Fossil Power

-How does it work?

  • Fossil fuel is a source of non-renewable energy.
  • Coal, petroleum, natural gas, these are all considered as fossil fuels.

- Where can you find “plants” of this source?

Fossil power:

Fossil fuels are non-renewable energy sources that formed more than 300 million years ago during the Carboniferous Period. They are made up of plant and animal matter.

My part:

What is the effect on the enviroment of fossil power:

Disatvantages:
  • It produces a lot of Carbon Dioxide, it produces more Carbon Dioxide than burning oil or gas
  • This Carbon Dioxide increases 25% of the global warming
  • When the factories make fossil fuel a certain gas is produced this gas contains: carbon monoxide, nitrogen oxides, sulfur oxides, and hydrocarbons this is also very bad for the enviroment and global warming
  • It can also cause water pollution for example when they spill oil in waterways the whole waterway is affected because the oil has so many stuff in it it will spread very fast
  • There also a lot of air pollution with the gas because of al the gasses in it it produces a lot of smog and this is one of the most important causes of air pollution
* How can we improve this horrible effects? :
  • Well you can not recycle it so that's not an option
  • There is no way to improve it or making more environment friendly

Where can you found fossil power?

  • Fossil fuels is found over time in sand, sedimant and in rock buried these are the organic matter.
  • These materials formed large quantities of fuels.

how does fossil power work
  • coal or oil is burned to produce heat
  • the heat converts water into steam
  • the steam is used to drive a turbine, within the turbine is a wire, surrounded by electromagnets
  • this generates electricity

fossil power

summary
  • burn fuel
  • heat water to make steam
  • steam turns turbines
  • turbines turn generators
  • the generators produce electrical power

fossil power:

where does fossil power come from?

  • Fossil power comes from fossil fuels which are found within the rocks of continents, islands, and below ocean and sea beds all over the earth. It is believed that this non-renewable form of energy was formed millions of years ago from geological processes that acted on dead animals and plants. there are a loads of diffrent types of fossil fuels for example: coal, oil, natral gases, wood, biomass and nuclear.

where are they to be found?

coal

  • They are made up of layers of earth which for example, most of our coal was formed about 300 million years ago, when most of the earth was covered by steamy swamps. As plants and trees died, their remains sank to the bottom of the swampy areas, and after a while layers are formed and eventually forming a soggy, dense material called peat.


natural gases

  • We now know how coal is made but what about oil and natural gas? oil is formed in the sea, as the microscopic plants and animals live in the sea and they absorbed energy from the sun, which was stored as a carbon molecules in their bodies. then they die and fall to the sea bed.
