Fossil Fuels:

eg - coal, oil and natural gas

* when burned it produces heat energy

* remained millions of years ago

* disadvantages - non-renewable

- limited access

- releases Co2 = greenhouse effect and increases global warming

- coal and oil = releases sulphur dioxide when burned causing acid rain.

Nuclear Fuels

* uranium and plutonium

* radioactive metals

* disadvantages - non-renewable

- remains radioactive for thousands of years

* Atom = nucleus and the number of protons and neutrons surrounded by electrons


radioactive isotope - time taken for half its radioactive atoms to decay
