Oil and gas are natural resources found deep beneath the Earth's surface. They are formed from the remains of ancient plants and animals that have been buried and subjected to heat and pressure over millions of years. These fossil fuels are extracted through drilling and are used primarily for energy production, transportation, and heating. Oil is a thick, black liquid, while natural gas is a colorless, odorless gas. Both are crucial for modern economies, powering vehicles, heating homes, and generating electricity. Additionally, they are used in the production of various products, including plastics and fertilizers.
