1- Reliance On Fossil Fuels Flashcards
Name the 3 fossil fuels used on earth
Coal, crude oil and natural gas
Define the term ‘fossil fuel’
A fuel consisting of organisms preserved in rocks in the earth’s crust with high carbon and hydrogen content
Define the term ‘renewable energy source’
A form of energy derived from natural sources that do not use up natural resources to harm the environment
List 3 examples of biomass
Wood, grass and vegetation/ other legible examples
Give 3 problems associated with the use of fossil fuels
- Non renewable
- Expensive to harvest
- Combustion of fossil fuels harms ozone layer
List 4 uses of fossil fuels in modern day life
-Plastics- crude oil used to form plastics for packaging etc.
-Pharmaceutics- fractions of crude oil used to produce medicines e.g aspirin or penicillin.
-Transport- engines in vehicles use internal combustion of petrol and diesel from crude oil.
-Fibres- nylon and acrylic formed from crude oil.
Suggest 3 ways human reliance on plastic can be reduced.
- government bans on single use plastics
- supermarkets charging for plastic bags
- recycling
Why is global action required to tackle fossil fuel depletion
Fossil fuels take hundreds of millions of years to form. The rate of usage has rapidly increased since the I.R. The supply is finite and may simply run out.
Describe the trend of fossil fuel usage since Industrial Revolution.
Rapid increase.
Why is the estimation of the fossil fuel lasting projection not fully accurate?
New crude oil fields discovered and technology may or may not be available to access these areas in the coming years.

What is carbon trading?
A method that aims to reduce carbon emissions of a nation, by providing incentives for major polluting industries.
What does IPCC stand for
Intergovernmental Panel on Climate change
State 6 pieces of evidence provided by IPCC proving climate change is caused by humans.
Volatile weather patterns
Sea temperatures risen
Ecological e.g damaging of coral reefs
Polar ice caps melting
Fewer cold days, nights and frost events
Rises in sea levels (75% due to expansion of the water molecules 25% due to polar ice caps melting)
What is another word for human induced ?
Anthropogenic
