Correct option is B
The correct answer is option (b) Southern part of Vindhya Mountain
Explanation
The Southern part of the Vindhya Mountain, along with the peninsular plateau, is considered the most ancient landmass in India. This region was formed as a part of the Gondwana landmass during the Precambrian period, making it older than other regions like the Gangetic valley or the North Western Indian Valley. The Peninsular Plateau includes some of the oldest rocks in the world, particularly those found in areas like Chhattisgarh, Madhya Pradesh, and Maharashtra, and is believed to be over 3 billion years old.
This region was part of the supercontinent Gondwana, which later broke apart, and the landmass that is now the peninsular plateau became a stable geological feature. Due to its geological age and historical stability, it is regarded as one of the oldest landforms in India.
Information Booster
The Peninsular Plateau is part of the oldest landmass in India.
Formed from the Gondwana land during the Precambrian period.
Includes the Southern Vindhya region and Deccan Plateau.
The landmass is over 3 billion years old.
Known for its stable geology and ancient rock formations.
Additional Knowledge
(a) Gangetic Valley:
The Gangetic Valley is an important region for the development of early civilizations, especially during the Indus Valley Civilization. However, it is relatively younger than the peninsular plateau in terms of geological history.
(b) Southern part of Vindhya Mountain:
Correct Answer. The Southern Vindhya region is part of the peninsular plateau, the most ancient landmass in India. It was formed by the breakup of Gondwana and is much older than the other regions of India.
(c) North Western Indian Valley:
The North Western Indian Valley is part of the Indo-Gangetic Plain, which is a relatively young region in terms of its geological history. It was formed by river and floodplain deposits, making it younger than the peninsular plateau.
(d) North Eastern part of India:
The North Eastern part of India is geographically significant but does not represent the most ancient landmass. Its topography and geology are diverse, but it does not predate the peninsular plateau.
