Aravali Mountain Range

Aravali Mountain Range क्या है?

The Aravali Mountain Range is one of the oldest fold mountain ranges in the world, stretching across four states (Gujarat, Rajasthan, Haryana) and the Union Territory of Delhi in western India. It plays a crucial role in the ecology and climate of the region, acting as a natural barrier to the spread of the Thar Desert and a vital watershed.

ऐतिहासिक पृष्ठभूमि

Geologically, the Aravalis are among the oldest geological structures on Earth, formed during the Proterozoic Eon. Historically, they have been significant for human settlements, biodiversity, and as a source of minerals. Their ecological importance has been recognized increasingly in recent decades due to environmental degradation.
