For example, air, sunlight, and water are abiotic natural resources. Considering their stage of development, natural resources may be referred to in the following ways:.

Coal is estimated to be able to last less than more years. One of the issues is that as countries such as China increase their demands on the coal supply it will dwindle faster.
Coal is also the major source of air pollutant in the world so there is much discussion about regulating its usage. The problem is it is one of the cheapest sources of fuel for industrial applications. The general estimate is that with the projected rate of consumption of oil supplies and known resources that there is enough to last for more years.
Even if new fields and methods of oil extraction are discovered, geologists project that it would be impossible for the Earth to have an unlimited supply of oil. It takes millions of years for oil to be created; there is no way of speeding up that process. Natural gas reserves are doing only slightly better than oil, it is estimated that there is enough to last for 60 years.
Gas is a much cleaner fuel source than oil, which has led to an increased level of consumption of it as an alternative fuel, but it still stands to run out quickly.
Phosphorus comes from phosphate rock and is used to grow all of our food and crops. The projected lifespan of the current known resources is about a years. There has not been significant research in developing new and safe fertilizers that can be effective replacements for phosphorus.
Other minerals like gypsum, bauxite, phosphate, bentonite, mica, titanium, zirconium are found in sea beds along the coastal plains. Rare earth elements like scandium and terbium are two of the earth powerful minerals that are used in wind turbines and electronic circuits in smartphones. Coastal plains contains deposits of potassium carbonate and rare elements like cerium and neodymium.
Iron is also in limited supply. It is made from elements such as silica which then have to be heated to create the pig iron that industrialization depends on. Iron was the most important natural resource on earth during ancient ages. In this scenario, the tree is the raw material. Every item in your home was made from a raw material that came from a natural resource.
The tea mug, electricity at home, bread, clothes, you name them: Natural resources come in many forms. It may be a solid, liquid or gas. It may also be organic or inorganic. It may also be metallic or non-metallic. It may be renewable or non-renewable.
Natural resources are useful raw materials that we get from the Earth. They occur naturally, which means that humans cannot make natural resources. They occur naturally, which means that humans cannot make natural resources. Introduction to natural resources (NR) Ever since the earth was inhabited, humans and other life forms have depended on things that exist freely in nature to survive. These things include water (seas and fresh water), land, soils, rocks, forests (vegetation), animals (including fish), fossil fuels and minerals. natural resource in Science natural resource Something, such as a forest, a mineral deposit, or fresh water, that is found in nature and is necessary or useful to humans.
