Final answer:
Petroleum (oil) was first discovered in the U.S. in Titusville, Pennsylvania in 1859. The first products uses of petroleum were for kerosene lamps and as a fuel for internal combustion engines. Today, petroleum is primarily used as a fuel for transportation and in the manufacturing of plastics.
Step-by-step explanation:
Petroleum (oil) was first discovered in the U.S. by Edwin L. Drake in Titusville, Pennsylvania in 1859.
The first products uses of petroleum were for kerosene lamps, which were widely used for lighting in the late 19th and early 20th centuries. Petroleum was also used as a fuel for the first internal combustion engines, such as Karl Benz's gasoline-powered automobile in 1885.
Today, petroleum is primarily used as a fuel for transportation, but it is also used in the manufacturing of plastics and other synthetic compounds.
