How and when was oil formed? Make your answer simple and relevant and I will definitely mark you the brainliest! :D

Answer 1

Answer:

The formation of oil begins in warm, shallow oceans that were present on the Earth millions of years ago. In these oceans, extremely small dead organic matter - classified as plankton - falls to the floor of the ocean. This plankton consists of animals, called zooplankton, or plants, called phytoplankton. This material then lands on the ocean floor and mixes with inorganic material that enters the ocean by rivers. It is this sediment on the ocean floor that then forms oil over many years. The energy in oil initially comes from the Sun, and is energy from sunlight that is trapped in chemical form by dead plankton.
