Read the passage and answer the questions. Mining is a hazardous occupation. The dust and noxious fumes inhaled by miners make them vulnerable to pulmonary diseases. The risk of collapsing mine roofs, inundation and fires in coalmines are a constant threat to miners. The water sources in the region get contaminated due to mining, and dumping of waste and slurry leads to degradation of land and soil. (i) Why is mining called a 'killer industry'? (ii) How does mining affect the environment? (iii) Suggest two measures to protect miners' health. (5 marks)

Read the passage and answer the questions. Petroleum is the next major energy source in India after coal. It provides fuel for heat and lighting, lubricants for machinery and raw materials for a number of manufacturing industries. Petroleum refineries act as a nodal industry for synthetic textile, fertiliser and numerous chemical industries. Most of the petroleum occurrences in India are associated with anticlines and fault traps in rock formations of the tertiary age. (i) Name the region that produces the most petroleum in India. (ii) What is meant by a nodal industry? (iii) Name the oldest oil-producing state in India. (5 marks)

Read the passage and answer the questions. India is blessed with plenty of sunlight. Photovoltaic technology converts sunlight directly into electricity. Solar energy is fast becoming popular in rural and remote areas. Some big solar power plants are being established in different parts of India, which will minimise the dependence of rural households on firewood and dung cakes. (i) What is photovoltaic technology? (ii) Why is solar energy becoming popular in rural areas? (iii) How will solar energy help conserve the environment? (5 marks)

Read the passage and answer the questions. Natural gas is an important clean energy resource found in association with or without petroleum. It is used as a source of energy as well as an industrial raw material in the petrochemical industry. Large reserves have been discovered in the Krishna-Godavari basin. The use of Compressed Natural Gas (CNG) for vehicles is gaining popularity. (i) Why is natural gas considered an environment-friendly fuel?
