The Natural Resources MCQ Quiz: Trivia

Natural resources are entities that occur naturally, such as freshwater and even gasses. Some of the most dominant gases in the atmosphere are nitrogen and oxygen. Do you know the processes these gases undergo once presented into the environment? This quiz will shed some light on it. Do give it a shot and see what new information you might learn. All the best!


Questions and Answers
  • 1. 
    What would happen, if all the oxygen present in the environment is converted to ozone?
    • A. 

      We will be protected more

    • B. 

      It will become poisonous and kill living forms

    • C. 

      Ozone is not stable, hence it will be toxic

    • D. 

      It will help harmful sun radiations to reach earth and damage many life forms

  • 2. 
    When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of nitrogen?
    • A. 

      It moves along with oxygen into the cells

    • B. 

      It comes out with the carbon dioxide during exhalation

    • C. 

      It is absorbed only by the nasal cells

    • D. 

      Nitrogen concentration is already more in the cells, so it is not at all absorbed

  • 3. 
    There is always a cycle of CO2 running in the atmosphere due to which the concentration of CO2 remains constant in the atmosphere. Choose the correct sequence of this cycle:
    • A. 
    • B. 
    • C. 
    • D. 
  • 4. 
    You must have observed that during the winters  sometimes it becomes quite difficult to see even the objects  short distance apart. This low visibility during the cold weather is due to:
    • A. 

      Formation of fossil fuels

    • B. 

      Unburnt carbon particles of hydrocarbons suspended in air

    • C. 

      Lack of adequate power supply

    • D. 

      None of these

  • 5. 
    ‘ Water pollution’ can be defined in several ways. Which of the following statements does not give the correct definition?
    • A. 

      The addition of the undesirable substances to water bodies

    • B. 

      The removal of the desirable substances from water bodies

    • C. 

      A change in pressure of the water bodies

    • D. 

      A change in temperature of the water bodies

  • 6. 
    The amount of nitrogen in the atmosphere is maintained by a biological cycle which involves two processes, first is to withdraw nitrogen from the atmosphere and secondly to add the same to the atmosphere.                                            The nitrogen cycle can you guess the names of these two respective processes?
    • A. 

      Nitrogen fixation and nitrification

    • B. 

      Nitrogen fixation and denitrification

    • C. 

      Nitrification and denitrification

    • D. 

      Nitrification and nitrogen fixation

  • 7. 
    The ozone layer is a protective blanket in the atmosphere that protects us from the harmful high energy UV radiation coming from the sun. But it has been observed that some harmful air pollutants like chlorofluorocarbons are causing a hole in this protective layer. What does this ‘ozone hole’ exactly mean?
    • A. 

      A large sized hole in the ozone layer

    • B. 

      Thinning of the ozone layer

    • C. 

      Small holes scattered in the ozone layer

    • D. 

      Thickening of the layer

  • 8. 
    Aquatic organisms are used to a certain range of temperature in the water bodies where they live. A sudden marked change in this temperature can affect:
    • A. 

      Breeding of animals

    • B. 

      More growth of the aquatic plants

    • C. 

      Process of digestion in animals

    • D. 

      Availability of nutrients

  • 9. 
    The presence of the fertilizers and sewage in polluted water provides a lot of nitrogen, causing excessive growth of algae which subsequently reduces the amount of dissolved oxygen in the water. Can you name this process of reduction of dissolved oxygen due to the excess growth of algae?
    • A. 

      Biomagnifications

    • B. 

      Eutrophication

    • C. 

      Algal bloom

      Decopmposition

  • 10. 
    A cool breeze after a hot day brings all of us considerable relief. This breeze is actually the moving air. What is the basic process that causes this movement of air?
    • A. 

      Pressure difference between the air of two regions

    • B. 

      Moving leaves of the plants

    • C. 

      Temperature difference between the two regions

    • D. 

      Striking of air with the mountains

  • 11.
