3: climate, soil, natural vegetation

Which of the following is not typical of maritime climates?

• a relatively small annual temperature range

  
  

• relatively cool summers

  
  

• relatively high annual precipitation

  
  

• relatively mild winters

  
  

• convectional precipitation

  
  

Which of the following wind belts/pressure systems is likely to have the greatest impact on most of Canada?

• equatorial low

  
  

• polar easterlies

  
  

• northeast trades

  
  

• westerlies

  
  

• southeast trades

  
  

Which of the following is not a climate region of Canada?

• Taiga

• Pacific maritime

  
  

• Southeastern boreal

  
  

• Arctic

• Cordilleran

Soil develops from a thick, loose layer of

• nutrient rock

  
  

• humus

• parent material

  
  

• mineralized rock

  
  

• surface deposits

  
  

Tundra soils drain poorly and are waterlogged because

• of air that is missing from the soil's profile

  
  

• the cool growing season limits plant growth

  
  

• they are very thin

  
  

• the permafrost does not allow water to drain downward

  
  

• of the slow breakdown of organic materials into humus

  
  

The most northerly vegetation region of Canada

• mixed forest

  
  

• cordilleran vegetation

  
  

• taiga forest

  
  

• tundra

  
  

• boreal forest

  
  

The vegetation region that is considered a transition zone between boreal and deciduous forest

• grassland

• tundra

• mixed forest

  
  

• boreal forest

  
  

• deciduous forest

  
  

The smallest vegetation region in Canada

• grassland

• deciduous forest

  
  

• cordilleran vegetation

  
  

• mixed forest

  
  

• boreal and taiga forest

  
  

Only a small part of Canada’s deciduous forest remains because

• it is the northernmost part of the deciduous forest region of the United States

  
  

• it has been slowly dying from air pollution

  
  

• it has been cleared for farming and urban growth

  
  

• most deciduous trees need at least five months of average temperatures above 10⁰ C

  
  

• the heavy snowfalls in winter have broken the trees' branches

  
  

The type of vegetation found in a warm, dry climate

• dense forest

  
  

• tundra

• deciduous forest

  
  

• maple, oak, beech, and elm trees

  
  

• grasses
