Answer:
A resource is a source or supply from which a benefit is produced and that has some utility. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. ... An item becomes a resource with time and developing technology.
Answer:
Stock resources (non-renewable)
These resources have taken millions of years to form and so they are finite (can be exhausted), which is why we call them non-renewable – they are not going to be replenished in the near future. (Whilst new coal or gas may be created over millions of years, this is not useful on a human timescale). Some stock resources may have their exploitable life extended, while others are consumed in a single use, such as fossil fuels; metals, such as copper and steel may be recyclable and re-used. Examples of stock resources include fossil fuels (coal, oil, gas) as well as minerals such as gold, copper, tin, uranium etc.
Flow resources (renewable)
In contrast to stock resources, flow resources are renewed within a short timescale, either through natural physical systems or biotic reproduction. Some flow resources require careful management by human society in order to ensure their continuous availability, such as fish stocks or forests. These are known as critical flow resources. If these are exploited too intensively such that they can no longer be renewed, then they become stoc
