Formed during the Precambrian eraover 2 billion years ago, the Aravallis represent a relict of an ancient mountain system. Geologically, it is one of the oldest mountain ranges on Earth. Historically, it has influenced regional climate, hydrology, and human settlements, acting as a natural barrier and resource provider for millennia.

Key Points

9 points
  • 1.

    Extends for about 692 km from Gujarat to Delhi, passing through Rajasthan and Haryana.

  • 2.

    Acts as a green lung for the NCR, helping to mitigate air pollution and regulate local climate.

  • 3.

    Crucial groundwater recharge zone for the arid and semi-arid regions of Rajasthan and Haryana, feeding numerous aquifers.

  • 4.

    Forms a biodiversity corridor, supporting diverse flora and fauna, including endemic species and migratory birds.

  • 5.

    Serves as a natural barrier against the eastward spread of the Thar Desert, preventing desertification in fertile plains.

  • 6.

    Source of various rivers like Banas, Luni, Sabarmati, and numerous seasonal streams.

  • 7.

    Rich in mineral resources (e.g., marble, granite, zinc, copper), leading to significant mining activities, often unregulated.

  • 8.

    The current news highlights that 31.8% of Aravalli hills in Gurugram, Faridabad, Nuh, and Rewari districts are unprotected due to a narrow definition of 'forest'.

  • 9.

    Home to several protected areas, wildlife sanctuaries, and national parks (e.g., Sariska Tiger Reserve, Mount Abu Wildlife Sanctuary).
