Fossil Fuels + Geothermal Energy

Question 1

Energy Resource

Answer 1

is used to generate electricity and other useful forms of energy

Question 2

Fossil Fuels

Answer 2

• (such as coal and oil) are burned to heat a fluid (water)
• which creates steam and turns a turbine
• the turbine rotates, which turns a generator

Question 3

Advantage of using Fossil Fuels (1)

Answer 3

reliable

Question 4

Disadvantages of using Fossil Fuels (3)

Answer 4

• non-renewable
• inefficient
• contributes to global warming

Question 5

Geothermal Energy

Answer 5

• in volcanic places, magma (underground lava) has lots of internal energy
• the magma heats rocks, which heat water in pipes
• this rotates a turbine, which turns a generator

Question 6

Advantages of using Geothermal Energy (3)

Answer 6

• renewable
• reliable
• does not produce greenhouse gases

Question 7

Disadvantages of using Geothermal Energy (2)

Answer 7

• can only be used where there is volcanic activity close to the surface
• geothermal plants can lead to the instability of the land surrounding it

Question 8

Answer 8

• Geothermal
• Solar
• Nuclear
• Tidal
• Fossil Fuels
• Wind
• Water/hydroelectric
