Explanation Statement 1 is correct: Submontane soils are formed when materials like rocks, minerals, and organic matter are carried down by water from the mountains (erosion). These materials are deposited in the foothills or lower areas of mountain ranges, creating fertile soil. The soil here is made up of a mixture of sand, silt, and clay, which makes it well-draining and suitable for agriculture.
Statement 2 is not correct: Submontane soils are not particularly deficient in lime and are not usually acidic. This statement is more applicable to other soils like laterite or red soils which tend to be more acidic and deficient in lime.
Statement 3 is correct: Submontane soils are fertile and support dense forest growth due to the richness in nutrients. These soils are also prone to soil erosion because they are found in the foothills, which are usually areas of steep slopes. When vegetation is removed or damaged, heavy rainfall can easily wash away the topsoil, leading to soil erosion.This makes erosion a significant concern in these areas.
