Answer:
1.Soil texture: The alluvial soils vary in nature from sandy loam to clay. These soils are more loamy and clayey in the lower and middle Ganga plain and the Brahmaputra valley. The sand content decreases from the west to east
Explanation:
2.Alluvial soil is found in the northern plains beginning from Punjab to West Bengal and Assam. It is also found in deltas of different rivers such as Krishna, Godavari, Kaveri, and Mahanadi in peninsular India
3.mong the in situ soils of India, the black soils found in the lava-covered areas are the most conspicuous. Those soils are often referred to as regur but are popularly known as “black cotton soils,” since cotton has been the most common traditional crop in areas where they are found. Black soils are derivatives of trap lava and are spread mostly across interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan lava plateau and the Malwa Plateau, where there is both moderate rainfall and underlying basaltic rock. Because of their high clay content, black soils develop wide cracks during the dry season, but their iron-rich granular structure makes them resistant to wind and water erosion. They are poor in humus yet highly moisture-retentive, thus responding well to irrigation. Those soils are also found on many peripheral tracts where the underlying basalt has been shifted from its original location by fluvial processes. The sifting has only led to an increased concentration of clastic contents.
4.Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. ... Historically, laterite was cut into brick-like shapes and used in monument-building.may not be correct tho
arid soil Arid soil
Featured snippet from the web
Arid soils have surface horizons with several unique characteristics. Arid soil can be classified as a group of soils belonging to the aridisol order of USDA classification. ... The soil red and brown in colour. It is sandy in texture. It is saline in nature and lacks humus and moisture
forest soil
Forest soils form where it is not too hot, and not too cold. ... Soils that formed under deciduous forests are very fertile and productive agricultural lands because of the decomposing leaves at the soil surface. However, soils formed under pine trees are usually more acidic and sandy, and are less suited to growing crops.
6.Soil erosion is the displacement of the upper layer of soil, it is one form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.
7.Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded by wind and water. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. They can resemble malpaís, a terrain of volcanic rock
8.Sheet and rill erosion
The amount of hill slope erosion largely depends on how the land is used. Sheet erosion occurs when a thin layer of topsoil is removed over a whole hillside paddock—and may not be readily noticed. Rill erosion occurs when runoff water forms small channels as it concentrates down a slope.
