* Slide 1
* -Fossil fuels are hydrocarbons such as coal, fuel oil or natural gas, formed from the remains of dead plants and animals 300million years ago.
* It takes millions of years for the force of pressure within the Earth's crust to convert the fossils into oil, natural gas and coal.
Slide 2-They are used to
* fuel cars and aeroplanes
* heat houses
* create electricity
* Slide 3-These resources are non-renewable, and the supplies are running out at a rapid rate as they are being consumed by the Earth's population.
These substances are being used much faster than they are being produced and if we keep going the way we are they will be run out by 2052.
Slide4 – a bad effect of burning fossil fuels is global warming. Fossil fuels emit carbon dioxide and other greenhouse gases, which contribute to global warming. This may lead to drastic climatic changes and as a result affects the ecosystem as a whole
The combustion of fossil fuels is considered to be the largest contributing factor to atmospheric pollution. Burning coal is a leading cause of air pollution and greenhouse gases. Use of fuel oil also results in the emission of large amounts of toxins in urban areas. Air pollution can lead to the formation of smog, which not only affects human health but also affects the growth of crops.
The most visible source of petroleum pollution is oil-tanker spills, which poses a threat to the marine lifeand Fossil fuel-based fertilizers also contribute to water pollutiontherefore, coal mining causes water pollution during transportation and processing.
