Q2) What are the various hazards of mining? Mark 2
Answer 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. Dumping of waste and slurry leads to degradation of land, soil, and increase in stream and river pollution.
Case Study 3:
India’s energy landscape is largely reliant on conventional energy resources, which have been the backbone of the nation’s industrialization and economic growth. These resources primarily include coal, oil, and natural gas.
Coal has historically been India’s dominant energy source, fueling power plants and industries. However, concerns about environmental pollution and greenhouse gas emissions have prompted a shift towards cleaner alternatives. Oil and natural gas are vital for transportation and industrial processes. India is increasingly exploring offshore reserves and diversifying its sources to reduce dependency on imports.
While conventional energy resources remain essential, India is making significant strides in renewable energy, aiming to achieve a sustainable energy mix. In conclusion, India’s conventional energy resources continue to be pivotal for its development, but the nation is gradually embracing cleaner alternatives to meet the challenges of the 21st century. Balancing energy security, environmental sustainability, and economic growth is the key to a prosperous future.
Q1) Give an account of variety of coals found in India? Mark 2
Answer Coal is found in a variety of forms depending on the degrees of compression and the depth and time of burial.
Lignite is a low grade brown coal, which is soft with high moisture content.
Coal that has been buried deep and subjected to increased temperatures is bituminous coal. It is the most popular coal in commercial use.
Anthracite is the highest quality hard coal.
Q2) Give details of India natural gas pipeline infrastructure? Mark 2
Answer The first 1,700 km long Hazira-VijaipurJagdishpur (HVJ) cross country gas pipeline, constructed by GAIL (India), linked Mumbai High and Bassein gas fields. This artery provided impetus to Indian gas market development. Overall, India’s gas infrastructure has expanded over ten times from 1,700 km to 18,500 km of cross-country pipelines and is expected to soon reach over 34, 000 km as Gas Grid by linking all gas sources and consuming markets across the country including North Eastern states.
Case Study 4:
Non-conventional or renewable energy sources have assumed a paramount role in India’s quest for sustainable development and energy security. These sources, which include solar, wind, hydropower, biomass, and geothermal energy, have witnessed remarkable growth and adoption in recent years. Solar energy, in particular, has experienced a meteoric rise, with India emerging as one of the world’s largest solar power producers.
Wind energy is another significant contributor, with wind farms dotting the landscape in states like Tamil Nadu, Maharashtra, and Gujarat. Hydropower, biomass, and geothermal sources also play vital roles in India’s renewable energy portfolio. Non-conventional sources are helping India reduce its carbon footprint, combat climate change, and enhance energy self-sufficiency. They are bolstering rural electrification, creating jobs, and catalyzing economic growth while promoting a cleaner and greener future. In conclusion, non-conventional energy sources are pivotal in India’s transition towards a sustainable, diversified, and resilient energy sector. Their continued expansion and integration are essential for a brighter, more environmentally conscious future.
Q1) Give details of locations of fuels of nuclear reactor present in India? Mark 1
Answer Uranium and Thorium, which are available in Jharkhand and the Aravalli ranges of Rajasthan are used for generating atomic or nuclear power. The Monazite sands of Kerala is also rich in Thorium.
Q2) Biogas as a effective use of cow dung. Comment Mark 1
Answer Biogas plants provide twin benefits to the farmer in the form of energy and improved quality of manure. It improves the quality of manure and also prevents the loss of trees and manure due to burning of fuel wood and cow dung cakes.
Q3) How geothermal energy works? Mark 2
Answer The Earth grows progressively hotter with increasing depth. Where the geothermal gradient is high, high temperatures are found at shallow depths. Groundwater in such areas absorbs heat from the rocks and becomes hot. It is so hot that when it rises to the earth’s surface, it turns into steam. This steam is used to drive turbines and generate electricity.

The promotion of renewable energy sources, energy efficiency measures, and a shift towards cleaner technologies are pivotal for energy security and reducing our carbon footprint.
In conclusion, conserving minerals and energy resources is a national responsibility. It not only safeguards our environment but also ensures sustained economic growth, energy security, and a brighter future for India and its citizens.
Q1) Why conservation of minerals is important? Mark 2
Answer The total volume of workable mineral deposits is an insignificant fraction i.e. one per cent of the earth’s crust, rapidly consuming mineral resources that required millions of years to be created and concentrated. The geological processes of mineral formation are so slow that the rates of replenishment are infinitely small in comparison to the present rates of consumption. Mineral resources are, therefore, finite and non-renewable.
Q2) How as a citizen we can conserve energy ? Mark 2
Answer As concerned citizens we can do our bit by using public transport systems instead of individual vehicles; switching off electricity when not in use, using power-saving devices and using non-conventional sources of energy.
