Question 18

most of the earths energy comes from

Answer 18

the sun

Question 19

transforms the energy in an energy source into electric energy

Answer 19

electric power plants

Question 20

an energy resource that is available in limited amounts or that is used faster than it is replaced in nature

Answer 20

nonrenewable energy resource

Question 21

the remains of ancient organisms that can be burned as an energy source. (coal, natural gas, petroleum.)

Answer 21

fossil fuels

Question 22

fossil fuels form from…

Answer 22

Microscopic organisms are buried deep in earth’s layers, forming fossil fuels over millions of years

Question 23

Electric power plants burn __% of the coal used in the US

Answer 23

93

Question 24

Electric power plants burn about __% of the natural gas used in the US

Answer 24

32

Question 25

Negative consequences of fossil fuels

Answer 25

Burning fossil fuels creates carbon dioxide, warming our atmosphere and creating global warming

Question 26

Nuclear power plants…

Answer 26

DO NOT release pollutants into the air, but instead it produces harmful nuclear waste

Question 27

Nuclear power plants store…

Answer 27

the radioactive waste that can harm living things

Question 28

an energy resource that is replaced as fast as, or faster than, it is used

Answer 28

renewable energy resource

Question 29

Hydroelectric power plants

Answer 29

Dams create a path of flowing water that spins a turbine, forming kinetic energy that can be transformed into usable energy

Question 30

Solar panels

Answer 30

collect solar energy as a clean energy resource from the sun.

Question 31

an energy resource that cannot be used up

Answer 31

Inexhaustible energy resource

Question 32

Wind energy

Answer 32

Windmills collect energy from the wind, but it’s not practical because wind cannot be determined

Question 33

Biomass energy

Answer 33

Burning woods are a renewable resource because its a plant based material. (animal based also works)

Answer 35

90

Question 36

conserving energy

Answer 36

saving and using less energy so we have some for the future.
