Which of the following is a major long-term consequence of coal mining? Formation of fertile soil in mining areas Increase in groundwater levels Acid mine drainage leading to water pollution Natural restoration of forests in mining regions None 2. Which of the following industries is most dependent on petrochemicals? Textile industry Paper industry Wood industry Agriculture None 3. Which of the following is a major limitation of biofuels compared to fossil fuels? Biofuels cannot be produced on a large scale. Biofuels release more greenhouse gases than fossil fuels. Biofuels have a lower energy density than fossil fuels. Biofuels are non-renewable. None 4. Which statement correctly distinguishes renewable resources from non-renewable resources? Renewable resources cannot be replenished in a short time, while non-renewable resources can. Non-renewable resources are inexhaustible, whereas renewable resources are exhaustible. Renewable resources are naturally replenished over short periods, while non-renewable resources take millions of years to form. Non-renewable resources can be created through artificial means, while renewable resources cannot. None 5. Which factor is most essential for the formation of petroleum over millions of years? Exposure to the atmosphere High levels of sunlight High pressure and temperature Proximity to volcanic activity None 6. Which of the following methods is the most effective in reducing dependence on fossil fuels? Increasing fossil fuel extraction Investing in nuclear power plants Widespread adoption of energy-efficient technologies Encouraging the use of coal-fired power stations None 7. Which of the following contributes the least to an individual's carbon footprint? Driving a gasoline-powered car daily Using electricity generated from coal Growing a home vegetable garden Using plastic bags None 8. Which process is used in petroleum refineries to break down large hydrocarbons into smaller, more useful hydrocarbons? Hydrolysis Polymerization Cracking Hydrogenation None 9. Which of the following pollutants is released in large quantities when coal is burned? Sulfur dioxide Chlorine gas Methane Nitrogen gas None 10. If fossil fuels were to be exhausted, which of the following would be the most significant consequence for modern industries? Increase in agricultural productivity Loss of raw materials for chemical industries Abundance of renewable energy sources Elimination of greenhouse gas emissions None 11. Why is coal considered to be a less desirable source of energy compared to natural gas? Coal is more expensive than natural gas. Coal releases more pollutants and greenhouse gases than natural gas. Coal has a higher energy content than natural gas. Coal is renewable, while natural gas is non-renewable. None 12. Which fuel derived from petroleum is used in the largest quantity in modern transportation? Diesel Petrol Kerosene Lubricating oil None 13. What is the most likely future trend in energy resource development? Complete reliance on fossil fuels Decreasing investments in renewable energy Increasing use of renewable and clean energy sources Expanding coal mining to meet growing energy needs None 14. Which of the following by-products of coal processing is used to manufacture paints and dyes? Coke Coal tar Ammonia Synthetic gas None 15. Which of the following measures is most critical for ensuring future energy security? Relying solely on existing fossil fuel reserves Exploring and developing renewable energy technologies Increasing oil drilling in fragile ecosystems Eliminating nuclear energy as an option None 1 out of 15 Time's up
