Non-renewable Resources : Resources which takes million years of time to replenish are called non-renewable resources. For example – fossil fuels. We must remember that some resources like metals are recyclable. 

Question : Mention any three features of arid soils.
Answer : (i) Arid soils range from red to brown in colour.

Question : Suggest any three methods of soil conservation suitable to Indian conditions.
Answer : Methods of soil conservation :
(i) Ploughing along the contour lines can decrease the speed of water flow down the slopes.
(ii) Step or terrace cultivation on slopes restricts erosion. Western and central Himalayas have well- developed terrace farming areas.
(iii) Strip cropping : Here large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind.
(iv) Shelter belt plantation : Trees are planted in rows. These shelter belts have led to the stabilisation of sand dunes and in stabilising the desert in western India.

Long Questions for Class 10 Social Science Forest and Wildlife Resources

Question : Discuss the factors responsible for land degradation in India.
Answer : The important factors responsible for land degradation in India are as follows :
(a) Deforestation : By an estimate over one million hectares of forest is lost every year in India.
(b) Erosion: Loss of vegetation cover makes land more susceptible to erosion. Wind and water have left vast tracts of land barren. Water erodes top soil to an extent of around 12,000 million tons per annum.
(c) Over-Irrigation : Successive cropping and over-irrigation, leads to water-logging and consequent salinization and alkalization. This situation mainly arises due to poor drainage.
(d) Floods and Droughts: Drought is both man- made and environment-induced. Man has played a key role in the creation of drought-prone areas by over-exploitation of natural resources like forests, degradation by grazing, excessive withdrawal of ground water, silting of tanks, rivers, etc.
Floods, on the other hand, are caused by heavy rains in a very short period. Each situation could have been altered had there been good vegetation cover. Vegetation helps in reducing run-off, increasing infiltration and reducing soil erosion.
(e) Over-grazing: India has the worlds largest cattle population, but not enough pasture land. This has led to serious problems as animals have encroached into forest lands and even agricultural lands. Land degradation due to overgrazing leads to desert like conditions.
(f ) Pollution -Pollution of land is caused by disposal of solid waste, refuse from domestic, industrial and agricultural sectors. Another major source of land pollution is the creation of derelict land due to mining particularly due to surface and underground mining activities.
