The soil that is present over the piedmont plains such as Chos and Duars is
Piedmont Plains Soil Type Explained
The question asks to identify the soil type found over specific piedmont plains, namely the Chos and Duars.
Understanding Piedmont Plains
Piedmont plains are large, relatively flat areas of land found at the base of mountains. They are formed by the deposition of sediments carried down by rivers flowing from the mountains.
Chos and Duars Formation
- The Chos are ephemeral streams found in the Sub-Himalayan region that carry large amounts of gravel and sand during heavy rainfall.
- The Duars are the floodplains and foothills of the eastern Himalayas in northeastern India, also shaped by river action.
Soil Deposition and Type
Rivers flowing down from the mountains onto these piedmont plains deposit sediments, including silt, sand, and clay. This process of deposition by rivers is characteristic of alluvial environments.
Therefore, the soil present over these piedmont plains, like the Chos and Duars, is primarily Alluvial soil. This soil is known for its fertility, making these regions agriculturally important.
Important Questions from Soils
- Which soil is acidic in nature and found in high rainfall areas?
Which of the following statements regarding Soil is/are FALSE?
1. Fertile soil supports plant growth by providing plants with nutrients, acting as a water holding body and serving as the substrate to which plants anchor their roots.
2. Vegetation, tree cover and forest prevents soil degradation and desertification by stabilizing the soil, maintaining water and nutrient cycling.
3. Grass found on pasture lands cannot protect the soil against soil erosion and also inhibits the soil biological activities.
Choose the correct answer from the options given below:With reference to the different types of soil found in India, identify the pairs which is/are wrongly matched.
1. Submontane soil - These are formed by the deposition of eroded material and are found in the Tarai region stretching from Jammu and Kashmir to Assam.
2. Karewa soil - These are the lacustrine deposits found in the Kashmir valleys and Bhadarwah Valley.
3. Peaty and Marshy soil - These are typical soils of the monsoon climate characterised by seasonal rainfall and is deficient in organic matter.
4. Laterite soil - These soils are rich in humus and organic matter.
Choose the correct answer from the options given below:Match List I with List II.
List – I (Pedogenic Process) List – II (Description) A. Podzolization I. It is associated with humid cold mid-latitude climates and coniferous vegetation B. Laterization II. It is associated with soils found in tropical and subtropical environments C. Calcification III. It is associated with warm, semi-arid environments, usually in grassland vegetation where evapotranspiration exceeds precipitation D. Gleization IV. It is associated with poorly drained and water logged areas of cold climates and peat is found in the upper portion of the soil Which of the following features are associated with Regur Soils in India?
1. It develops on crystalline igneous rocks as a result of intense leaching.
2. It is rich in Iron, Potash and Phosphoric contents.
3. It is typically found in north-west region of Deccan plateau and made up of lava flows.
4. It is rich in calcium carbonate, magnesium, potash and lime.
