  • Glacial Retreat: As the climate warms or the glacier melts, it slowly retreats. The sea level rises, filling the valley with seawater, creating a long, narrow inlet with steep cliffs on either side.

Why They Are Picturesque:

  • Scenic Beauty: Fjords are known for their breathtaking beauty, with deep blue waters contrasted against towering, lush green cliffs. The sharp contrast between land and water creates stunning scenery.
  • Biodiversity: Fjords often support rich ecosystems due to the mix of cold freshwater and seawater, attracting diverse marine life and providing excellent opportunities for wildlife viewing.
  • Recreation: Fjords offer opportunities for various recreational activities like hiking, kayaking, and sailing, making them popular destinations for outdoor enthusiasts.
  • Cultural Significance: Fjords are often associated with cultural heritage and history, adding cultural and historical depth to their picturesque appeal.

Fjords are formed through glacial processes and are celebrated for their natural beauty, biodiversity, recreational opportunities, and cultural significance, making them some of the most picturesque areas in the world.

 

Q7. Why is the South-West Monsoon called ‘Purvaiya’ (easterly) Bhojpur Region? How has this directional seasonal wind system influenced the cultural ethos of the region? (Answer in 150 words) 10

ANSWER:

The South-West Monsoon, known as ‘Purvaiya’ (easterly) in the Bhojpur region, is named so because of its predominant easterly direction when it arrives in the Indian subcontinent. This monsoon is characterized by moisture-laden winds blowing from the Indian Ocean towards the subcontinent, resulting in heavy rainfall.

The directional seasonal wind system, ‘Purvaiya,’ has deeply influenced the cultural ethos of the Bhojpur region in several ways:

  • Agriculture: ‘Purvaiya’ plays a crucial role in the region’s agriculture. The timely arrival of monsoon rains is eagerly awaited, as it brings life to the parched lands and sustains crops like rice, wheat, and pulses. The monsoon’s reliability has shaped the region’s agrarian calendar and rituals.
  • Festivals: The onset of the monsoon is celebrated with various festivals and rituals that reflect the cultural significance of rainfall. These traditions often involve dance, music, and communal gatherings, fostering a sense of community and identity.
  • Water Management: The monsoon’s unpredictability has led to the development of traditional water harvesting and management techniques, such as ‘talabs’ (ponds) and ‘ahars’ (reservoirs), which are integral to the region’s cultural heritage.
  • Language and Folklore: ‘Purvaiya’ and monsoon-related themes find their way into the region’s literature, songs, and folklore, highlighting the monsoon’s enduring presence in the cultural narrative.

In essence, the ‘Purvaiya’ monsoon not only sustains life in the Bhojpur region but also weaves its way into the region’s cultural fabric, influencing traditions, festivals, agriculture, and language, while fostering a sense of connection with the natural world.

 

Q8. Do you think marriage as a sacrament is losing its value in Modern India? (Answer in 150 words) 10

ANSWER:

The concept of marriage as a sacrament is experiencing notable changes in modern India. While it is not accurate to claim that it has completely lost its value, there are several factors contributing to its evolving nature:

  1. Changing Social Norms: Modern India has witnessed a shift in social norms and values, with greater emphasis on individualism and personal choices. This can lead to a more pragmatic view of marriage as a partnership, rather than a sacrament.
  2. Rise in Love Marriages: Love marriages, which often prioritize personal compatibility and affection over traditional rituals and sacramental aspects, have become more prevalent. This shift reflects changing attitudes towards marriage.
  3. Divorce Rates: The rising divorce rates suggest that some couples no longer see marriage as an indissoluble sacrament, but rather as a contract that can be terminated if the relationship deteriorates.
  4. Gender Roles: Changing gender roles and increasing gender equality have altered power dynamics within marriages, further impacting the traditional sacramental view.
  5. Cultural Diversity: India’s cultural diversity means that views on marriage can vary significantly across regions and communities, making it difficult to make a blanket statement about the entire country.

While the sacramental view of marriage still holds value for many in India, it is undeniably evolving in response to shifting social, cultural, and individual dynamics. Marriage is increasingly being seen as a blend of tradition and personal choice, reflecting the complex tapestry of modern Indian society.

 

Q9.  Explain why suicide among young women is increasing in Indian society. (Answer in 150 words ) 10
