Geography

1. Abiotic Resources : All those resources which are composed of non living things eg. land, water, soil.
2. Afforestation : It means planting trees.
3. Biotic Resources : All those resources which have life. Eg. Forest and their product agricultural crop, animals and birds, marine life.
4. Conservation : It means judicious and planned use of natural resource so that we can get the greatest possible benefit from these resources over the longest possible period of time.
5. Fallow land : It is a cultivable land which is being allowed to rest, uncropped or partially cropped for one or more reason so that it can regain its fertility.
6. Gully Erosion : It takes place when running water cuts deep ravines in the absence of vegetation. It makes soil unfit for cultivation.
7. Land degradation : Rendering the land unfit for cultivation is called degradation of land.
8. Renewable Resources : These are the resources which can be renewed or reproduced by physical, mechanical, chemical processes in a given period of time. eg. solar energy, forest, agricultural product.
9. Man made Resources : These are those resources which are created by human beings with the help of machines.
10. Natural Resource : Resources which are endowment/gift of nature. eg. River, mountain, land, vegetation, minerals.
11. Non-renewable Resources : There are those resources which once used, cannot be replenished. eg. coal, petroleum, minerals etc.
12. Ravine : This is a land which is unsuitable for cultivation due to soil erosion.
13. Resource Planning : It is a technique or skill or proper utilisation of resources.
14. Soil : The upper most layer of the earth’s crust, which is loose fragmented and useful for growing plants is called soil.
15. Soil Erosion : The removal of soil by the forces of nature, particularly wind and water.
16. Resources : Object or things in the environment that fulfill the basic needs of man. These are technologically accessible, economically feasible and culturally acceptable.
17. Resource Development : An exercise that makes it possible to utilise the available natural resources for human satisfaction.
18. Contour ploughing : Ploughing along the contour lines instead of up and down the slope.
19. Sheet Erosion : Erosion of the top soil along gentle slopes caused by rain water.
20. Bad land : Land which is unsuitable for cultivation.
21. Leaching : Process of carrying away of soil nutrients by rain water.
22. Net sown area : It is the area sown with crops at least once is any of the crop season of the year but counted only once.
23. Shelter belts : Rows of trees which are planted in between the crops are known as shelter belts.
24. Stock : These are the materials in the environment which have the potential to satisfy the human needs, but could not be used as the human beings do not have the appropriate technology.
