Propane, pentane, ethane, hexane, and butane are all present in trace levels in natural gas. Carbon and hydrogen atoms combine to create the gas known as methane.
Phytoplankton and zooplankton are two different types of plankton that are related to both plants and animals. Natural gas are microscopic plankton in their natural forms. Sediment is the term used to describe plankton on materials that enter the ocean through rivers. Then, as this debris falls to the ocean floor, natural gas is created.
