- | Elements than have been produced by nature, without the intervention of man. | + | Natural Elements are those elements that have been produced by nature, without the intervention of man. |

+ | **Electricity** can be produced from Fossil Fuels, Water and gravitational force (Hidroelectricity), Wind, Sun (Solar), Geothermal energy, Biomass and waves, and tides. | ||
+ | |||
+ | Radiation from the sun is also an important source of **heat** that can be used to heat water for domestic or industrial uses. Geothermal energy is also a source of heat, but it is available only in some geographical spots. Biomass is also a source of heat. | ||
+ | |||
+ | **[[Fossil fuels]]** play an important role in the economy since they are extensively used to produce electricity, heat, and motion. Fossil fuels are [[non renewable resources]], since they were produced naturally millions of years ago, and are not renewed after it's usage. | ||

+ | ===== Difference Between Natural Elements and Natural Resources ===== | ||
+ | |||
+ | Natural elements are elements that are provided by nature without human intervention, like the wind and the water. | ||
+ | |||
+ | Natural resources are those natural elements that can be used by us. For example, we can drink water and use the wind to produce energy. | ||
+ | |||
+ | There are natural elements that cannot be considered natural resources, like ore that is inaccessible to mankind. | ||
+ | |||
+ | We have created the following plot to show that natural resources are a subset of natural elements: | ||
