What type of energy produces no greenhouse gases, but leaves behind harmful waste?
Coal
Nuclear
Natural Gas
Petroleum
How are fossil fuels formed?
Plankton decomposes into natural gas and oil, plants become coal after millions of years under the ground
Plants decompose into natural gas and oil, plankton become coal after millions of years under the ground
Deposits of methane are subjected to high pressure until they condense into crystals.
Organic remains get trapped in nonporous rock and merge into large bodies of complex, energyrich carbon molecules.
What are the 3 main types of fossil fuels?
Coal, Natural Gas, and Oil
Natural Gas, Uranium, Oil
Oil, Natural Gas, Solar
Coal, Petroleum, Wind
What is renewable energy?
Sources of energy that will take years to deplete.
Sources of energy that humans can manufacture.
Sources of energy that are constantly being formed.
Sources of energy that were once living organisms.
What is geothermal power?
Energy source that requires the use of a river.
Energy source that relies on the power of the sun.
Energy source that will work anywhere on Earth without causing pollution.
Energy source that produces no greenhouse gas emissions or harm to human health, but is only available in certain locations
What is an advantage of nuclear energy?
It is the safest form of energy.
There are no hazardous wastes.
It is a renewable resource.
It does not produce air pollution.
What is the main problem with solar energy?
Solar panels are very expensive and large areas are needed to put them.
Replacement parts are hard to find and systems are difficult to install.
Solar panels will collect more energy than can be stored, causing a system overload.
Solar energy will cause cancer in organisms living near the panels.
What are two examples of renewable energy?
Geothermal and Wind
Solar and Coal
Wind and Natural Gas
Geothermal and Nuclear
What is nuclear fission?
The splitting of an atom's nucleus into two smaller nuclei.
The fusing of two smaller nuclei into one heavier nucleus.
What element is primarily used in nuclear fission?
Uranium
Carbon
Manganese
Lead
How is coal formed?
sediments cover dead marine organisms and heat converts them into complex, energy-rich carbon molecules.
deposits of methane are subjected to high pressure until they condense into crystals.
swamplands are buried by sediment. The added weight creates heat and pressure that converts the plants to coal.
organic remains get trapped in nonporous rock and merge into large bodies of complex, energy rich carbon molecules.
What is the dirtiest type of fuel that creates lots of pollution?
Coal
Nuclear
Solar
Petroleum
Why would a fossil fuel be considered non-renewable?
It cannot be replaced as fast as people use it.
It can be recycled.
It can easily be replaced as it is used.
It is available in unlimited supplies.
How is petroleum formed?
The migration of inorganic molecules to nonporous formations.
The burning of high sulfur, low-grade uranium.
The decay of tiny marine organisms that accumulated on the ocean floor millions of years ago.
The decay of plants that lived in swamps hundreds of thousands of years ago.
How does the use of fossil fuels affect the atmosphere?
Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere.
Burning fossil fuels helps heal the ozone layer.
Burning fossil fuels adds a protective layer around the Earth.
Burning fossil fuels clears the atmosphere of carcinogens.
Which of the following is a major source of biomass fuel in developing countries?
Dung and Wood
Dung and Corn
Corn and Wood
What process is demonstrated by the image?
