Petroleum, also known as crude oil, is a yellowish-black liquid found deep underground. It is made up of tiny dead plants and animals that lived millions of years ago! 🌍
When these organisms decomposed, they turned into oil over time under pressure and heat. You can find petroleum in many parts of the world, especially in countries like Saudi Arabia, Russia, and the United States. It is used for many things, including fuel for cars, heating our homes, and making products like plastics! 🚗🏠 Understanding petroleum helps us learn about energy, the environment, and how we use resources wisely.
