  • Q1
    In the 1930s, the American Great Plains became known as the Dust Bowl because it was the source of huge clouds of dust that covered much of the United States. Which BEST describes the causes of the Dust Bowl?
    a severe drought and the overuse of prairie farmland.
    wide-scale deforestation and gradual climate change
    the overuse of fossil fuels and extensive crop rotation.
    a long period of cool weather and a volcanic eruption
  • Q2
    Some used car oil was put in a container to take to a mechanic for proper disposal. The used oil is disposed of this way so that
    the oil can be reused in other cars
    impurities in the oil can be studied to improve car engine design
    the oil can be recycled to protect the environment
    the total amount of oil used by car owners will not increase
  • Q3
    Around the edges of many dry areas, local plant life helps to create cool, moist conditions. When humans deplete these areas of vegetation, the areas become drier and soil rapidly disappears. Which characteristic of plants in these areas MOST likely helps to prevent soil erosion?
    pollination cycles
    root systems
    release of moisture from leaves
    photosynthetic activites
  • Q4
    The graph show the temperature of the ocean's surface since 1960. Suppose this trend continues. What prediction about hurricanes is BEST supported by the data?
    Question Image
    Hurricanes will likely be more powerful and more frequent.
    Hurricanes will likely be less powerful but more frequent.
    Hurricanes will likely be more powerful but less frequent.
    Hurricanes will likely be less powerful and less frequent.
  • Q5
    Trees are carbon sinks, because they absorb and store carbon dioxide from the atmosphere during photosynthesis. Burning large stands of rainforest not only reduces the amount of photosynthesis on Earth, but it releases carbon back into the atmosphere as carbon dioxide gas. Carbon dioxide levels in the ocean are directly correlated to carbon dioxide levels in the atmosphere. What would be the MOST likely effect of burning large stands of rainforest?
    The ocean water would become more acidic.
    The ocean water would become more alkaline.
    The ocean water would dissolve gases more easily.
    The ocean water would dissolve gases less easily.
  • Q6
    One biome includes bearberry, a short plant with small, waxy leaves, shallow roots, and flowers that bloom quickly in the short growing season. Another biome includes tall grasses that can survive fires due to roots that extend 6 to 7 meters deep during the long growing season. What is MOST likely true about the two biomes?
    They are at different latitudes but have the same temperature range.
    The have the same temperature range but different rainfall ranges.
    They have the same temperature range and the same rainfall range.
    The are at different latitudes and have different temperature ranges.
  • Q7
    Nonnative flathead catfish that prey on smaller fish were accidentally introduced into the Yadkin River in North Carolina. What is the MOST likely effect these catfish could have on the ecology of the Yadkin River?
    They could reduce native fish populations.
    They could decrease water flow in the river.
    They could increase pollution in the water.
    They could damage streambeds and shoreline.
  • Q8
    Leafcutter ants live in South and Central American tropical rainforests. Their huge, underground colonies contain an average of 5 million individuals. These ants have a complex society that includes a queen, workers, and soldiers. Leafcutter ants tend fungus gardens within their colony to feed to their larvae. The ants keep the fungus alive by feeding it fresh plant material. How does a leafcutter ant colony help to support the tropical rainforest biome?
    The colony removes dead leaves from trees and other plants.
    The colony removes fungi from trees and the forest floor.
    The colony recycles nutrients back to the soil for plants to use.
    The colony clears the forest floor of living plant material.
  • Q9
    What is the carrying capacity of an ecosystem?
    the maximum number of individuals that an ecosystem can support without harming the ecosystem.
    the minimum number of individuals needed to have balance in an ecosystem
    the total number of individuals, living and dead, that have been supported by an ecosystem
    the total number of organisms alive at the same time in an ecosystem
  • Q10
    Study the information in the table. Which additional piece of information would be MOST helpful in evaluating the impact of acquiring each energy resource?
    Question Image
    the names of the organisms harmed by each form of resource acquisition
    the relative energy densities of each resource
    the number of power plants using each resource
    the scale of the impact from each kind of energy resource
  • Q11
    The table lists some ways that plants have adapted to survive in a desert biome. Which statements describe adaptations to biotic factors in a plant's desert biome?
    Question Image
    2 and 4
    3 and 4
    1 and 2
    1 and 3
  • Q12
    A lemming population lives in a cold, mountainous region. Over time, the climate in the region becomes drier and warmer. The lemming population would be MOST likely to adapt and remain in the area under these new climate conditions if individuals in the population developed this characteristic.
    sharp teeth
    large size
    small ears
    short fur
  • Q13
    Sweet potatoes grow best in sandy, well-drained soil. In which North Carolina ecological region would you MOST likely grow sweet potatoes?
    coastal plain
  • Q14
    What do the energy resources uranium and coal have in common?
    They both are acquired by mining the lithosphere.
    They both generate radioactive wastes.
    They both are formed from the remains of dead organisms.
    They both release energy through combustion.
  • Q15
    What is an environmental threat posed by oil and gas acquisition and transport that is NOT posed by the acquisition and transport of the energy resources uranium, and wood?
    vehicle pollution
    habitat change
    pipeline leaks
    soil compaction and loss
