Oil is a natural liquid found beneath the Earth's surface, mainly used for producing fuels like gasoline, diesel, and jet fuel. It is also used to create products such as plastics and lubricants. Oil is considered a nonrenewable resource because it takes millions of years to form, and its extraction and burning can harm the environment by producing pollution. While it has been an important energy source for many years, efforts are being made to find cleaner and more sustainable alternatives.
