Trivia: What is NOT a type of fossil fuel?
Coal
Natural gas
Oil
Nuclear
Correct Answer: Nuclear
So why is this answer correct? : Fossil fuels are made from decomposing organic matter that has turned into carbon compounds found in the Earth’s crust, such as plants and animals. Most of the total energy used in the U.S. comes from these fuels. Because new deposits take millions of years to form, fossil fuels are considered nonrenewable resources. Scientists are researching alternative power sources, including renewable sources like geothermal energy and wind power.
