These soils develop a reddish colour due to diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form. Write four characteristics of laterite soils. Why are they called laterite? Write six states which have laterite soils and name the important crops which grow well in these soils. Crops which grow well in these soils are: tea, coffee and cashew-nuts. Write the main features of forest soils.

What are the different types of soils found in the hilly forested areas? Answer: Forest soils are mainly found in the hilly and mountainous areas where sufficient rain forests are available. The soil texture varies according to the mountain environment where they are formed. At least four types of soils can be seen in the hilly forested areas:.

What is soil erosion? Write the main causes of soil erosion. Answer: The denudation of the soil cover and subsequent washing down is described as soil erosion.

The process of soil formation and erosion goes on simultaneously and generally there is a balance between the two.

This balance is sometimes disturbed, leading to soil erosion. The main activities like deforestation, over-grazing, construction and mining and also natural agents like wind, running water and glacier are the main causes of soil erosion. Explain three types of soil erosion mostly observed in India. Mention human activities that are responsible for soil erosion. Write the land area degraded by gully erosion and name five states where gully erosion is very pronounced.

Evolving a planning structure endowed with appropriate technology, skill and institutional set up for implementing resource development plAnswer: Matching the resource development plans with overall national development plAnswer: Question There are regions which are rich in certain types of resources but are deficient in some other resources.

For example: Arunachal has abundance of water but lacks in infrastructural development. There are some regions which can be considered self sufficient in terms of availability of resources. There are some regions which have acute shortage of some vital resources. For example: The state of Rajasthan is well endowed with solar and wind energy but lacks in water resources. Answer: Four factors involved in the development of resources are: Availability of resources Level of technology Quality of human resources Historical experiences of the people Question Three reasons for conservation: Our resources are limited in nature, therefore they have to be frugally used.

Many of the resources are non-renewable in nature, therefore extra care has to be taken. Their conservation is necessary for our own sustenance and for the ongoing economic developmental processes. Indiscriminate use of resources by human beings has led to the depletion of resources for satisfying the greed of few individuals.

Irrational consumption and over-utilization of resources leads to socio-economic and environmental problems. Answer: At the international level, the Club of Rome advocated resource conservation for the first time in a more systematic way in Write the major features of Rio de Janeiro Earth Summit, The summit was convened for addressing urgent problems of: environmental protection and socio-economic development at global level.

Answer: The major land-use categories and their percentage share is: Net sown area, where regular agriculture is done � Forests, Barren and waste land � 6. Area under non-agricultural use � 7. Permanent pastures and grazing land � 3. Area under miscellaneous tree crops and groves � 1. Culturable waste land � 4. Reasons for marginal increase in forest area: increasing population technological developments expansion of agriculture development of transport and communication facilities overgrazing felling of trees All these exert great pressure on land thus causing further depletion of forests.

Reasons: Because the land-use reporting for most of the north-eastern states, except Assam, has not been done. Some areas of Jammu and Kashmir occupied by Pakistan and China have not been surveyed. Answer: Two reasons are: These lands may be of poor quality. The cost of cultivation of such lands is very high. Net Sown Area because: They are agriculturally rich States because of favourable climatic conditions for the growth of crops and levelled fertile nature of land.

Irrigation facilities are well-developed here. States with low N. Economic backwardness and climatic conditions also do not encourage large scale agricultural activities. Reasons: It is considered essential for the maintenance of ecological balance. The livelihood of millions of people who live on the fringe of these forests depends on these forests.

Four categories of waste-lands: Water eroded area.. Write six human activities which have caused land degradation. Answer: Deforestation Overgrazing Mining activities � mining sites are abandoned after excavation leaving deep scars and traces of over-burdening.

Mineral processing produces large quantities of dust in the atmosphere, which on settling down on land, retards the process of infiltration of water into the soil. Over-irrigation leads to waterlogging which increases salinity and alkalinity in the soil. Industrial effluents � such wastes cause land and water pollution. Answer: Difference between biotic and abiotic resources Biotic resources Abiotic resources i The resources which are obtained from biosphere are biotic resources.

Name three states each in which land degradation is caused due to over-irrigation over-grazing deforestation due to mining activities Answer: Three states where over-irrigation has resulted in land degradation are Punjab, Haryana and Western Uttar Pradesh.

Due to over-grazing. Gujarat, Rajasthan, Madhya Pradesh and Maharashtra. Deforestation due to mining activities has led to land degradation in Jharkhand, Chhattisgarh, Madhya Pradesh.

Avoid overuse of fertilisers and pesticides. Soil As A Resouce Question It is an important resource because: It is the medium of plant growth. It supports different types of living organisms on earth. Factors responsible for soil formation are: Parent rock or bed rock on which the soils are formed, disintegrate and decompose under the process of weathering and erosion.

Climate: It determines the rate of weathering. Relief, vegetation, other forms of life and time are other important factors in the formation of soils. Various forces of nature such as change in temperature, actions of running water, wind and glaciers, activities of decomposers etc. Chemical and organic changes which take place in soil, also play a role in its formation. Answer: Factors: Varied relief features Varied land forms Varied climatic realms Varied vegetation types.

Answer: Basis of classification of soils: Colour Thickness Texture Age Chemical and physical properties Factors responsible for soil formation. Answer: Alluvial soil Red and yellow soil Black soil Laterite soil Arid soil Forest and mountainous soils Alluvial soil is the most widely spread soil. Bangar Khadar i It is old alluvial soil. Write the main characteristics of alluvial soils.

Answer: Alluvial soils as a whole are very fertile. They consist of various Important Question Of Geography 10th Class Sub proportions of sand, silt and clay. They contain adequate proportion of potash, lime and phosphoric acid. They are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.
