However, 97 percent is held in the oceans, while only 3 percent is freshwater. Of the freshwater, only 1 percent is easily accessible as ground or surface water, the remains are stored in glaciers and icecaps.
There are various methods of categorizing natural resources, these include source of origin, stage of development, and by their renewability.
On the basis of origin, natural resources may be divided into two types: Biotic — Biotic resources are obtained from the biosphere living and organic materialsuch as forests and animalsand the materials that can be obtained from them.
Fossil fuels such as coal and petroleum are also Earth s natural resource water 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 landfresh waterairrare earth metals and heavy metals including ores such as goldironcoppersilveretc. 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 processingdepends 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. Though many renewable resources do not have such a rapid recovery rate, these resources are susceptible to depletion by over-use. 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. 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.
Extraction[ edit ] Resource extraction involves any activity that withdraws resources from nature. This can range in scale from the traditional use of preindustrial societies, to global industry. Extractive industries are, along with agriculture, the basis of the primary sector of the economy.
Extraction produces raw materialwhich is then processed to add value.
Examples of extractive industries are huntingtrappingminingoil and gas drillingand forestry. Extractive industries represent a large growing activity in many less-developed countries but the wealth generated does not always lead to sustainable and inclusive growth.
People often accuse extractive industry businesses as acting only to maximize short-term value, implying that less-developed countries are vulnerable to powerful corporations. Alternatively, host governments are often assumed to be only maximizing immediate revenue.
Researchers argue there are areas of common interest where development goals and business cross. These present opportunities for international governmental agencies to engage with the private sector and host governments through revenue management and expenditure accountability, infrastructure development, employment creationskills and enterprise development and impacts on children, especially girls and women.
Exploitation of natural resources In recent years, the depletion of natural resources has become a major focus of governments and organizations such as the United Nations UN.
Unless we solve that problem, it will avail us little to solve all others. Considering most biodiversity are located in developing countries,  depletion of this resource could result in losses of ecosystem services for these countries.Natural resources from the Earth fall into three classifications: renewable, non-renewable and flow resources.
Air, water, soil, metals and minerals are all natural resources. So are Earth's energy resources, which include fossil fuels, geothermal, tidal, wind and solar energy, and biological resources such as plants, trees and animals. Water resources are sources of water that are useful or potentially useful to humans.
It is important because it is needed for life to exist. Many uses of water include agricultural, industrial.

Earth’s Resources: Air and Water Strand Earth Resources Topic Five senses and Earth’s natural resources discuss again that the pollutants are still in Earth’s air, just not in a concentrated area. Earth's Natural Resources provides a thorough overview of the subject and details how natural resources relate to individuals and our society.
It discusses how the Earth's natural resources form and change over time and how they are extracted for human use.
