a. Potential b. Renewable

c. Actual d. Localised​

Answer 1

Answer:

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.

Resources are usually classified into three types, viz. natural, human made and human resources.

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.
