99 free Fossil Fuels trivia questions with answers — science & nature quiz, new questions added Oct 2026.
Fossil fuels still supply most of the world's energy, and the story of how we found, fought over and burned them is full of odd detail: a driller given a fake military title to impress a town, a gas field shut down by the tremors it caused, and a benchmark crude named after a bird. This quiz covers the geology of how coal, oil and gas formed, the first wells and gushers, the rise and break-up of the great oil trust, OPEC and the 1973 embargo, fracking and shale, LNG, the barrel and the benchmarks, pipelines and supertankers, mining and rig disasters, and the dates that mark coal's decline. It suits students revising energy topics, pub-quiz setters and anyone curious about where the fuel in the tank and the power in the socket actually come from.

Q 01Petroleum formed mainly from the buried remains of which organisms, cooked by heat and pressure?
Zooplankton and algae
Zooplankton and algae, not dinosaurs, are the raw material of oil. Their remains settled on ancient seabeds and were buried under sediment before heat and pressure slowly cooked them into crude.
Q 02An oil barrel, a standard firmly established by 1872, holds exactly how many US gallons?
42
42 US gallons, about 159 litres, is the oil barrel, though no physical barrel of that size is used to ship crude today. The 55-gallon steel drum people picture is a different container.
Q 03Which smelly additive was put in natural gas after the 1937 New London school explosion in Texas?
Mercaptan
Mercaptan, an odorous compound also called thiol, was added to natural gas within weeks of the blast. Odourless gas had leaked under the school unnoticed, and Texas ordered all supplies odorised.
Q 04What happened to the price of WTI crude for May delivery on 20 April 2020, for the first time ever?
It turned negative
It turned negative, settling near minus $37 a barrel, because the main US storage hub was nearly full and nobody wanted to take delivery. Demand had collapsed during the pandemic.
Q 05Seawise Giant, at 458 metres the longest self-propelled ship ever built, was what kind of vessel?
An oil supertanker
An oil supertanker, Seawise Giant was longer than the Petronas Towers are tall and too deep-laden to use the Suez or Panama canals or the English Channel. It was later renamed Jahre Viking and Knock Nevis.
Q 06OPEC moved to which city in 1965, after Switzerland declined to extend its diplomatic privileges?
Vienna
Vienna has hosted OPEC since 1 September 1965, after five years in Geneva. A decade later, in December 1975, the oil ministers were taken hostage at their Vienna conference.
Q 07Arab oil producers declared the October 1973 embargo on supporters of Israel during which war?
Yom Kippur War
The Yom Kippur War of October 1973 triggered the OAPEC embargo, which targeted any country that had backed Israel at any point in the conflict. Prices soared and petrol queues followed.
Q 08Which oil magnate was hailed as America's first billionaire in 1916?
John D. Rockefeller
John D. Rockefeller was proclaimed a billionaire five years after the Supreme Court dismantled his trust; the breakup had proved immensely profitable for him as the successor companies' value soared.
Q 09To ship natural gas by sea as LNG, it is chilled into a liquid at roughly what temperature?
About −162 °C
About −162 °C turns natural gas into a liquid that can be shipped at close to atmospheric pressure in insulated tankers. The first such cargo crossed the Atlantic in 1959.
Q 10The word petroleum, coined in Medieval Latin, literally means what?
Rock oil
Rock oil is the literal sense: Latin petra means rock and oleum means oil. The company behind Edwin Drake's 1859 well was first called the Pennsylvania Rock Oil Company.
Q 11The Nord Stream pipelines, laid to carry Russian gas straight to Western Europe, run under which sea?
Baltic Sea
The Baltic Sea floor carries both Nord Stream lines; on 26 September 2022 underwater explosions left three of their four pipes inoperable.
Q 12Piper Alpha, whose 1988 blast killed 167 in the worst ever offshore oil disaster, stood in which sea?
North Sea
The North Sea platform, 120 miles north-east of Aberdeen, was pumping about a tenth of the region's oil and gas when a gas leak ignited on the night of 6 July 1988. The rig was completely destroyed, and 30 of the dead were never found.
Q 13The Athabasca oil sands, one of Earth's biggest heavy-crude deposits, lie in which Canadian province?
Alberta
Q 21Which country pumped more crude oil in 2023 than any nation had in any earlier year?
United States
The United States averaged a record 12.9 million barrels a day in 2023, more than any nation in history, as the shale boom reversed what had looked like a permanent decline since 1970.
Q 22The 1910 Lakeview Gusher, the largest accidental oil spill in history, erupted in which US state?
California
California's Kern County took the flood: the blowout ran for 18 months and released about 9 million barrels of crude, far more than Deepwater Horizon. The site is now a state historical landmark.
Q 23Which country's retreating army set fire to about 700 Kuwaiti oil wells in 1991?
Iraq
Alberta's Athabasca sands hold bitumen too thick to flow like ordinary crude, so shallow deposits are strip-mined and deeper ones are loosened with injected steam.
Q 14Which G7 country became the first to end coal-fired electricity when its last coal plant closed in 2024?
Britain
Britain shut Ratcliffe-on-Soar in Nottinghamshire on 30 September 2024, ending 142 years of coal-fired electricity in the country that pioneered it.
Q 15Kerosene displaced which lamp fuel from American homes during the 1860s?
Whale oil
Whale oil, especially from sperm whales, had lit indoor lamps outside the gas-piped cities until kerosene undercut it. By the 1860s the American illuminating-oil industry had switched over completely to petroleum.
Q 16What nickname do drillers give the stack of valves and fittings fixed atop a completed well?
Christmas tree
Christmas tree is the trade name for the valves, spools and fittings that control flow from a finished well; such devices became commonplace after one tamed the runaway Spindletop gusher in 1901.
Q 17Which refining process, patented by Vladimir Shukhov in 1891, turns heavy oil fractions into petrol?
Cracking
Cracking uses heat, pressure and often a catalyst to break long hydrocarbon chains into the shorter molecules petrol needs. In 1924 Sinclair Oil sent a delegation to Shukhov to confirm that Burton's American process matched his patents.
Q 18Crude oil is called 'sour' rather than 'sweet' when it is rich in which element?
Sulfur
Sulfur makes a crude sour, while low-sulfur oil is sweet; the label is said to come from early prospectors who tasted and smelled samples to judge their quality.
Q 19Thomas Newcomen's 1712 atmospheric engine, the first practical steam-powered machine, did what job?
Pump water from mines
Pump water from mines is what Newcomen engines did across Europe, keeping flooded coal and metal workings dry. It was the first practical device to harness steam to produce mechanical work.
Q 20Which ancient people piped seeping natural gas through bamboo pipelines to boil brine for salt?
The Chinese
The Chinese ran gas from surface seeps along crude bamboo pipes to salt works in Sichuan's Ziliujing district, where it boiled brine dry. The salt, not the gas, was the prize.
Iraq's forces torched the wells as a US-led coalition drove them out of Kuwait; the first fires were put out in April 1991, and the last well was not capped until 6 November.
Q 24Deepwater Horizon, the rig that exploded in 2010 while drilling for BP, was owned by which contractor?
Transocean
Transocean owned the semi-submersible rig and leased it to BP; the blowout at the Macondo prospect on 20 April 2010 killed 11 workers and lit a fireball visible from 40 miles away. Hyundai had built it in South Korea in 2001.
Q 25Which 1890 law did the Supreme Court use to break up Standard Oil?
Sherman Antitrust Act
The Sherman Antitrust Act was the weapon: in 1911 the court found Standard Oil an illegal monopoly and split it into dozens of companies, the ancestors of ExxonMobil and Chevron.
Q 26Whose exposé 'The History of the Standard Oil Company' helped bring the government's antitrust charge?
Ida Tarbell
Ida Tarbell's reporting laid out the railroad rebates and preferences the trust had used to crush rivals, and the Justice Department sued in November 1906.
Q 27Which two companies were formed to develop production at Spindletop after its 1901 gusher?
Gulf Oil and Texaco
Gulf Oil and Texaco, both now folded into Chevron, were start-ups born at Spindletop, where the Lucas gusher blew 100,000 barrels a day for nine days. They grew into serious rivals to Standard Oil.
Q 28Why did a backer style Edwin Drake, who struck oil at Titusville in 1859, as 'Colonel'?
To impress the locals
To impress the locals was the whole idea: Drake had no military experience, but his backer Townsend gave him the title anyway. It stuck for life, and Vincent Price played Colonel Drake in a 1954 film.
Q 29Which nation's state-oil boss coined 'Seven Sisters' for the majors after they refused him membership?
Italy
Italy's Enrico Mattei, head of state-owned Eni, was refused a seat among the majors, so he dubbed them the 'Seven Sisters' and offered oil states a 75-25 profit split in place of the usual 50-50.
Q 30Which technique, later the key to shale, was first tried in Kansas in 1947?
Hydraulic fracturing
Hydraulic fracturing was first tried by Stanolind on a well in the Hugoton gas field; the firm patented the process and licensed it to Halliburton, which ran the first commercial jobs in 1949.
