Fuel

Hydrocarbons
(fossil fuels) compounds made up of carbon and hydrogen only
How were fossil fuels formed?
formed from the remains of organisms that lived millions of years ago
coal came from…
ferns and trees
oil and natural gas came from…
animals and plants that lived in the sea
Fossil fuels are burned to produce…
heat energy
Fossil fuels are finite, i.e. they’re…
non-renewable
The enhanced greenhouse effect
- Heat from the sun is trapped by carbon dioxide which causes temperatures to rise
- carbon dioxide levels are increasing due to the burning of fossil fuels
- problems: ice caps melt - increased flooding of land
Biofuels
made by plants e.g. rapeseed oil, they’re renewable and they are also a cleaner fuel for the environment
