Natural Gas Fossil Fuel Trivia Quiz Questions
What is natural gas?
A: Natural gas (also called fossil gas) is a naturally occurring hydrocarbon
gas mixture consisting primarily of methane.
Natural gas commonly includes varying amounts of other
higher alkanes, and sometimes a small percentage of carbon dioxide,
nitrogen, hydrogen sulfide, or
How is it formed?
A: It is formed when layers of decomposing plant and
animal matter are
exposed to intense heat and pressure under the surface of the Earth over
millions of years.
Natural gas is a non-renewable hydrocarbon used as a
source of energy for what?
A: Heating, cooking, and electricity generation.
It is also used as a fuel for vehicles and as a
chemical feedstock in the manufacture of what?
A: Plastics and other commercially important organic chemicals.
Natural gas has a complicated effect on
it itself is a what?
A: A greenhouse gas, and it releases carbon dioxide when burned.
However natural gas use often supplants
coal use, which
is far more environmentally damaging, leading to what?
A: Lower net carbon dioxide emissions.
Where is natural gas is found?
A: In deep underground rock formations or associated with other hydrocarbon
reservoirs in coal beds and as methane clathrates.
Most natural gas was created over time by what two
A: Biogenic and thermogenic.
Biogenic gas is created by methanogenic organisms in
A: Marshes, bogs, landfills, and shallow sediments.
Deeper in the earth, at greater temperature and
pressure, thermogenic gas is created from what?
A: Buried organic material.
In petroleum production, gas is sometimes burned as
A: Flare gas.
Before natural gas can be used as a fuel, most, but not
all, must be processed to do what?
A: To remove impurities, including water, to meet the specifications of
marketable natural gas.
Natural gas is sometimes informally referred to simply
as "gas", especially when compared to other energy sources such as what?
A: Oil or coal.
However, it is not to be confused with what?
A: Gasoline, especially in North America, where the term gasoline is often
shortened in colloquial usage to gas.
Natural gas was discovered accidentally in ancient
China, as it resulted from what?
A: The drilling for brines.
When was natural gas first used by the Chinese?
A: In about 500 BCE (possibly even 1000 BCE).
They discovered a way to transport gas seeping from the
ground in crude pipelines of bamboo to where it was used to do what?
A: Boil saltwater to extract the
salt, in the Ziliujing District of Sichuan.
When did the discovery and identification of natural
gas in the Americas happen?
A: In 1626.
In 1821, where did William Hart successfully dig the
first natural gas well?
A: At Fredonia, New York, United States.
This led to the formation of the what?
A: The Fredonia Gas Light Company.
In 1836 the city of Philadelphia created the first
A: Municipally owned natural gas distribution venture.
In the 19th century, natural gas was usually obtained
as a by-product of what?
A: Producing oil.
Where was unwanted natural gas a disposal problem?
A: In the active oil fields.
If there was not a market for natural gas near the
wellhead it was prohibitively expensive to do what?
A: To pipe it to the end user.
In the 19th century and early 20th century, unwanted
gas was usually what?
A: Burned off at oil fields.
Today, unwanted gas (or stranded gas without a market)
associated with oil extraction is often what?
A: Returned to the reservoir with 'injection' wells.
In regions with a high natural gas demand (such as the
US), pipelines are constructed when it is what?
A: Economically feasible to transport gas from a wellsite to an end
In addition to transporting gas via pipelines for use
in power generation, other end uses for natural gas include what?
A: Export as liquefied natural gas (LNG) or conversion of natural gas into
other liquid products via gas to liquids (GTL) technologies.
GTL technologies can convert natural gas into liquids
products such as what?
A: Gasoline, diesel or jet fuel.
Natural gas extracted from oil wells is called what?
A: Casinghead gas.
The natural gas industry is extracting an increasing
quantity of gas from what?
A: From challenging resource types: sour gas, tight gas, shale gas, and
There is some disagreement on which country has the
A: Proven gas reserves.
Where is the world's largest gas field?
A: The offshore South Pars / North Dome Gas-Condensate field, shared between
Iran and Qatar.
What is shale gas?
A: Shale gas is natural gas produced from shale.
Because shale has matrix permeability too low to allow
gas to flow in economical quantities, shale gas wells depend on what to
allow the gas to flow?
Early shale gas wells depended on natural fractures
through which gas flowed; almost all shale gas wells today require what?
A: Fractures artificially created by hydraulic fracturing.
Since 2000 where has shale gas become a major source of
A: In the United States and Canada.
Because of increased shale gas production, the United
States is now what?
A: The number one natural gas producer in the world.
Following the increased production in the United
States, shale gas exploration is beginning where?
A: In countries such as Poland, China, and South Africa.
What is town gas?
A: Town gas is a flammable gaseous fuel made by the destructive distillation
Because of its low density, it is not easy to store
natural gas or to what?
A: Transport it by vehicle.
Why are natural gas pipelines impractical across
A: The gas needs to be cooled down and compressed, as the friction in the
pipeline causes the gas to heat up.
Many existing pipelines in America are close to
reaching their capacity, prompting some politicians representing northern
states to speak of what?
A: Potential shortages.
