Why can the agricultural value of Khadar in flood plains differ from Bhangar?

Answer and explanation

Correct answer: Khadar can be fresher and more fertile due to new deposits

Khadar and Bhangar are both types of alluvial deposits found in the northern plains, but they differ in age and position. Khadar is newer alluvium deposited by relatively recent floods, so it is often replenished with fresh silt and may be more fertile. Bhangar is older alluvium, usually found on higher terraces and less frequently renewed by floods. Therefore, option A correctly explains why their agricultural value can differ.

The key comparison is new alluvium versus old alluvium. Floodwaters periodically spread fine sediments over the low-lying flood plain, producing Khadar. These fresh deposits can restore nutrients and improve cultivation, although floods may also damage crops. Bhangar has existed longer and may contain older, less frequently renewed material, sometimes with concentrations such as kankar. The other options misidentify both landforms. Thus A is correct and the supplied explanation is accurate.
