1. What are natural resources? Classify the natural resources based on their availability.

Natural resources are resources that exist without actions of humankind. This includes all valued characteristics such as magnetic, gravitational, electrical properties and forces, etc. On Earth it includes sunlight, atmosphere, water, land (includes all minerals) along with all vegetation, crops and animal life that naturally subsists upon or within the previously identified characteristics and substances.

Particular areas such as the rainforest in Fatu-Hiva are often characterized by the biodiversity and geodiversity existent in their ecosystems. Natural resources may be further classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level).

A natural resource may exist as a separate entity such as fresh water, air, and as well as any living organism such as a fish, or it may exist in an alternate form that must be processed to obtain the resource such as metal ores, rare-earth metals, petroleum, and most forms of energy.

There is much debate worldwide over natural resource allocations. This is particularly true during periods of increasing scarcity and shortages (depletion and over consumption of resources).

Classification:

There are various methods of categorizing natural resources, these include source of origin, stage of development, and by their renew ability.

On the basis of origin, natural resources may be divided into two types:

·       Biotic — Biotic resources are obtained from the biosphere (living and organic material), such as forests and animals, and the materials that can be obtained from them. Fossil fuels such as coal and petroleum are also included in this category because they are formed from decayed organic matter.

·       Abiotic – Abiotic resources are those that come from non-living, non-organic material. Examples of abiotic resources include land, fresh water, air, rare earth metals and heavy metals including ores, such as, gold, iron, copper, silver, etc.

Considering their stage of development, natural resources may be referred to in the following ways:

·       Potential resources — Potential resources are those that may be used in the future—for example, petroleum in sedimentary rocks that, until drilled out and put to use remains a potential resource

·       Actual resources — Those resources that have been surveyed, quantified and qualified and, are currently used—development, such as wood processing, depends on technology and cost

·       Reserve resources — The part of an actual resource that can be developed profitably in the future

·       Stock resources — Those that have been surveyed, but cannot be used due to lack of technology—for example, hydrogen

Many natural resources can be categorized as either renewable or non-renewable:

·       Renewable resources — Renewable resources can be replenished naturally. Some of these resources, like sunlight, air, wind, water, etc. are continuously available and their quantities are not noticeably affected by human consumption. Though many renewable resources do not have such rapid recovery rate, these resources are susceptible to depletion by over-use. Resources from a human use perspective are classified as renewable so long as the rate of replenishment/recovery exceeds that of the rate of consumption. They replenish easily compared to Non-renewable resources.

·       Non-renewable resources – Non-renewable resources either form slowly or do not naturally form in the environment. Minerals are the most common resource included in this category. From the human perspective, resources are non-renewable when their rate of consumption exceeds the rate of replenishment/recovery; a good example of this are fossil fuels, which are in this category because their rate of formation is extremely slow (potentially millions of years), meaning they are considered non-renewable. Some resources actually naturally deplete in amount without human interference, the most notable of these being radio-active elements such as uranium, which naturally decay into heavy metals. Of these, the metallic minerals can be re-used by recycling them, but coal and petroleum cannot be recycled. Once they are completely used they take millions of years to replenish.

2. What is a mineral and describe its types? Describe the importance of mineral resources.
