The Oldest Mountain System According to Geological History

The Aravalli mountain range in India is considered the oldest mountain system according to geological history. Here are some details to explain why:

Formation
The Aravalli range was formed around 3.5 billion years ago during the Precambrian era. It was formed by the collision of two land masses - the Indian Plate and the Eurasian Plate.

Erosion
Over the years, the Aravalli range has undergone a lot of erosion due to weathering and tectonic activity. This has resulted in the mountains being much lower in height than they originally were.

Geological Significance
The Aravalli range is not just the oldest mountain system, but it also has great geological significance. It is home to some of the oldest rocks in the world, including the Bhander limestone and the Delhi Supergroup. These rocks provide valuable insights into the geological history of the Earth.

Biodiversity
The Aravalli range is also home to a diverse range of flora and fauna. It is a crucial habitat for several threatened and endangered species like the Indian leopard, sloth bear, and Indian pangolin.

Human History
The Aravalli range has played an important role in Indian history. It has been a source of minerals like copper, lead, and zinc since ancient times. It was also a site of early human settlements like the Indus Valley Civilization.

Conclusion
In conclusion, the Aravalli mountain range is considered the oldest mountain system according to geological history. It has played an important role in shaping the geological, ecological, and human history of India.
