65. In the context of which of the following do some scientists suggest the use of cirrus cloud thinning technique and the injection of sulphate aerosol into stratosphere?
(a) Creating the artificial rains in some regions
(b) Reducing the frequency and intensity of tropical cyclones
(c) Reducing the adverse effects of solar wind on the Earth
(d) Reducing the global warming
Answer: d
Explanation: Cirrus clouds do not reflect a lot of solar radiation back into space, but because they form at high altitudes and cold temperatures, they trap long-wave radiation and have a climate impact similar to greenhouse gases. Thus Thinning cirrus clouds would reduce the absorption of infrared radiation and proposed a form of climate engineering to reduce global warming. Another proposed Geo-engineering technique involves injecting reflective sulfate aerosol particles into Earth’s lower stratosphere to cast a small proportion of the inbound sunlight back into space and cool the planet off. Thus both are climate engineering/ Geoengineering techniques to reduce global warming.

81. Consider the following statements:
1. Agricultural soils release nitrogen oxides into the environment.
2. Cattle release ammonia into the environment.
3. Poultry industry releases reactive nitrogen compounds into the environment.
Which of the statements given above is/are correct?
(a) 1 and 3 only
(b) 2 and 3 only
(c) 2 only
(d) 1, 2 and 3
Answer: d
Explanation: Due to presence of Nitrogenous fertilizers, oxides of Nitrogen are released in atmosphere. Cattles/Ruminants Ruminant animals do not efficiently utilize dietary nitrogen. Excess nitrogen fed in the form of feed proteins is excreted in manure (urine + feces). Dairy cows on average secrete in milk 25 to 35 percent of the nitrogen they consume and almost all the remaining nitrogen is excreted in urine and feces with about half of the nitrogen excreted in urine.
Approximately 60 to 80 percent of the nitrogen in urine is in the form of urea. Nitrogen in manure can be converted to ammonia through bacterial degradation, primarily the conversion of urinary urea to ammonia. Urease, an enzyme produced by microorganisms in feces, reacts with urinary urea to form ammonia. Urease activity in feces is high and rapidly converts urea to ammonia after excretion. In poultry industry microorganisms releases Nitrogen from organic matter (fecal matter) in the atmosphere.

3. Hydrogen up to one-fifth by volume can be blended with CNG as fuel for buses.
4. H-CNG makes the fuel less expensive than CNG.
Which of the statements given above is / are correct?
(a) 1 only
(b) 2 and 3 only
(c) 4 only
(d) 1, 2, 3 and 4
Answer: b
Explanation: Statement 1 is incorrect: H-CNG reduces the emission of Carbon Monoxide up to 70%.
Statement 2 is correct: H-CNG as a fuel reduces the emission of carbon-di-oxide and hydrocarbon as compared to other fuels. Compared with natural gas, HCNG has many advantages when it comes to performance. However, due to the increased temperature and combustion duration that accompanies the hydrogen addition, an increase in NOx emissions is observed.
Statement 3 is correct: CNG as a fuel can be used in place of gasoline, diesel fuel and propane (C3H8) / LPG and its combustion produces fewer undesirable gases than the other mentioned fuels. When 18-20% of hydrogen as a fuel is mixed into the CNG it becomes pollution free as it reduces the emission of carbon-monoxide up to 20%.
Statement 4 is incorrect: Current cost of H2 is more than the cost of Natural Gas. Therefore, HCNG’s cost is more than CNG. https://coimbatore.nic.in/tourist-place/aliyar-dam/
