How is oil formed?
il is formed fromthe accumulationof hydrocarbons.Hydrocarbons
accumulate naturally, thousands of feet below the surface of the
Earth, from the decomposition of organic materials like plants and
marine animals which died during the Palaeozoic Era (between 245 and
544 million years ago).
Trapped beneath the ground under enormous pressure and high
temperatures, these hydrocarbons were compressed and eventually
transformed into crude oil after millions of years.
High temperatures and pressure
transform dead organism into oil.
Dead organisms
get trapped underground
