It is also found in Rajasthan, Gujarat and eastern coastal plains particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers. (iii) Matching the resource development plans with overall national development plans. The soil texture is loamy and silty in valley sides and coarse grained in the upper slopes. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are finer in texture. Soil texture varies according to the mountain environment. They develop deep cracks during hot weather, which helps in the proper aeration of the soil. Non-Renewable Resources occur over a very long geological time. The renewable resource may further be divided into continuous or flow. Rivers transport eroded material from their higher reaches and deposit this material on their banks as they reach the plains. On the basis of factors responsible for soil formation colour, thickness, texture, age, chemical & physical properties, the soil of India can be classified in different types. Eg: Hydrogen can be used as a rich source of energy. To overcome irrational consumption and over-utilisation of resources, resource conservation at various levels is important. Potential Resources are the resources which are found in a region but have not been utilised. Human beings themselves are essential components of resources. Keep Learning and stay tuned for more updates on CBSE and NCERT. Soil erosion is also caused due to defective methods of farming. Or India has approximately 89000 species of animals, 1200 of birds and 2500 species of fishes. The resources which can be renewed or reproduced by physical, chemical or mechanical processes are known as Renewable or Replenishable Resources. The laterite soil develops in areas with high temperature and heavy rainfall. In lower regions soil has Kankar in it because of the increasing calcium content. Plain surface is best for the formation of soil because least problems are created here during the formation. (a) Area: Alluvial soil covers about 43.7% of the total land area under cultivation. It encompasses a rather diverse range of soils, which are nevertheless widespread in many parts of Australia. ICSE solutions for ICSE Class 10 Geography chapter 4 (Soils in India) include all questions with solution and detail explanation. For example, a sandy loam (SL) is a loam with a high sand content.

Soil Profile (d) Soil Texture. 38 Litter thickness, drainage, soil texture and structure, and Munsell colour were noted. The classification of soils is based on origin, colour, composition, texture and location. Black soil is nutrients rich and contains calcium carbonate, magnesium, potash and lime. Black Soil (Regur) Composition: Rich in lime, aluminium, calcium, potash, iron, magnesium. When water flows as a sheet over large areas down a slope and the topsoil is washed away, it is known as sheet erosion. Alluvial soil is a mixture of sand, silt and clay.

Such soils are more common in piedmont plains such as Duars, Chos and Terai. This soil is the result of intense leaching due to heavy rain.
