Fossils are remains, tracks, impressions, or traces of organisms that existed in the past. These are the remains or impression of prehistoric animals and plants that were embedded in the rocks.These remain also embedded in volcanic ash, sedimentary rocks, peat, amber, etc ., and get preserved and are an important tool for evolutionary studies.

Fossils are the remains or impression of prehistoric animals and plants that were embedded in the rocks. The study of fossils is known as palaeontology. It is a branch of science in which age, formation, and significance of fossils are being studied. The age of fossil if determined by performing a method called radiometric dating.

Fossils are the remains or traces of ancient life that have been preserved by natural processes, from spectacular skeletons to tiny sea-shells. A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.

Renewable sources: Wind, solar energy, hydrogen. A renewable resource, also known as a flow source, is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. Non-renewable: Coal, petroleum, natural gas. A non-renewable resource (also called finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels.
