Forests and Life
To a vast number of tribal people, the forest is a home, a livelihood, their very existence. It provides them food, fruits of all kinds, edible leaves, honey, nourishing roots and wild game. It provides them with material to build their houses and items for practicing their arts. The importance of forests in tribal economy is well-known as they are the source of sustenance and livelihood for tribal communities. It is commonly believed that the tribal communities live in harmony with nature and protect forests. Out of a total of 593 districts 188 have been identified as tribal districts. The tribal districts account for about 59.61 per cent of the total forest cover of the country whereas the geographical area of 188 tribal districts forms only 33.63 per cent of the total geographical area of the country.
It demonstrates that tribal districts are generally rich in forest cover. Forest and tribal are very closely related. The age-old knowledge of tribal regarding forestry can be used in the development of forests. Rather than treating tribal as minor forest produce collectors they should be made growers of minor forest produce and encouraged to participate in conservation.

* Thickness of the atmosphere is great at the equator because it is transported to great heights by a strong conventional current.
* this layer contains dust particles and water vapour
* all changes in climate and weather take place in this layer.
* the temperature in this layer decreases at the rate of 1 Degree Celsius for every 165 M of height.
* all biological activities take place in this layer
6. Biodiversity is important not only for geographers but also for economists. How?
Biodiversity is equally important for geographers and economist in this way.
* crop diversity

Etc.
9. Different regions exhibit different types of erosion. Substantiate it with suitable examples.

* in region with heavy rainfall and is steep slopes erosion by running water is more significant.
* Water used in which is more serious and extensively in different parts of India, takes place many in the form of sweet and gully erosion.
* sheet erosion takes place on level lands after heavy shower and the soil removal is not easily noticeable.
* ravines are widespread in the Chambal basin. Besides this, they are also found in Tamil Nadu and West Bengal, the country is Losing about it thousand hectares of land to ravens every year.
