What is the main reason why fewer nuclear power plants are being built today?
Nuclear fusion plants are being built instead
Federal laws were passed prohibiting new plants
They have become too expensive
Supplies of U235 are exhausted
Electric generators work by
converting oil into electricity
turning turbines in a dam
converting mechanical energy into electrical energy
rubbing copper against materials that do not conduct electricity
Oil and Natural gas result from
the migration of complex carbohydrates to nonporous rock formations
the decay of tiny marine organisms that accumulated on the ocean floor millions of years ago
the burning of high sulfur, low grade uranium
the decay of plants that lived in swamps hundreds of thousands of years ago
New nuclei and neutrons result from
nuclear fusion
the release of electrons from a positively charged atom
the splitting of an atom's nucleus
the splitting of an atom's neutron
Nuclear fusion
must take place at extremely high temperatures
does not release a great amount of energy
must take place in low density containers
results in nuclei that are lighter in weight
Storage sites for nuclear waste
can only be located in mountain ranges
will always leak lethal amounts of radiation
should only be located in areas that are geologically stable
should be able to undergo transmutation
Solar energy is contained in
uranium
radioactive waste
fossil fuels
all nonrenewable resources
a fuel's suitability is dependent on all of the following factors except
energy content
cost
availability
magnetism
How is electricity generated in a coal powered plant?
heat from the burning coal boils water and produces steam which turns the turbines
heat from the burning coal heats the air which turns the turbines
the turbine breaks down the coal into liquid fuel that powers the generator
the coal is heated until it vaporizes and the vapor is the distilled in the combustion chamber which turns the turbine
Coal is formed when
sediments cover dead marine organisms
deposits of methane are subjected to high pressure
swamplands are buried by sediment and they weight provides heat & pressure that converts plants to coal
organic remains get trapped in nonporous rocks and merge into high energy molecules
Which of the following is an advantage of nuclear energy
It does not produce solid waste
It is cost efficient
It poses no safety risks
It does not produce air pollution
Which of the following is not a main use of fuel
transportation
manufacturing
heating and cooling
cooking
The energy in fossil fuels is converted into
electricity
magnetic fields
uranium
power plants
Much of the oil and gas in the United States is located in
Alaska, Minnesota, New York, Texas
Alaska, California, Michigan, Nevada
Texas, Colorado, New York, Gulf of Mexico
Alaska, Texas, California, Gulf of Mexico
Residents of ______ & _______ enjoy some of the lowest gas taxes in the world.
Russia, Venezuela
United States, Canada
Mexico, United States
England, Italy
Oil and Natural Gas result from the decay of_____ that accumulated on the ________floor millions of years ago.
plants, forest
marine animals, ocean
rats, kitchen
catfish, lake
A major source of pollution when coal is burned is _______
oxygen
nitrogen
sulfur
uranium
Oil is found in and around major geologic features, such as ______, _______, and _________, that tend to trap oil as it moves in the earth's crust.
volcanoes
faults
salt domes
folds
The forces that hold together the _____ of an atom are more than ________ times stronger than the chemical bonds between atoms.
electrons, a hundred
protons, a million
nucleus, a million
neutrons, a billion
When operated properly, nuclear plants release less _______ than coal powered plants do.
radioactivity
electricity
nuclear waste
oxygen
