3 types of fossil dating 100datingsitezone com
If one were to sum up the entire global environmental crisis in two words, indeed fossil fuels takes center stage.
It is the keystone, the consequential essence of nearly everything discussed in matters of energy and the environment, a single point that every transient environmental line of thought eventually leads.
Additionally, the seas were littered with hoards of photosynthetic algae that continued to sequester carbon in a carbon dioxide (CO) rich atmosphere.
It is believed that plant matter and marine organisms during this swamp filled period eventually sank to the bottom of the earth under immense pressure to gradually form the majority of the fossil fuels that are extracted today.
Additionally, there is record of the Hopi Indians of the North American Southwest using coal as a heat source to cook and make pottery.
Until this point, however, coal was never a prominent source of fuel and instead wood charcoal was the mainstream staple.
The earths biomass, however, is most concentrated in plant matter and micro-organisms which were one of the first organisms to ever originate on planet earth.
Fossils are important for working out the relative ages of sedimentary rocks.A fossil is familiar to us as some organism that has been preserved over time that can be carefully dug up, collected and sent to the nearest natural history museum to awe the public.Most fossils that we are used to understanding are actually gargantuan in size, the size of shelled organisms and insects.Some of the most useful fossils for dating purposes are very small ones.For example, microscopic dinoflagellates have been studied and dated in great detail around the world.
The history of fossil fuels is characterized by transition points in usage, and the first such transition occurred during the onset of the Industrial Revolution in which the birth of manufacturing produced a dire need for a new energy source.
