Explanations:The Aravalli Range is a significant geographical feature in the state of Rajasthan, India. It is one of the oldest fold mountain ranges in the world, formed approximately 1.8 billion years ago during the Proterozoic era. The Aravalli Range extends from the northwest to the southeast, spanning a distance of about 800 kilometers (497 miles) and covering parts of Rajasthan and Gujarat.
The Aravalli Range plays a crucial role in the geography and climate of Rajasthan. It acts as a natural barrier, influencing the distribution of rainfall and temperature across the state. The range is composed of a variety of rock types, including granite, gneiss, and schist, which have been subjected to extensive folding and faulting over millions of years.
Geographically, the Aravalli Range divides Rajasthan into two distinct regions: the fertile and well-watered region to the east and the arid and semi-arid region to the west. The eastern part of Rajasthan, which lies to the east of the Aravalli Range, receives more rainfall and has a more fertile soil, supporting agriculture and a denser population. In contrast, the western part of Rajasthan, which lies to the west of the Aravalli Range, is more arid and receives less rainfall, leading to a more sparse population and a landscape dominated by desert and semi-desert ecosystems.
Understanding the geographical features of Rajasthan, such as the Aravalli Range, is essential for comprehending the state's climate, ecology, and human settlement patterns. The Aravalli Range is not only a significant geographical feature but also a vital ecological and cultural resource for the region.
