooding around the Red River more dangerous than an area like Vancouver at the end of the Fraser River?
  9. Explain how floodways on the Red River work to keep Winnipeg safe.
  10. What secondary system is in place to protect the Red River Valley from floods? Explain how it works.
  11. Why would ice mitigation help prevent a flood?
  12. What areas would be affected by flooding of the Fraser? Would Winnipeg’s flood safety plan be necessary for the lower Fraser River? Explain why or why not.

Weathering

Posted on by

*Be prepared for the elements tomorrow!

Read pp 241-248

  1. What is the difference between weathering, erosion and deposition?
  2. How does the hydrosphere affect weathering, erosion and deposition?
  3. List the positives and negatives of degradation to people.
  4. Explain how humans may contribute to weathering (physical and chemical).
  5. Explain how physical weathering could end up increasing the rate of chemical weathering.
  6. What is the relationship between climate and weathering?
  7. Why would crystal growth occur less frequently in humid regions?
  8. Why do soils develop faster and deeper in tropical areas than in cooler, temperate latitudes like southern Canada?
