45. Which of the following is a vehicle that doesn’t emit tailpipe pollutants from the onboard source of power?
[A] BS VI vehicles
[B] Electric Vehicles
[C] ZEV vehicles
[D] Power vehicles
Show Answer
Correct Answer: C [ZEV vehicles]
Notes:
Zero emission vehicles which are also called as ZEV’s are those vehicles that do not emit any tailpipe pollutants such as carbon monoxide, carbon dioxide from the onboard source of power.
46. Which of the following green house gases has the greatest heattrapping ability?
[A] Carbon dioxide
[B] Chlorofluoro carbon
[C] Nitrous oxide
[D] Methane
Show Answer
Correct Answer: B [Chlorofluoro carbon]
Notes:
Gases that trap heat in the atmosphere are called green house gases. Global Warming Potentials (GWPs) are used to compare the abilities of different green house gases to trap heat in the atmosphere. Carbon dioxide is used as the base for all the calculations, so its global warming potential is 1.2. The higher the GWP, the more heat the specific gas can keep in the atmosphere. Fluorinated gases : Chlorofluorocarbons, Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride : are synthetic, powerful greenhouse gases that have highest heat trapping abilities. These gases are 1,000; 10,000 even 20,000 times more powerful than Carbon dioxide (CO2) at trapping heat and many can stay in our atmosphere for thousands of years.
47. Which of the following statement is incorrect?
[A] Forest protect the soil from erosion
[B] Plants and animals in a forest are not dependent on one another
[C] Forests influence the climate and water cycle
[D] Soil helps forest to grow and regenerate
Show Answer
Correct Answer: B [Plants and animals in a forest are not dependent on one another]
Notes:
Plants and animals interact with each other in the environment. In the food chain, some animals each other animals and use them for food. Some animals depend on others through symbiotic relationships. Plants provide a global benefit to animals by releasing oxygen into the atmosphere.
48. What was the main aim of Basel Convention?
[A] Bio-diversity Conservation
[B] Global Warming
[C] Protection of Ozone layer
[D] Climate Change
Show Answer
Correct Answer: A [Bio-diversity Conservation]
Notes:
Basel Convention is an international treaty that was designed to reduce the movements of hazardous waste between nations, and specifically to prevent transfer of hazardous waste from developed to less developed countries (LDCs). It ultimately aims at biodiversity conservation.
49. Which of the following is not a particulate pollutant?
[A] Ozone
[B] Smoke
[C] Dust
[D] Soot
Show Answer
Correct Answer: A [Ozone]
Notes:
Particulate matter (PM) is a complex mixture of extremely small particles and liquid droplets that get into the air. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. Ozone is created in the atmosphere when the sun’s rays split oxygen molecules into single atoms. These atoms combine with nearby oxygen to form a three-oxygen molecule, called ozone.
50. Montreal Protocol is related to which of the following?
[A] Ozone layer
[B] E-waste
[C] Water pollution
[D] None of the above
Show Answer
Correct Answer: A [Ozone layer]
Notes:
The Montreal Protocol on Substances that Deplete the Ozone Layer was designed to reduce the production and consumption of ozone depleting substances in order to reduce their abundance in the atmosphere, and thereby protect the earth’s fragile ozone Layer. The original Montreal Protocol was agreed on 16 September 1987 and entered into force on 1 January 1989. In 1995, the United Nations named September 16 the International Day for the Protection of the Ozone Layer, also known as World Ozone Day.
