Aravali Range

Aravali Range क्या है?

The Aravali Range is one of the oldest fold mountain ranges in the world, stretching across Rajasthan, Haryana, Gujarat, and Delhi. It is a critical ecological corridor, acting as a natural barrier against desertification from the Thar Desert and providing vital ecosystem services, including water recharge and biodiversity conservation.

ऐतिहासिक पृष्ठभूमि

Formed during the Precambrian era, making it one of the oldest geological features on Earth, dating back over 2.5 billion years. It has undergone significant erosion over millennia, resulting in its present-day relict form. Historically, it has been a region of rich biodiversity and cultural significance.
