Question 18

Coal

Answer 18

• formed from plant remains

* must be mined from the ground

Question 19

Oil

Answer 19

• liquid fossil fuel

* formed from small animals, algae, and other organisms that lived in the sea millions of years ago.

Question 20

Natural Gas

Answer 20

• mixture of methane and other gases.

* forms from some of the same organisms as oil.

Question 21

What is renewable resources?

Answer 21

• constantly being supplied

* scientists are looking for ways to use these resources to meet our energy needs.

Question 22

Answer 22

Solar Energy
Hydroelectric power
Wind power
Biomass fuels 
Geothermal energy
Hydrogen power

Question 23

What is the last energy source?

Answer 23

Nuclear energy

Question 24

Fossil fuels are something that we...

Answer 24

Pump or dig up.

Question 25

When energy is stored it is called...

Answer 25

Potential energy

Question 26

When energy is moving we call it...

Answer 26

Kinetic energy

Question 27

Solar energy

Answer 27

* comes from the sun * is the source either directly or indirectly of most renewable energy sources. * earth receives enough solar energy each day to power the earth for 40 years.

Question 28

Hydroelectric power:

Answer 28

* power produced by flowing water. * a dam built across a river blocks the flow of water and creates a reservoir. * when the dam control gates open, water flows through tunnels turning turbines that are connected to generators. * generators create electricity.

Question 29

Wind power:

Answer 29

* wind can be used to turn a turbine and generate electricity. * wind is a major source of power in places where it is difficult to transport fuel.

Question 30

Biomass fuels:

Answer 30

• made from living things ~ Ex: wood, leaves, food waste, manure. • alcohol can be added to gasoline, methane created by bacteria can heat buildings, etc.

Question 31

Geothermal energy:

Answer 31

• water is heated by magma( melted rock) under earths surface.

Question 32

Hydrogen power:

Answer 32

• pure hydrogen burns cleanly, creates no smog or acid rain, and exists on earth in large supply.

Question 33

Nuclear power:

Answer 33

* comes from splitting the the nucleus of atoms. * about 20% of the US and more than 70% of France's energy comes from nuclear power. * the heat released by splitting atoms is used to change water into steam. This steam turns turns a turbine to generate electricity.

Question 34

What is solar energy's problem?

Answer 34

* figuring out how to store and use this power.

Question 35

What is hydroelectric energy's problem?

Answer 35

* most rivers have already been dammed and dams can have a negative affect on the environment.

Question 36

What is wind power's problem?

Answer 36

* few places have steady winds.

Question 37

What is Biomass fuels problem?

Answer 37

* takes time to regrow trees that have been cut down and producing alcohol and methane in large quantities is expensive.

Question 38

What is Geothermal energy's problem?

Answer 38

* only a few places have magma close enough to earths surface. Deep drilling is expensive.

Question 39

What is Hydrogen powers problem?

Answer 39

* mostly combined with oxygen in water on earth. It takes more energy to obtain the hydrogen than is produced by burning it.

Question 40

Two ways to preserve our current energy resources.

Answer 40

1) increase the efficiency of our energy use. | 2) reduce energy use.

Question 41

What is left over energy usually lost as?

Answer 41

Heat

Question 42

What is efficiency?

Answer 42

The percentage of energy actually used.

Question 43

How to increase efficiency?

Answer 43

1) insulation to trap heat loss. 2) better light bulbs 3) better car tires and engines 4) refuse the number of cars on the road.

Question 44

How to reduce energy use?
