Point Vs Non-point Source Pollution Notes Quiz - Quiz


Questions and Answers
  • 1. 

    What is an example of point-source pollution?

    • A.

      Chemical runoff from roads

    • B.

      Beach trash that gets into the water

    • C.

      Sewage pipes draining into bodies of water

    • D.

      Fertilizer from lawns seeping into groundwater

    Correct Answer
    C. Sewage pipes draining into bodies of water
    Explanation
    Sewage pipes draining into bodies of water is an example of point-source pollution. This occurs when untreated or partially treated sewage is directly discharged into rivers, lakes, or oceans. It can lead to water contamination, harmful algal blooms, depletion of oxygen levels, and negative impacts on aquatic ecosystems. Sewage contains various pollutants, including bacteria, viruses, nutrients, and chemicals, which can pose a threat to both human health and the environment.

    When the accumulation of rain flows over parking lots and roads in North Carolina, it washes pollutants into bodies of water.  How is this pollution classified?

    • A.

      Primary

    • B.

      Secondary

    • C.

      Point source

    • D.

      Non-point source

    Correct Answer
    D. Non-point source
    Explanation
    When rainwater flows over parking lots and roads, it picks up pollutants such as oil, chemicals, and debris. This runoff is considered non-point source pollution because it does not come from a specific, identifiable source. Unlike point source pollution which comes from a single, identifiable source like a factory or sewage treatment plant, non-point source pollution is diffuse and comes from many different sources. It is challenging to control and manage non-point source pollution because it comes from various activities and areas, making it harder to regulate and mitigate its effects on bodies of water.

    Rate this question:

  • 3. 

    A landfill is most likely to directly pollute

    • A.

      Water vapor over the landfill

    • B.

      Precipitation about to fall on the landfill

    • C.

      Surface streams flowing to the landfill

    • D.

      Groundwater under the landfill

    Correct Answer
    D. Groundwater under the landfill
    Explanation
    A landfill is most likely to directly pollute groundwater under the landfill. Landfills are designed to contain waste materials, but they are not completely impermeable. As rainwater and other liquids seep through the landfill, they can pick up pollutants from the waste and contaminate the groundwater below. This polluted groundwater can then flow into nearby wells or surface water bodies, posing a risk to human health and the environment.

    Rate this question:

  • 4. 

    Water pollution is caused by

    • A.

      Runoff from homes

    • B.

      Illegal dumping of waste into a river

    • C.

      Boats on the river leaking oil

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Water pollution can occur due to various factors, including runoff from homes, illegal dumping of waste into a river, and boats on the river leaking oil. Runoff from homes can carry pollutants such as fertilizers, pesticides, and household chemicals into nearby water bodies. Illegal dumping of waste directly releases harmful substances into the water, leading to pollution. Additionally, boats leaking oil can introduce toxic substances into the water, further contributing to water pollution. Therefore, all of the mentioned factors can cause water pollution.

    Rate this question:

  • 5. 

    True or false: Non-point source pollution is a larger problem than point source pollution.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Non-point source pollution refers to pollution that comes from multiple, diffuse sources, such as runoff from agricultural fields or urban areas. On the other hand, point source pollution comes from a single, identifiable source, such as a factory or wastewater treatment plant. The given answer, "True," suggests that non-point source pollution is a larger problem than point source pollution. This is because non-point source pollution is more widespread and harder to regulate and control compared to point source pollution, which can be more easily monitored and managed.
