The Great Indian Plains are primarily formed by which river system?​

Correct option is C

The correct answer is (c) Indus-Ganga-Brahmaputra

Explanation:

The Great Indian Plains are formed by the alluvial deposits of the Indus, Ganga, and Brahmaputra river systems. These plains extend from Punjab in the west to Assam in the east and are among the most fertile and densely populated regions in the world. The deposition of sediments over thousands of years has created this vast flatland ideal for agriculture.

Information Booster:

• These plains cover parts of Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal, and Assam.

• The region is one of the largest alluvial plains globally.

• The plains are divided into subregions like the Punjab Plains, Ganga Plains, and Brahmaputra Plains.

• The alluvium is deposited by the rivers and their tributaries annually.

• The region supports major crops like wheat, rice, sugarcane, etc.

• The flat terrain and fertile soil make it ideal for irrigation and dense human settlement.

• Major cities like Delhi, Kolkata, Patna, and Lucknow lie in these plains.

Additional Information:

• Krishna-Godavari – These rivers form deltas in the eastern coastal plains of peninsular India.

• Kaveri-Periyar – Rivers located in the southern part of India, not related to the northern plains.

• Mahanadi-Narmada-Tapi – These rivers flow through central and eastern India; Narmada and Tapi form rift valleys, not alluvial plains.
