  1. RESOURCES RESOURCES All materials available in our environment which satisfy our needs are called as Resources. O All resources have some value. Value means worth. Some resources have economic value and some do not, but both are important and satisfy human needs. 0 Some resources can become economically valuable with time. Time and technology are the important factors that change substances People themselves are the most important resource. It is their ideas, knowledge, inventions and discoveries that lead to the creation of more resources. Each discovery or invention leads to many others. For example- Discovery of fire led to the practice of cooking Invention of the wheel resulted in the development of newer modes of transport.


  2. TYPES OF RESOURCES: Resources are catogorised into natural, human made and human. 1. Natural resources are those resources that are drawn from nature and are used without much modification-air, water, soils, minerals are the natural resources Natural resources are classified into different groups depending upon their level of development and use, origin, renewability and distribution Natural resources also called as 'gifts of nature'.
