A glacial lake outflow refers to the water that drains from a lake formed by the melting of a glacier. These lakes, known as glacial lakes, can be found in regions with current or past glacial activity. The outflow typically occurs when the water level in the lake rises high enough to breach a natural dam, which could be made of ice, moraine (rock and sediment deposited by the glacier), or bedrock.

The outflow can happen gradually or suddenly, depending on the stability of the dam and the volume of water. Sudden outflows, known as glacial lake outburst floods (GLOFs), can be particularly dangerous. GLOFs occur when the natural dam fails catastrophically, releasing a large volume of water in a short period. This can lead to significant flooding downstream, potentially causing damage to infrastructure, ecosystems, and human settlements.

Glacial lake outflows are an important aspect of the hydrological cycle in glaciated regions and can have significant impacts on local and regional water systems, sediment transport, and landscape evolution.

2 .Piezoelectrics: (General Studies-III (250 marks)Technology, Economic Development, Biodiversity, Environment, Security, and Disaster Management)

refer to materials that can generate an electric charge in response to applied mechanical stress. This phenomenon is known as the piezoelectric effect. Conversely, these materials can also deform or change shape when an electric field is applied, which is called the inverse piezoelectric effect.

The term "piezoelectric" comes from the Greek word "piezein," meaning to press or squeeze.

Key Concepts:

1. Piezoelectric Effect: When a piezoelectric material is subjected to mechanical stress (such as pressure, vibration, or bending), it generates an electrical charge. This is used in various applications like sensors, actuators, and energy harvesting devices.

2. Inverse Piezoelectric Effect: When an electric field is applied to a piezoelectric material, it undergoes a mechanical deformation. This is utilized in devices like precision actuators, speakers, and ultrasonic transducers.

Common Piezoelectric Materials:

• Natural Crystals: Quartz, Rochelle salt, and tourmaline.

• Ceramics: Lead zirconate titanate (PZT), barium titanate.

• Polymers: Polyvinylidene fluoride (PVDF).

Applications:

1. Sensors and Transducers: Piezoelectric materials are used in microphones, accelerometers, and pressure sensors.

2. Actuators: They are employed in precision positioning devices, such as in inkjet printers and scanning probe microscopes.

3. Energy Harvesting: Piezoelectric materials can convert mechanical energy from vibrations or movements into electrical energy, useful in powering small electronic devices.

4. Medical Imaging: Ultrasonic transducers in medical imaging devices use piezoelectric materials to generate and receive sound waves.

5. Consumer Electronics: Piezoelectric elements are found in buzzers, speakers, and touchscreens.

Advantages:

• High sensitivity to mechanical stress.

• Ability to operate over a wide range of frequencies.

• Compact and lightweight.

Challenges:

• Brittleness in ceramic materials.

• Sensitivity to temperature changes.

• Degradation over time under high mechanical stress.

Piezoelectrics play a crucial role in modern technology, enabling the development of devices that require precise control and efficient energy conversion.

3 .On LGBTQIA+ rights, why India lags behind its Asian neighbours like Thailand:

 (GS Paper II: Governance, Constitution, Polity, Social Justice and International Relations)

key factors:

• Social and Cultural Conservatism: India is a deeply religious and conservative society, with strong traditional values that often clash with LGBTQIA+ rights. Homosexuality has historically been stigmatized and criminalized, leading to widespread discrimination and prejudice.   

  
  

• Political Influence of Religious Groups: Religious groups in India hold significant political influence and often oppose LGBTQIA+ rights based on religious doctrines. This opposition can hinder legislative progress and create a hostile environment for LGBTQIA+ individuals.   

  
  

• Lack of Legal Recognition: While India decriminalized homosexuality in 2018, same-sex marriage remains illegal. This lack of legal recognition denies LGBTQIA+ couples basic rights and protections enjoyed by heterosexual couples.   

  
  

• Limited Public Awareness and Education: There is a lack of public awareness and education regarding LGBTQIA+ issues in India. This can perpetuate stereotypes and misconceptions, hindering acceptance and understanding.   

  
  

• Slow Pace of Legal Reforms: Despite growing social acceptance, legal reforms in India often proceed at a slow pace. This can be attributed to bureaucratic hurdles, political resistance, and a lack of political will to address LGBTQIA+ rights.

It's important to note that this is a complex issue with no easy answers. While India lags behind some of its neighbors, it's also important to acknowledge the progress that has been made in recent years.

The decriminalization of homosexuality was a significant step forward, and there is a growing LGBTQIA+ rights movement in India advocating for further legal reforms and social change.   

4 .India's Petroleum Industry: India’s petroleum industry, a cornerstone of the nation’s energy security, encompasses exploration, production, refining, and distribution of petroleum products. With 23 refineries (19 PSUs, 3 private, and 1 joint venture), India’s refining capacity has grown from 215.066 MMTPA in 2014 to 256.816 MMTPA in 2024.

The sector, which began with the first oil well in Digboi, Assam (1867), has evolved significantly, driven by technological advancements and policy reforms like the National Exploration Licensing Policy (NELP). India ranks among the top five refining nations globally, with key exports to South Asia, Africa, and Europe.

The industry contributes significantly to GDP, employment, and socio-economic development.

Recent initiatives include the Oilfields Amendment Bill 2024, simplifying approvals, and promoting green energy through schemes like SATAT (Compressed Biogas), Ethanol Blending Program (targeting 20% blending by 2025-26), and Mission Green Hydrogen (5 MMTPA by 2030).

The sector is also expanding exploration acreage to 1 million sq. km by 2030 and increasing refining capacity to 309.5 MMTPA by 2030. India’s petroleum industry is poised for sustainable growth, aligning with global energy transitions and climate commitments.

Key Highlights:

• Refining Capacity: 256.816 MMTPA (2024), targeting 309.5 MMTPA by 2030.

• Ethanol Blending: 20% target by 2025-26.

• Green Hydrogen: 5 MMTPA target by 2030.

• Exploration Acreage: 1 million sq. km by 2030.

• Global Rankings: 4th in refining capacity, 7th in refined product exports, 2nd in ethanol blending.

Government Initiatives:

• Pradhan Mantri JI-VAN Yojana: Supports bio-ethanol projects.

• Strategic Petroleum Reserves: 5.33 MMT capacity.

• City Gas Distribution: Covers 733 districts, 100% mainland area.

Future Prospects: Focus on sustainability, green fuels, and energy security, with significant investments in exploration, refining, and renewable energy.
