Questions and Answers
  • 1. 

    How much of the water on earth is available to drink?

    • A.

      95%

    • B.

      26%

    • C.

      0.3%

    Correct Answer
    C. 0.3%
    Explanation
    Approximately 97.5% of the Earth's water is in the form of saltwater in the oceans and seas, making it unsuitable for drinking or irrigation without desalination. Only about 2.5% of the Earth's water is freshwater, and the majority of this freshwater, roughly 68.7%, is locked in ice caps and glaciers. Additionally, a significant portion is underground or in the form of soil moisture. This leaves only a small fraction, estimated to be around 0.3% of the Earth's total water, as surface freshwater in lakes, rivers, and swamps, which is more readily accessible for drinking and other human uses. However, not all of this 0.3% is easily accessible or safe to drink without treatment, which underscores the importance of water conservation and responsible management.

    AFC Buildings Water Consumption Target.

    • A.

      999 ltr/man/month

    • B.

      1000 ltr/man/month

    • C.

      2000 ltr/man/month

    Correct Answer
    B. 1000 ltr/man/month
    Explanation
    The correct answer is 1000 ltr/man/month. This suggests that the target for water consumption in AFC Buildings is 1000 liters per person per month.

  • 3. 

    Which of the following uses the most water?

    • A.

      Washing the car

    • B.

      Doing a load of laundry

    • C.

      Having a bath/shower

    Correct Answer
    C. Having a bath/shower
    Explanation
    Having a bath/shower uses the most water compared to washing the car or doing a load of laundry. This is because when taking a bath or shower, the water continuously flows for a longer period of time. In contrast, washing a car or doing a load of laundry requires a one-time use of water, which is generally less than the amount used during bathing. Therefore, having a bath/shower consumes the highest amount of water.

    When is the World Water Day?

    • A.

      March 22

    • B.

      April 21

    • C.

      December 20

    Correct Answer
    A. March 22
    Explanation
    World Water Day is observed on March 22nd each year. This day is dedicated to raising awareness about the importance of freshwater and advocating for the sustainable management of water resources. It serves as an opportunity to highlight the global water crisis and promote actions to address water-related issues. By celebrating World Water Day on March 22nd, organizations and individuals worldwide can come together to educate, inspire, and take action towards achieving water security for all.

  • 5. 

    How much percentage of the world's total freshwater is present in the Middle Eastern countries?

    • A.

      1%

    • B.

      3%

    • C.

      10%

    Correct Answer
    A. 1%
    Explanation
    Only 1% of the world's total freshwater is present in the Middle Eastern countries. This indicates that the Middle East has a very limited supply of freshwater compared to the rest of the world. The region is known for its arid and desert landscapes, which contribute to the scarcity of freshwater resources. This low percentage highlights the challenges that Middle Eastern countries face in terms of water scarcity and the need for efficient water management strategies.

  • 6. 

    The correct symbol for water is?

    • A.

      HO2

    • B.

      H2O

    • C.

      CH4

    Correct Answer
    B. H2O
    Explanation
    The correct symbol for water is H2O. This is because water is composed of two hydrogen atoms (H2) bonded to one oxygen atom (O), forming the chemical formula H2O.

  • 7. 

    The journey water takes as it circulates from the land to the sky and back again.

    • A.

      Hydrologic cycle

    • B.

      Nitrogen Cycle

    • C.

      Condensation Cycle

    Correct Answer
    A. Hydrologic cycle
    Explanation
    The hydrologic cycle refers to the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and runoff, through which water circulates from the land to the sky and back again. This cycle is crucial for maintaining the Earth's water balance and ensuring the availability of water for various ecosystems and human activities. The nitrogen cycle and condensation cycle are not specifically related to the journey of water as described in the question.

  • 8. 

    Of the following indications of the health of a water body, which is the most widely accepted means of measuring how polluting an effuent is?

    • A.

      BOD (biological oxygen demand)

    • B.

      COD (chemical oxygen demand)

    • C.

      Chloroform content

    Correct Answer
    A. BOD (biological oxygen demand)
    Explanation
    BOD (biological oxygen demand) is the most widely accepted means of measuring how polluting an effluent is. BOD measures the amount of dissolved oxygen that is consumed by microorganisms in the water to decompose organic matter. Higher BOD levels indicate higher levels of organic pollution, as more oxygen is needed to break down the organic materials. COD (chemical oxygen demand) is another measure of water pollution, but it includes both biodegradable and non-biodegradable organic matter, making BOD a more specific indicator of pollution. Chloroform content is not directly related to the measurement of pollution in water bodies.

    What is electricity made from moving water called?

    • A.

      Hydroelectricity

    • B.

      Thermal Electricity

    • C.

      Tidal Power

    Correct Answer
    A. Hydroelectricity
    Explanation
    Hydroelectricity is the correct answer because it refers to the electricity that is generated by harnessing the power of moving water, usually from rivers or dams. This process involves the use of turbines to convert the kinetic energy of the water into electrical energy. Thermal electricity refers to the electricity generated from the heat energy of burning fossil fuels, while tidal power refers specifically to the electricity generated from the rise and fall of tides.

  • 10. 

    The process remove some amount of salt and other minerals from saline water called?

    • A.

      Desalination

    • B.

      Eutrophication

    • C.

      Biomagnification

    Correct Answer
    A. Desalination
    Explanation
    Desalination is the correct answer because it refers to the process of removing salt and other minerals from saline water. This process is commonly used to make seawater drinkable, as well as to produce freshwater for irrigation and industrial purposes. Desalination can be achieved through various methods such as reverse osmosis, distillation, and electrodialysis.
