How is potrollium formed?

Answer 1

Potrollium is not a real substance or term in the field of geology or chemistry. It appears to be a made-up or misspelled word. If you meant to ask about petroleum, it is formed from the remains of ancient plants and animals that were buried and subjected to heat and pressure over millions of years in the Earth's crust. This process transforms the organic matter into hydrocarbons that make up petroleum.
