Question

How can a substance become resource​

Answer 1

Answer:

Resource: Anything which has some utility for us is called a resource. Some resources have economic value, while some do not. For example; milk has economic value, but a beautiful landscape has no economic value. But both are important because both satisfy some human needs.

Time and technology are two important factors which can change a substance into resources. For example; petroleum was not a resource before people learnt to use it.

Answer 2

Answer:

A substance becomes a resource when it is used to satisfy human needs and demands for survival.
