India possesses significant reserves of natural gas hydrates, particularly in regions such as the Krishna-Godavari, Cauvery, and Kerala basins, as well as the Andaman Sea and Konkan basin. These hydrates represent a potential energy resource that could contribute to meeting the country’s growing energy demands.

The potential benefits of exploiting natural gas hydrates in India include:

1. Sustainable Energy Resource: Gas hydrates could serve as a less-polluting and abundant energy source, complementing traditional hydrocarbons.
2. Carbon Dioxide Sequestration: Hydrates can form complexes with CO₂, aiding in its sequestration and helping mitigate climate change impacts.
3. Gas Storage and Transportation: Hydrates offer an efficient means for bulk gas storage and transportation, enhancing energy security.

However, several challenges impede the exploration and utilization of these resources:

• Geophysical Challenges: Extraction can weaken seabed stability, leading to slope failures. Pressure changes during production may also cause reservoir depletion.
• Environmental Challenges: Disturbing hydrate sediments can harm marine ecosystems and potentially release methane, a potent greenhouse gas, exacerbating climate change.
• Economic Challenges: High extraction and shipping costs, coupled with the need for substantial capital investment, raise concerns about commercial viability.
• Technological Challenges: Existing extraction technologies may not be compatible with India’s specific hydrate formations, necessitating advanced research and development.

To address these issues, the Indian government has initiated the National Gas Hydrate Programme (NGHP) to explore and develop gas hydrate resources. Collaborations with countries like the USA, Canada, and Japan aim to advance research and technological capabilities. Institutions such as IIT Madras, in partnership with GAIL, are also working on projects to recover methane from hydrates while sequestering CO₂.

In conclusion, while natural gas hydrates present a promising energy opportunity for India, realizing their potential requires overcoming significant geophysical, environmental, economic, and technological challenges through sustained research, investment, and international cooperation.

Indian philosophy encompasses diverse traditions that explore the nature of existence, knowledge, and liberation. These traditions are broadly categorized into orthodox (Āstika) and heterodox (Nāstika) schools, based on their acceptance of the Vedas’ authority.

Orthodox (Āstika) Schools:

1. Nyāya: Founded by sage Gotama, this school emphasizes logic and epistemology, focusing on the means of acquiring valid knowledge.
2. Vaiśeṣika: Attributed to sage Kaṇāda, it proposes an atomistic metaphysics, suggesting that the universe comprises indivisible atoms and categorizing reality into distinct categories.
3. Sāṃkhya: Ascribed to sage Kapila, it presents a dualistic framework distinguishing between consciousness (Puruṣa) and matter (Prakṛti), aiming for liberation through discerning their separation.
4. Yoga: Linked to sage Patañjali, this practical discipline complements Sāṃkhya metaphysics, advocating for mental and physical practices to achieve spiritual liberation.
5. Pūrva Mīmāṃsā: Founded by sage Jaimini, it focuses on ritualistic aspects of the Vedas, emphasizing the performance of duties as a means to attain desired outcomes.
6. Vedānta (Uttara Mīmāṃsā): Associated with sage Vyāsa, it explores the philosophical teachings of the Upanishads, particularly concerning the nature of Brahman (ultimate reality) and Ātman (soul), leading to various sub-schools like Advaita (non-dualism) and Dvaita (dualism).

Heterodox (Nāstika) Schools:

1. Buddhism: Founded by Siddhartha Gautama (the Buddha), it teaches the Four Noble Truths and the Eightfold Path as a means to end suffering and attain Nirvana.
2. Jainism: Established by Mahavira, it emphasizes non-violence (Ahimsa) and asceticism, advocating for liberation through self-discipline and purity.
3. Cārvāka: A materialistic and skeptical school that rejects the afterlife and advocates for direct perception as the sole means of knowledge.

These philosophical systems have profoundly influenced Indian thought, offering diverse perspectives on metaphysics, ethics, and the path to liberation.

The League of Nations, created after World War I, aimed to promote international peace and cooperation. However, its effectiveness was limited due to several factors:

1. Lack of Participation: The United States, despite playing a key role in its creation, never joined the League, weakening its authority.
2. Inability to Enforce Decisions: The League lacked a military force and relied on sanctions, which were often ineffective.
3. Failure in Key Conflicts: The League struggled to prevent aggression, as seen in the invasions of Manchuria (1931) and Ethiopia (1935), where it failed to take decisive action.
4. Limited Membership and Influence: Major powers, including Germany and the Soviet Union, were initially excluded or left, reducing the League’s global influence.

Ultimately, the League was unable to prevent the rise of fascism or the outbreak of World War II, signaling its failure to preserve long-term peace.

Global atmospheric circulation refers to the movement of air in large-scale patterns across the globe, driven by the Sun’s energy. It involves three main cells in each hemisphere: the Hadley, Ferrell, and Polar cells.

• Hadley Cell: Air rises near the equator, cools, and descends at 30° latitude, creating tropical climates.
• Ferrell Cell: Moves air towards the poles, where it converges with cold air, creating temperate zones.
• Polar Cell: Cold air sinks at the poles, moving towards the equator.

These air patterns regulate global weather and climate, including jet streams and prevailing winds, which impact regional climates such as deserts and temperate zones​.

Definition of Ferrous Minerals

Ferrous minerals are those that contain iron as their primary component. They are metallic minerals known for their magnetic properties and utility in producing iron and steel. Examples include iron ore, manganese, and chromite.

Distribution of Iron Ore in India

India has abundant iron ore reserves, making it a leading producer globally. The major iron ore-producing states are:

• Odisha: The largest producer, contributing over 50% of India’s total production. Major mines include Barbil, Keonjhar, and Mayurbhanj districts, with high-grade hematite reserves.
• Chhattisgarh: Known for the Bailadila range in the Dantewada district, which produces high-quality iron ore suitable for export.
• Karnataka: Key mines include the Bellary, Chitradurga, and Tumkur districts. The Kudremukh mines are known for their magnetite reserves.
• Jharkhand: Significant reserves in the Singhbhum district, especially in the Noamundi and Gua mines.
• Maharashtra and Goa: Small-scale mining occurs, with Goa exporting low-grade iron ore.

Trends

• Increased production due to rising demand in domestic and international markets.
• A shift toward sustainable mining practices.
• Policies like National Steel Policy 2017 aim to enhance iron ore production to meet steel industry demands.
