Impact on the Carbon Cycle
• List as many ways that human
activity may disrupt the Carbon Cycle
• Use your cycle diagram to help you
• Discuss
What are fossil fuels?
• Fossil fuels are hydrocarbons, primarily
coal, petroleum, fuel oil and gas.
• They formed from the fossilised remains
of dead plants and animals by exposure
to heat and pressure in the Earth's crust
over hundreds of millions of years
What’s the problem?
• The burning of fossil fuels by humans is
the largest source of emissions of
carbon dioxide, which is one of the
greenhouse gases that contributes to
global warming.
• This means that the surface temperature
of the Earth will rise in response.
Fossil Fuels
What can we do?
List at least 5
Indicator species:
• Looking at Lichens
Lichens are the crusty organisms that grow in
places such as on rocks and bricks.
• You can also find them on gravestones and the
side of trees.
• They range in colour from grey-green to orange
and red.
Lichens
• Sulphur dioxide gas is produced when fuels like coal and oil are
burned.
• Some lichens are very sensitive to air pollution
• In areas of low air pollution:
-a large variety of different lichen species
-lichens tend to be big and fluffy
• In areas of high air pollution:
-very limited variety of lichen species
-lichens tend to be small and crusty
We can use lichens as an indicator species.
Explain what you think an indicator species is!
