Petroleum is a mixture of plant and animal remains compressed together and heated under the Earth's crust. Petroleum occurs naturally as a liquid after millions of years of this process. Petroleum is harvested by drilling into underground wells and then is filtered to become crude oil, which can be converted, once again, into various fuel or household products. These products range from gasoline to asphalt and even include the medicinal compounds created with petroleum jelly.
