  15. T/F: The theoretical layer of life is five miles above and below the ocean's surface.
    True
  16. T/F: Life is equally distributed throughout the biosphere.
    False
  17. T/F: Biomes are based on dominant types of animals which are strongly correlated to whether or not humans are present in the area.
    False
  18. T/F: The seasons are caused by the earth's distance from the sun.
    False
  19. T/F: Warmer air holds more moisture, so areas with warm air tend to have a lot of precipitation.
    True
  20. T/F: Warm air molecules are packed more closely together than cold air, making the air seem warmer.
    False
  21. T/F: The Coriolis effect is influenced strongly by sunspots.
    False
  22. T/F: Tundra biomes are found close to the equator.
    False

    False
  26. T/F: Tropical rainforests and deserts may occur in the same latitude.
    True
  27. T/F: Humans are nitrogen-based life forms.
    False
  28. T/F: The sedimentary cycle refers to calcium, iron, and phosphorus getting leached from sedentary rocks by water erosion.
    True
  29. T/F: Primary succession is the first step of succession.
    True
  30. T/F: A climax community is the final step of succession.
    True
  31. T/F: A spruce tree is an example of a pioneer plant.
    False
  32. T/F: Retrogression in an area can result in fewer species.
    True
  33. Briefly describe what retrogression is.
    When something negative occurs to reduce the diversity of an ecosystem leading to fewer organisms and weakening the food web.
  34. Name at least three things the word climate takes into consideration.

  35. Name two phenomena associated with climatic change.
    • a. Changes in ocean temperature
    • b. Changes in earth 's orbital geometry.
    • c. Volcanic activity with increased atmosphere dust and reduced sunlight penetration.
    • d. Variations in solar radiation.
    • e. Increases in atmospheric gases that absorb hear energy.
  36. What part of the carbon cycle do scientists think is contributing to the greenhouse effect?
    The increase of carbon dioxide due to the burning of forests and fossil fuels.
  37. Briefly describe what retrogression is.
    When something negative occurs to reduce the diversity of an ecosystem leading to fewer organisms and weakening the food web.
