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.

13. Resource Planning : It is a technique or skill or proper utilisation of resources.

15. Soil Erosion : The removal of soil by the forces of nature, particularly wind and water.
