two sources of energy for the earth system

Earth as a Source of Elements - Most elements are formed due to fusion of simple nuclei to give heavier nuclei i.e., nucleosynthesis or nuclear fusion reactions taking place in the stars. Atoms of these elements began to fall together about six billion years ago to form a s..

Identification of Alternative Sources - Fossil fuels are the major source of energy on Earth. With the development of technology, the worlds consumption of the concentrated sources of energy like coal, petroleum and natural gas and uranium..

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy get..
