Soils


 

Read Pg 226-236:

  1. Sketch the results of your soil texture lab with the percentages of each particle size. Use the soil texture pyramid on pg 227 to find out what type of texture the soil is.
  2. Based on the soil texture from question 1, what types of plants would thrive in these soils? What would need to be done to make the soil appropriate for agriculture?
  3. Explain how climate (precipitation and temperature) affects soil types and how that affects plant adaptation.
  4. What type of soil would you expect to find here in BC? Explain the properties of the soil and soil profile you would expect. What other countries share the same soil type/profile?
  5. Name the types of soils natural to Canada and where they are. What needs to be done to each to make it suitable for agriculture?

Biomes Intro & Vegetation

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

Us and Climate

Read pages 72-77, 80-84 in Understanding Our Environment

How we affect climate chart

 

Review pages 162-163, 324-335, 349-353 in Planet Earth

Task: Between Global Climate Change, Ozone Depletion, and Acid Precipitation, which issue should the world be focused on? Explain by assessing:

  1. How easy it would be for humans to change their habits to positively affect the issue
  2. What’s in place already that is helping the issue
  3. How dangerous to human life the issue is

Climate and Us

BC GDP by Industry

BC Employment by Industry

 

  1. Find any two country’s data for GDP and Employment by Industry, post the links to the data and determine which industries are most affected by climate.  Explain how climate affects these industry and provide the proportion of employment and GDP the industries represent.
  2. Between BC and the two countries you researched, which region’s economy would be most affected by global warming? Explain how you made your conclusion.

Precipitation

Pages 197-207

  1. Explain whether or not the hydrologic cycle is a open or closed cascading system.
  2. Use the list of storehouses on page 197 and explain what would happen if each of them experienced increased solar radiation.
    • Would the increased solar radiation have an overall positive or negative effect on the earth?
    • How would your answer above be different if insolation did not change but atmospheric temperatures increased (Global Warming)?
  3. Of the different storehouses, which one poses the largest possible risk to people if it depleted? Explain why.
  4. How does human development (buildings, roads, farms, cities) affect the hydrologic cycle?
  5. What conditions are needed for clouds to form?
  6. Why is it safer to drink lake water than ocean water?
  7. What would you look for in the sky to see if a warm front is coming?
  8. What kinds of clouds are most common in the Lower Mainland? Explain why.
  9. Use your knowledge of wind and precipitation to explain why the Pacific Northwest “rains all year long”. Explain what happens in the summer and winter.
