Factors determining the utility of natural resource are:

1. Availability:
The availability of natural resources is a crucial factor that determines their utility. The more abundant the resource, the more it can be used for various purposes. On the other hand, scarce resources tend to be more valuable and carefully utilized.

2. Accessibility:
The ease of access to natural resources is another factor that determines their utility. Resources that are easily accessible are more likely to be utilized than those that are difficult to reach. For example, oil reserves located in the middle of the ocean are harder to access than those located on land.

3. Quality:
The quality of the natural resource is also a significant factor. High-quality resources tend to be more valuable and useful for various purposes. For example, high-quality coal is more valuable than low-quality coal because it burns more efficiently.

4. Economic viability:
The economic viability of a natural resource is another factor that determines its utility. Resources that are too expensive to extract or process may not be economically viable to use, even if they are abundant and of high quality.

5. Environmental impact:
The environmental impact of natural resource utilization is an important consideration. Resources that have a significant negative impact on the environment may not be considered useful, even if they are abundant and of high quality.

6. Technological development:
Advances in technology can increase the utility of natural resources. For example, new drilling techniques can access oil reserves that were previously inaccessible, making them more useful.

7. Social and cultural factors:
Social and cultural factors can also influence the utility of natural resources. For example, some communities may value certain resources more than others, depending on their cultural traditions and beliefs.

In conclusion, the utility of natural resources depends on various factors such as availability, accessibility, quality, economic viability, environmental impact, technological development, and social and cultural factors. Understanding these factors is crucial in determining how natural resources are utilized and managed.

The two main factors are :- Time and value. Take the example of wheel. In ancient time people used to ride on the Bullock cart but nowdays there are trains and aeroplanes. In a bullock cart only for people could ride but now thousands of people can travel by trains. This was the example of time. In the early times, fire was used for lighting but now it is used in cooking foods. This was the example of value that shows how the utility has been changed.
