Natural Resources

Natural resources are the elements which occur naturally. They help to create materials to produce energy or elements to build things. There are two kinds of natural resources:


1) Renewable Resources: They are those that can be replaced in nature without finish. Some of them are: plants, animals, forest and natural fonts of energy such as: wind, water, waves, solar light, etc.





2) Non-renewable Resources: They are those that cannot reproduce again. In comparison with the renewable resources, these delay one thousand year or one million year to appear again. Some of them are: metals (iron, copper, gold, silver, etc.), fossil fuel (petroleum, natural gas) and even some trees due to their growth time.
