The Aravalli range, one of the world's oldest fold mountains, is a critical ecological and geographical feature in India, particularly for Rajasthan and Haryana. Standing over 400 meters above sea level, it acts as a natural barrier against desertification, recharges groundwater, and supports rich biodiversity. However, the range faces significant threats from illegal mining, encroachment, and deforestation, leading to environmental degradation.
The Supreme Court and National Green Tribunal have repeatedly intervened to protect the Aravallis, highlighting its importance for the region's ecological balance and water security. This issue is crucial for understanding environmental governance and sustainable development challenges in India.

पृष्ठभूमि
The Aravalli range is one of the world's oldest fold mountain systems, dating back to the Precambrian era. It stretches approximately 692 km across Gujarat, Rajasthan, Haryana, and Delhi. Geologically, it's a relict of a much larger ancient mountain system.
Ecologically, it plays a vital role as a natural barrier against the eastward spread of the Thar Desert, recharges groundwater, and supports unique biodiversity, including several endemic species. Its forests are crucial for local climate regulation and providing livelihoods.

उत्तर देखें
सही उत्तर: C
Options A, B, and D are direct ecological services provided by the Aravallis, as highlighted in the news summary and general ecological understanding. However, due to significant degradation, fragmentation, illegal mining, and encroachment, the Aravalli Range no longer provides a continuous, unbroken wildlife corridor across its entire length. While it still supports wildlife, the corridor function is severely compromised.
