If your worksheet includes a matching section for renewable sources, use these common pairings:

Kinetic energy of wind converted into electricity via wind turbines. To truly excel, take the next step: apply

A3: They form from the remains of ancient plants and animals over millions of years, so their formation rate is far slower than the rate at which humans use them.

The answer key gets you points on a test, but understanding energy resources prepares you for life on a planet with finite resources and a changing climate.

| Term | Match with Definition | |------|----------------------| | Fossil fuel | C. Formed from ancient organisms | | Nonrenewable | E. Fixed amount, cannot be replaced quickly | | Renewable | A. Replenished naturally in short time | | Nuclear fission | D. Splitting atomic nuclei | | Hydroelectric | B. Energy from flowing water | | Geothermal | F. Heat from Earth’s interior | Discuss nuclear energy’s role in a low-carbon future

Kinetic energy from wind turning giant blades to generate electricity.

Geothermal power taps into the Earth's internal heat. Wells are drilled into underground reservoirs of hot water or steam, which then drive turbines.

: While not a fossil fuel, uranium is a nonrenewable mineral mined from the Earth. It provides steady power through nuclear fission but presents challenges like radioactive waste disposal. 2. Renewable Energy Resources
