Questions and Answers
  • 1. 

    When runoff crosses the land, it picks up fertilizers that have been used on crops and lawns. These contaminants will eventually enter a lake, river or stream, which may lead to -

    • A.

      The earth’s surface to sink.

    • B.

      The water in an aquifer to drop.

    • C.

      Harmful over-growth of algae

    • D.

      Clean water for drinking and bathing

    Correct Answer
    C. Harmful over-growth of algae
    Explanation
    Runoff from land carries fertilizers that have been used on crops and lawns. These fertilizers contain nutrients such as phosphorus and nitrogen. When these nutrients enter a lake, river, or stream, they can cause an overgrowth of algae. This overgrowth is harmful because it can deplete oxygen levels in the water, leading to the death of other aquatic organisms. It can also create harmful algal blooms that produce toxins, making the water unsafe for drinking and bathing. Therefore, the presence of fertilizers in runoff can result in a harmful overgrowth of algae in water bodies.

    A student builds a model to show how pollutants move through an ecosystem. In plastic tub, the student places a layer of small marbles, covers it with a thick cloth, and then adds a layer of sand. The student then sprinkles red powdered paint on top of the soil. When the student sprays water onto the model, red color appears in the cloth and in the water in the layer of marbles. Which part of the model represents pollutants introduced by humans?

    • A.

      The marbles

    • B.

      The thick cloth

    • C.

      Red powdered paint

    • D.

      Layer of sand

    Correct Answer
    C. Red powdered paint
    Explanation
    The red powdered paint represents pollutants introduced by humans because it is the substance that is being sprayed onto the model by the student. The paint is meant to simulate pollutants in the ecosystem, and its presence in the water and cloth indicates that it is being transported through the system. The marbles, thick cloth, and layer of sand are all components of the model but do not directly represent pollutants introduced by humans.

    • C.

      Closest to a freshwater stream or river

    • D.

      Nearest to the main street of the village

    B. Downstream from the village
    Explanation
    The paper play mill needs to be downstream from the village, so when it rains any pollution in the water will not flow into the village

    The illustration provided shows a river and four cities on that river. When the water from the river was sampled at location X, it was determined to be polluted with various chemicals. What would be the most likely source for this pollution?

    • A.

      City 1 and City 2

    • B.

      City 2 and City 3

    • C.

      City 3 and City 4

    • D.

      City 1 and City 4

    Correct Answer
    A. City 1 and City 2
    Explanation
    The most likely source of pollution in the river at location X would be City 1 and City 2. This can be inferred because the question states that the water from the river was sampled at location X and found to be polluted with various chemicals. Since City 1 and City 2 are the only cities that share a common point on the river, it is likely that their waste or discharge is polluting the river at that location.
