INDIAN GEOGRAPHY

Detailed explanation-1: -The newer and younger deposits of the floodplains are called Khadar. This region has the new alluvial soil which gets renewed almost every year and so are fertile. It is ideal for intensive agriculture.

Detailed explanation-2: -Bangar is a less fertile soil and it is an old alluvial soil. Bangar areas are less prone to flooding but are usually more sandy and less fertile as well. They consist of a higher concentration of kankar nodules. They are slightly elevated terraces. That’s why these areas are less fertile.

Detailed explanation-3: -The Bhangar region has calcareous deposits, locally known as Kankar; the Khadar soil has fine silt and clay. The soil in Bhangar is also coarser.

Detailed explanation-4: -Alluvium is loose, unconsolidated soil or sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel.

Detailed explanation-5: -These water bodies are locally known as beels (Assam, West Bengal, Arunachal Pradesh, Meghalaya and Tripura), maun, chaurs and dhars (Bihar), pats (Manipur), charhas and boars (northern and south eastern West Bengal respectively).
