Question

you have just learned about alternative energy sources. now match each term with its definition.

aerogenerator
geothermal energy
nuclear fusion
nuclear fission

a windmill used to generate electricity; also called a wind turbine generator
heat energy that is generated deep within earth
the source of the energy given off by the sun, this process occurs when two atomic nuclei fuse to become one larger nucleus
a reaction in which the nucleus of a large atom is split into smaller nuclei, emitting large amounts of energy

Explanation:

Each term is matched to its standard scientific definition:

• Aerogenerators are wind-based electricity generators.
• Geothermal energy uses Earth's internal heat.
• Nuclear fusion is the sun's energy-producing process of fusing small nuclei.
• Nuclear fission splits large atomic nuclei to release energy.

Answer:

1. aerogenerator → a windmill used to generate electricity; also called a wind turbine generator
2. geothermal energy → heat energy that is generated deep within Earth
3. nuclear fusion → the source of the energy given off by the sun, this process occurs when two atomic nuclei fuse to become one larger nucleus
4. nuclear fission → a reaction in which the nucleus of a large atom is split into smaller nuclei, emitting large amounts of energy
