The newer, younger deposits of the flood plain in North-Indian plain, are known as

Question

Accepted Answer

The newer, younger deposits of the flood plain in the North-Indian plain are known as "Khadar." Let's explore why Option 2 is the correct answer and why the other options are incorrect.

1. **Explanation for Option 2 (Khadar):**
   - Khadar refers to the newer alluvial deposits found in the floodplains of rivers in the North-Indian plain. These deposits are formed by the annual flooding of rivers, which brings fresh silt and sediments. As a result, Khadar soils are very fertile and are replenished regularly, making them ideal for agriculture. The continuous deposition of new sediments ensures that the soil remains rich in nutrients, supporting the growth of crops like wheat, rice, and sugarcane.

2. **Explanation for why other options are incorrect:**

- **Option 1 (Bhanger):**
     - Bhanger refers to the older alluvial deposits found in the North-Indian plain. These deposits are higher in elevation compared to Khadar and are not subject to regular flooding. As a result, Bhanger soils are less fertile than Khadar soils because they do not receive the regular replenishment of nutrients from floodwaters. Bhanger areas are often characterized by the presence of calcareous nodules known as "kankar."

- **Option 3 (Bhabar):**
     - Bhabar is a narrow belt of coarse gravel and pebbles found at the foothills of the Himalayas, just above the Terai region. It is not a floodplain deposit but rather a zone where rivers descending from the mountains deposit their load of coarse materials. The Bhabar region is characterized by porous soil, which allows water to quickly percolate down, making it unsuitable for agriculture.

- **Option 4 (Terai):**
     - Terai is a marshy and swampy region located south of the Bhabar belt. It is characterized by a high water table and is often waterlogged. The Terai region is not associated with the newer alluvial deposits of the floodplain but rather with the accumulation of fine sediments and organic matter in a water-saturated environment. While it is fertile, it is distinct from the Khadar floodplain deposits.

In conclusion, Option 2 (Khadar) is the correct answer because it accurately describes the newer, younger deposits of the floodplain in the North-Indian plain, which are regularly replenished by river floods and are highly fertile. The other options describe different types of geological formations or soil types that do not match the characteristics of Khadar.
