The new alluvial deposits found in the Gangetic plain are known as _____.

Correct option is B

The correct answer is (b) Khadar

Khadar refers to the new (younger) alluvial deposits found in the floodplains of rivers like the Ganga. They are more fertile compared to the older alluvial deposits due to regular silt deposition during floods.

Bhabar:

• It is the region south of the Lower Himalayas and the Shivalik Hills.
• It is the alluvial apron of sediments washed down from the Shivalik along the northern edge of the Indo-Gangetic plain.
• It lies along the foot of the Shivaliks from the Indus to the Tista. It is 8 to 16 km wide.
• It comprises pebble-studded rocks in the shape of porous beds.
• The porosity is very high and hence small rivers disappear. Due to the porosity of the rocks, the streams disappear and flow underground.
• This region is not very suitable for agriculture.

Additional Information:

Bhangar:

• It is generally well-drained but contains concretion (kankars) of impure calcium carbonate.
• It represents a system of older alluvium, deposited away from the flood plains.
• The soil texture varies from loamy soil to clay loam.

Tarai:

• The Tarai region is a lowland area dispersed with marshes, thick forests, and swamps.
• These regions are rich in clay and tall grasslands.
• It runs parallel to the Bhabar tract.
