What are the types of resources

Resources are usually classified into two types,  natural and human made
Natural Resource: Resources which are obtained from nature are called natural resources. Some of the natural resources can be used directly, while for using some others we need the help of some technologies .
Human Made Resources: When a natural resource undergoes drastic change by human intervention, it becomes human-made resource. For example; iron ore is processed to make steel and hence steel is a man-made resource. Buildings, bridges, railways, machines, etc. are examples of human-made resources. Technology is also a human-made resource.

Resources can be classified on the basis of origin as :

Biotic and abiotic resources

On the basis of exhautibility as:

Renewable and non-renewable

On the basis of status of development as:

Potential, developed stock and reserves
