    Planting of trees on barren land is called 
    Solution
    • Afforestation is the process of establishment of a forest or stands of trees in areas where there no forest exists. 
    • It not only creates forests but also increases the carbon capture and sequestration besides improving biodiversity. 
    • Understanding the role of trees as a critical part of the urban infrastructure, most governments are trying to increase forest areas close to human settlements. 
    • Such afforestation initiatives are part of the social forestry programs. The afforestation efforts will in general increase rainfall
    So, the correct answer is 'Afforestation'
  • Question 3
    1 / -0
    If the smog density of an area increases, it indicates
    Solution
    Pollution Under Control (PUC) Certificate is a certificate that is mandatory for every vehicle owner to carry. The certification indicates that the emissions from the vehicle meet the standard pollution norms and do not pollute the environment by determining whether the vehicle contributes to air pollution which can be determined by smog density. Thus the correct answer is option C.
  • Question 4

  • Question 5
    1 / -0
    ............ is a man-made source of air pollution.
    Solution
    Farming is considered as the major source of air pollution due to man. This is the man-made source of air pollution which allows the particles to enter the atmosphere. The movement of tractors will cause the soil particles to rise up in the air. The particles from the fertilizers and pesticides spray enter the atmosphere. Also during harvesting and husking, the small particles in the form of pollens and husks can result in air pollution. 
    Thus, the correct answer is option B. 
  • Question 6
    1 / -0
    If deforestation is done in large scale, this natural calamity may occur
    Solution
    If deforestation is performed, there will be no trees so, the amount of the greenhouse gasses will increase in the atmosphere. These greenhouse gasses trap heat from the infrared radiation in the atmosphere and increases the atmosphere's temperature i.e, global warming. 
    Thus, the correct answer is option C. 
  • Question 7
    1 / -0
    Of the following, which is a greenhouse gas?
    Solution
    Greenhouse gases generally traps the radiations of the earth which leads to increase in the temperature of the earth and is the major cause for global warming. The greenhouse gases includes water vapour, carbon dioxide, methane, nitrous oxide, and ozone.
    Thus, the correct answer is option C.
  • Question 8
    1 / -0
    Which one of the following diseases is caused due to ozone depletion on human?
    Solution
    • Due to the ozone depletion, the UV rays are filtered in the Earth's atmosphere. 
    • This ray results in the development of various diseases. One of the common disorder is erythema. 
    • This is a disease in which there are reddening and swelling of the skin. There is swelling of the mucous membranes. 
    • There is an increase in the blood flow from the peripheral capillaries which results in inflammation.
    • Thus, the correct answer is option D. 
  • Question 9
    1 / -0
    Which  one of the following is not a reason for shortage of usable water?
    Solution
    Overuse of the water resources will result in the exhaustion of the water supply. The climatic change has resulted in global warming and seasonal variations. There is a decrease in the annual rainfall which was received by a region due to shortening of the seasons. Deforestation has resulted in a decrease in the number of trees which thereby affect the amount of rainfall which was received. There is soil erosion which results in water run off.The decrease in the level of the sea is not a reason for the shortage of usable water. 
    Thus, the correct answer is option D. 
  • Question 10
    1 / -0
    The pollutant responsible for ozone depletion is _______.
    Solution
    CFCs like ferons used in refrigerators are the main cause of ozone depletion. Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules.
    So, the correct answer is option A.
