    What do you call the rain that contains chemical waste and causes of damage to plants and animals?
    Solution

  • Question 2

    Solution

  • Question 3

  • Question 4
    1 / -0
    Which of the following is depleted by CFCs?
    Solution
    CFCs are the organic compounds containing carbon, fluorine and chlorine atoms. CFCs are involved in the greenhouse effect. It is particularly harmful because of its destructive reactions with ozone particles, which is responsible to protect the earth from UV radiations.
    Hence have a role in the depletion of the ozone layer.
    Thus the correct answer is option B. 
  • Question 5
    1 / -0
    Water pollution due to tailing from ore washing and inert suspended solids, known as _______.
  • Question 6

  • Question 7
    1 / -0
    What causes dust production?
  • Question 8
    1 / -0
    Free radicals of bromine are more destructive than _______ in case of ozone depletion.
    Solution
    • Free radicals are molecules with unpaired valency electrons, they are uncharged molecules so they are highly reactive.
    • The presence of free radicles in the atmosphere leads to depletion of the ozone layer (it act as a shield for the earth as it traps UV radiations which are harmful to organisms as they can damage skin cells, mutate DNA, and can even cause skin cancer). 
    • Refrigerants such as CFCs, and halons dissociate and produce free radical forms of bromine and chlorine in the earth's stratosphere. 
    • A single chlorine atom can destroy thousands of ozone molecules but bromine is about 50 times more efficient than chlorine at destroying stratospheric ozone. 

    So, the correct answer is option B.
  • Question 9
    1 / -0
