Point Vs. Nonpoint 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 wastewater from homes, businesses, or industries is directly discharged into rivers, lakes, or oceans. The sewage contains harmful pollutants such as bacteria, viruses, chemicals, and nutrients that can contaminate the water, harm aquatic life, and pose a risk to human health. It is important to manage and treat sewage properly to prevent this type of pollution and protect the quality of our water resources.

  • 2. 

    When the accumulation of rain flows over the parking lots and roads in North Carolina, it washes pollutants into bodies of water.  How is the 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. These pollutants are not coming from a single identifiable source, but rather from multiple diffuse sources. This type of pollution is known as non-point source pollution, as it cannot be traced back to a specific point of origin.

  • 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 teh landfill

    Correct Answer
    D. Groundwater under teh landfill
    Explanation
    A landfill is most likely to directly pollute the groundwater under the landfill. This is because landfills are designed to collect and contain solid waste, but they often lack proper lining or containment systems. As a result, pollutants from the waste can seep into the soil and contaminate the groundwater below. This can lead to the contamination of drinking water sources and harm ecosystems dependent on the groundwater.

  • 4. 

    Ater pollution is caused by

    • A.

      Runoff from homes

    • B.

      Illegal dumping of waste into a river

    • C.

      Boats on teh river leaking oil

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Water pollution can be caused by 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 chemicals into nearby water bodies. Illegal dumping of waste directly introduces harmful substances into rivers, further polluting the water. Additionally, boats that leak oil contribute to water pollution by releasing hydrocarbons and other toxic substances. Therefore, all of the mentioned factors can contribute to water pollution.

    Rate this question:

  • 5. 

    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 sources and is not easily traceable to a specific location or point of origin. This type of pollution includes runoff from agricultural fields, urban areas, and construction sites, as well as atmospheric deposition. On the other hand, point source pollution refers to pollution that comes from a single identifiable source, such as a factory or sewage treatment plant. Non-point source pollution is considered a larger problem because it is more widespread and harder to control. It can have significant impacts on water quality, ecosystems, and human health.
