Answer 1

• oil
• gas
• coal

Question 2

what are ‘Fossil fuels’

Answer 2

• Fossil fuels are formed from the remains of dead plants and animals.

• The supply of fossil fuels is limited and as demand is increasing we will eventually run out.

Question 4

advantages of fossil fuel

Answer 4

• A small amount of fuel creates large amounts of energy.

- Fuel is very safe and stable to transport and use.

Question 5

how does ‘Nuclear power work’

Answer 5

• A high energy source of heat is created.
• This heats water into steam.
• The steam drives a turbine.
• The turbine then generates electricity.

Question 6

advantages of ‘Nuclear power’

Answer 6

• The process is clean and efficient.
• Power plants don’t need a lot of space.
• It is a reliable source of energy

Question 7

the disadvantage of ‘Nuclear power’

Answer 7

• The waste that the process creates is radioactive.
  (This creates serious damage to the environment and life forms if there is a leak).
• If there is a problem in the plant or station and the reactor explodes the effect is disastrous.
