The Northern Plains of India are primarily formed by the deposits of which type of soil?
Show answer & explanation
Correct answer: B
Explanation
Correct Answer:
Alluvial soil
Explanation:
The Northern Plains of India are primarily formed by the deposition of alluvial soil brought down by the three major Himalayan river systems—the Indus, the Ganga, and the Brahmaputra. This type of soil is extremely fertile, rich in potash, phosphoric acid, and lime, making the Northern Plains one of the most agriculturally productive regions in the world.
Key Points:
Alluvial soil is broadly classified into two categories based on its age: Khadar (new alluvial, which is more fertile and renewed frequently) and Bhangar (older alluvial, containing calcareous deposits known as kankar).
It covers a vast expanse of northern and eastern India, supporting a dense population dependent on agriculture.
In addition to the Northern Plains, alluvial soil is also found in the eastern coastal plains, particularly in the deltas of the Mahanadi, the Godavari, the Krishna, and the Kaveri rivers.
