Science - Pollution And Contamination - Quiz

Quiz Preview

  • 2. 

    Water contamination affects our health because it can cause:

    • Liver and Kidney damage

    • Cancer

    • #1 and #2

    Correct Answer
    A. #1 and #2
    Explanation
    Water contamination can have serious health consequences. It can lead to liver and kidney damage, as well as an increased risk of cancer. Contaminants in the water, such as heavy metals and chemicals, can accumulate in the body over time and cause damage to these vital organs. Additionally, certain chemicals found in contaminated water have been linked to an increased risk of developing various types of cancer. Therefore, both liver and kidney damage and an increased risk of cancer are valid reasons why water contamination can affect our health.

    Water Turbidity is caused because:

    • Waste Discharge

    • Residues from an erosion

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Water turbidity is caused by waste discharge and residues from erosion. Waste discharge from industrial and domestic sources can introduce pollutants and suspended particles into the water, making it cloudy and turbid. Similarly, erosion can result in the deposition of sediments and debris into water bodies, further contributing to turbidity. Therefore, both waste discharge and residues from erosion are responsible for causing water turbidity.

    Aeration is the method of:

    • Mixing or forcing air through a liquid

    • Adding a mixture of chemicals into water

    Correct Answer
    A. Mixing or forcing air through a liquid
    Explanation
    Aeration is the process of mixing or forcing air through a liquid. This method is commonly used in wastewater treatment plants to increase the oxygen levels in the water, which promotes the growth of aerobic bacteria that help break down organic matter. Aeration can also be used in aquariums to provide oxygen to the fish and other aquatic organisms. By introducing air into the liquid, aeration helps to improve the quality of the water and ensure the survival of living organisms that depend on it.

    Is Reverse Osmosis a Water Treatment method?

    • Well duh

    • Of course not

    Correct Answer
    A. Well duh
  • 6. 

    What does the term "Urban Runoff" mean?

    • It is the term used to describe a nation collecting contaminants from water

    • Tsunami

    • Water running over areas collecting pollutants as it flows

    Correct Answer
    A. Water running over areas collecting pollutants as it flows
    Explanation
    Urban runoff refers to the process of water flowing over urban areas, such as streets, parking lots, and rooftops, and collecting pollutants along the way. This runoff can include various contaminants like oils, chemicals, fertilizers, and sediment, which are then carried into storm drains, rivers, and ultimately, bodies of water. Urban runoff is a significant source of water pollution and can have detrimental effects on aquatic ecosystems and human health.

    What is the term used to describe the level of transparency of water?

    • Water Turbidity

    • Clear Water

    • Water distillation

    • Disinfection

    Correct Answer
    A. Water Turbidity
    Explanation
    Water turbidity is the term used to describe the level of transparency of water. Turbidity refers to the presence of suspended particles or solids in water, which can cause it to appear cloudy or opaque. The higher the turbidity, the less transparent the water is. This can be caused by various factors such as sediment, algae, or pollutants. Monitoring water turbidity is important in assessing water quality and determining its suitability for various purposes such as drinking, swimming, or aquatic life.

    Final Question! Water Purification is the term used to describe cleaning water. Water Contamination refers to making water impure and unsafe. Aside from the fact that they both have to do with water, what other thing do they have in common?

    • Chemicals - causes contamination and CAN purify water

    • They both involve human activity

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Both water purification and water contamination involve chemicals and human activity. Water purification involves the use of chemicals to remove impurities and make water safe for consumption. On the other hand, water contamination occurs when chemicals or other pollutants are introduced into the water, making it impure and unsafe. Additionally, both processes involve human activity as they are influenced and carried out by human actions and interventions.

    Which of the following processes can be used for water purification?

    • Filtration

    • Chlorination

    • Disinfection

    • All of the above

    • None of the above

    • #1 and #2

    Correct Answer
    A. All of the above
    Explanation
    All of the processes mentioned - filtration, chlorination, and disinfection - can be used for water purification. Filtration involves passing water through a filter to remove impurities. Chlorination is the process of adding chlorine to water to kill bacteria and other microorganisms. Disinfection refers to the use of various methods, such as UV radiation or chemical disinfectants, to kill or inactivate pathogens in water. Therefore, all three processes are effective in purifying water and removing contaminants.

    Why is Reverse Osmosis not a preferred method to clean water?

    • Fairly slow

    • Expensive

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Reverse osmosis is not a preferred method to clean water because it is fairly slow and expensive. Reverse osmosis involves pushing water through a semipermeable membrane to remove impurities, which takes time and slows down the overall process. Additionally, the equipment and maintenance required for reverse osmosis can be costly, making it a less preferred option compared to other more efficient and cost-effective methods of water purification.

    Water contamination falls into the following two categories:

    • Nutrient and Bacterial

    • Biological and Chemical

    • Osmosis and Diffusion

    Correct Answer
    A. Biological and Chemical
    Explanation
    Water contamination can be categorized into two types: biological and chemical. Biological contamination refers to the presence of microorganisms such as bacteria, viruses, and parasites in water, which can cause various diseases. Chemical contamination, on the other hand, involves the presence of harmful substances such as heavy metals, pesticides, and industrial pollutants in water, which can have adverse effects on human health and the environment. Both types of contamination are significant concerns as they can lead to waterborne illnesses and environmental degradation.

    What are the three types of water pollution?

    • Bacterial, Runoff, Chemical

    • Sediment, Nutrient, Bacterial

    • Contamination, Turbidity, Transparency

    Correct Answer
    A. Sediment, Nutrient, Bacterial
    Explanation
    The three types of water pollution are sediment, nutrient, and bacterial. Sediment pollution occurs when soil and other particles are washed into bodies of water, causing them to become cloudy and murky. Nutrient pollution refers to the excessive presence of nutrients, such as nitrogen and phosphorus, in water bodies, which can lead to harmful algal blooms and oxygen depletion. Bacterial pollution is caused by the presence of harmful bacteria, such as E. coli, in water sources, which can pose a risk to human health.

    Bonus: Turbidity refers to the transparency of water. What unit do we use to measure Turbidity?

    • Nephelometric Transparency Unit

    • Turbidity Transparency Unit

    • Nitro Terbidometer Unit

    • Nephelometric Turbidity Unit

    Correct Answer
    A. Nephelometric Turbidity Unit
    Explanation
    Turbidity refers to the cloudiness or haziness of a liquid caused by suspended particles. The unit used to measure turbidity is the Nephelometric Turbidity Unit (NTU). This unit is based on the principle of nephelometry, which measures the scattering of light by suspended particles in the water. The higher the NTU value, the more turbid or cloudy the water is. Therefore, the correct answer is Nephelometric Turbidity Unit.
