6. In mega cities of India, the dominant source of air pollution is (A) transport sector (B) thermal power (C) municipal waste (D) commercial sector Answer A Traffic congestion is severe in India's cities and towns. Traffic congestion is caused for several reasons, some of which are: increase in number of vehicles per kilometer of available road, a lack of intra-city divided-lane highways and intra-city expressways networks, lack of inter-city expressways, traffic accidents and chaos due to poor enforcement of traffic laws. Complete lack of traffic sense in Indian public is the main reason for the chaos on the roads.
December 2011 1. Which of the following pollutants affects the respiratory tract in humans? (A) Carbon monoxide (B) Nitric oxide (C) Sulphur di-oxide (D) Aerosols Answer C NO2 tends to affect the lower respiratory tract, whereas S02 affects the eyes and upper respiratory tract more often. Both can produce respiratory effects even at low levels of exposure, asthmatics being particularly susceptible to bronchial effects. Chronic exposure to NO2 is associated with increased risk of respiratory infections in young children; with chronic SO2 exposure, there is increased respiratory symptoms and impaired lung function

3. Which of the following is not a renewable natural resource ? (A) Clean air (B) Fertile soil (C) Fresh water (D) Salt Answer D Salt, or sodium chloride, is a non-renewable resource. A resource is defined as renewable only if it is self-replenishing. While new salt is being formed by natural processes in the earth, the timescale for that formation is too vast for salt to be considered self-replenishing in terms of human use
5. S and P waves are associated with (A) floods (B) wind energy (C) earthquakes (D) tidal energy Answer C Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P andS waves are known as "body waves".
