1 Earth Science Chapter 5 Energy Resources Class Notes: Copy everything.
2 Nonrenewable resources may take thousands or MILLIONS of years! Ch.5 Section 1 SummaryRenewableresources can be replacedwithin a relatively shortperiod of time.Nonrenewable resources may take thousands or MILLIONS of years!
3 Ch. 5 Section 2 SummaryPetroleum is a liquid fossil fuel that is made of hydrocarbon compounds.Natural gas is a gaseous fossil fuel that forms from the remains of swamp plants.
4 Ch. 5 Section 2 Summary Continued Fossil fuels are obtained by drilling oil wells, mining below Earths surface, and strip mining.America imports half of the petroleum it uses from the Middle East, South America, Africa, Mexico, and Canada.
5 Ch. 5 Sec. 3 Summary For Fusion to take place, high temperatures are necessary.Fuel cells combine hydrogen and oxygen to produce electrical energy.Fuel cells release WATER as a byproduct.
6 QuestionWhat is the difference between fusion and fission? Write the answer in your notes.Energy released by fission or fusion reactions is NUCLEAR ENERGY.
7 Ch. 5 Section 3 SummaryWind power is a renewable resource that doesn’t emit pollution.Solar energy is arenewable resource that doesn’t emit pollution, but solar panels are expensive.
8 ContinuedGeothermal Energy comes from Earth, but its only available in certain areas.
