Answers
Answer:
no.1/ alluvial soil is found in the northern plains and delta,-----its right answer
Answer:
Both assertion and reason are true but reason is not the correct explanation of the assertion.
Explanation:
Northern Plains is where alluvial soil is most prevalent. The Northern Plains and their valleys are covered in these soils. The Indo-Gangetic-Brahmaputra Rivers' silt deposition is the primary cause of the formation of these soils, which are deposition soils. This soil is spread out along the riverbanks when the river overflows.
Both of the middle hill valleys near Kathmandu and Pokhara as well as the Terai region's valleys have alluvial soil. The Siwalik and Mahabharat hills are separated by the valleys, which at certain points widen to form flat, fertile valleys known as Dun valleys. In the flood plain regions along the river courses, new alluvial soil with much more sand grains than clay has been deposited. Additionally, alluvial soil can be found higher up than the flood plain, which makes up the majority of the terrain.
In the middle and upper ganga plains, two main kinds of alluvial soils have evolved. Khadar and Bhangar are the types . Every year, floods deposit khadar, a new type of alluvium that improves the soil by adding fine silts. A system of old alluvium that was deposited far from flood plains is represented by Bhangar.
