Climate Change Revision Year 8 Flashcards
Name the 4 greenhouse gases
Carbon Dioxide
Methane
Nitrous Oxide
Water Vapour
How is Carbon Dioxide produced?
Animals Breathing
Burning Fossil Fuels
How is Nitrous Oxide produced?
Bacteria in the soil produce it
Fertilisers make them produce more.
How is Methane produced?
This is produced by rotting waste and animal flatulence.
It is also found naturally in pockets underground.
What are the 3 fossil fuels?
Coal, Oil and Methane (natural gas).
How could climate change affect our world?
Rainfall patterns change - some places get more than before, some get less.
Wind patterns change - wind patterns are linked to air pressure, which are linked to temperature. This may cause more storms and produce more powerful storms like hurricanes.
Ice in cold places melts - rising sea levels, some places will be under water, sea temperatures would change.
What are some of the natural causes of climate change?
The amount of energy the Sun gives out can change.
The Earth’s axis can wobble.
The Earth’s path around the Sun can change.
The tilt of the Earth’s axis can change.
Volcanic eruptions.
Meteor collisions with Earth.
Name some things that governments could do to reduce Carbon Dioxide going into the atmosphere.
Use more renewable energy sources to produce electricity.
Ban the use of petrol (gasoline) powered cars.
Stop deforestation.
Invest money in projects to remove Carbon Dioxide from the atmosphere.
Name some things you could do to to reduce the amount of Carbon Dioxide going into the atmosphere.
Walk or cycle instead of using a car.
Turn off lights, Turn down your A/C - reduce how much electricity you use.
Get a solar powered phone charger.
Have solar panels installed on your house.
Reduce the waste you produce re-use and recycle things - the more we consume the more is produced. Production of goods means Carbon Dioxide is produced.
