The term 'White Coal' is often used to describe?
Correct Answer: A. Hydroelectricity
Hydroelectricity is called white coal because it provides power like coal but is clean and renewable. It does not involve mining or air pollution. It is highly efficient for meeting peak load demands.
Which fossil fuel is often found trapped in sedimentary rock layers?
Correct Answer: C. Petroleum
Petroleum and natural gas are found in sedimentary basins where organic matter was buried under high pressure. They are often trapped in anticlines and fault traps. Geologists study rock formations to locate these valuable deposits.
What is the main drawback of Solar and Wind energy?
Correct Answer: D. Intermittency
Intermittency means these sources are not available 24/7 as the sun doesn't shine at night and wind doesn't always blow. This requires expensive battery storage or backup from other power sources. However, technology is rapidly improving to solve this issue.
Neyveli Lignite Corporation (NLC) is located in which state?
Correct Answer: D. Tamil Nadu
NLC is a Navratna company headquartered in Tamil Nadu. It operates large open-cast lignite mines and several thermal power plants. It significantly contributes to the energy requirements of the Southern states.
Nuclear power is generated by the process of?
Correct Answer: C. Nuclear fission
Current nuclear reactors produce energy by splitting the nuclei of heavy atoms like Uranium or Plutonium. This 'fission' releases a massive amount of heat energy. This heat is then used to generate electricity similar to thermal plants.
Which Indian state was the first to develop a solar policy?
Correct Answer: C. Gujarat
Gujarat pioneered the solar movement in India by launching its solar policy in 2009. This led to the development of Asia's first multi-megawatt solar park at Charanka. Since then, many other states have followed with similar initiatives.
Coal is classified into four types based on its moisture and ________ content.?
Correct Answer: D. Carbon
The carbon content determines the heating value and quality of the coal. Peat has the lowest carbon, while Anthracite has the highest. Bituminous coal is the most widely used variety for industrial purposes.
Which fuel is primarily used in aircraft engines?
Correct Answer: B. Kerosene (Aviation Turbine Fuel)
Aviation Turbine Fuel (ATF) is a specialized type of kerosene used to power jet engines. It must remain liquid at very low temperatures and have high energy density. It is highly refined to meet strict safety standards.
Raniganj, the first coal mine in India, is located in?
Correct Answer: B. West Bengal
Coal mining in India began in 1774 at Raniganj in West Bengal. It is one of the oldest and largest coalfields in the country. It remains an important source of coal for the Eastern region's industries.
Which state has the highest installed capacity of solar power in India?
Correct Answer: A. Rajasthan
Rajasthan leads India in solar power installed capacity due to its vast stretches of arid land, high solar irradiation levels, and favourable government policies. The Bhadla Solar Park in Rajasthan is one of the largest solar parks in the world. The state has consistently ranked first in solar energy generation, followed by Gujarat and Karnataka. India's solar energy programme has seen rapid expansion under the National Solar Mission.
