Fossil fuels (coal, oil and natural gas) began their lives more than 300 million years ago, before the dinosaurs, when trees and other vegetation became covered with silt and debris. The long years of heat and pressure eventually turned them into hydrocarbons.
They began to be formed millions of years ago
See this site for something more useful than that: http://www.solcomhouse.com/fossilfuels.htm
They were mostly alive in the carboniferous period around 350 to 290 million years ago, a time of great land diversity.
long before the dinosaurs even ruled the world.
400 million years
More than 50 million years.
fossil fuels is the answer correct
When fossil fuels are burned, they release energy stored years ago.
Fossil fuels come from plants and microscopic organisms, which long ago died and were buried in the earth and slowly transformed into coal, oil, and gas. These plants and microorganisms once, millions of years ago, got their energy from the sun. Thus, all fossil fuels received some solar energy.
Fossil fuels, coal, oil and natural gas, are a non-renewable source of energy. Formed from plants and animals that lived up to 300 million years ago, fossil fuels are found in deposits beneath the earth
short answerA bad idea, since(i) they produce CO2 (partly responsible for the rise in global warming),(ii) there is a limited amount of fossil fuel from which we make valuable materials such as lubricants and plastics,(iii) fossil fuel resources are finite, so burning them means we are consuming a resource we can never replace, and(iv) we can actually build new industries and create many new jobs developing renewable sources of energy instead of burning fossil fuels.
It is fossil fuels.
Fossil Fuels:)
fossil fuels is the answer correct
Fossil fuels.
Organic matter was compressed and heated
Fossil fuels are the sources of energy formed millions of years ago under the ground (coal, oil and natural gas).
the fossil fuel created is coal
Fossil Fuels
A long time ago
organic matter
Coal, petroleum,and natural gas, are called fossil fuels because they were formed millions of years ago, during the Carboniferous period.
it will change if we use lots of fossil fuels. Because we cannot make fossil feuls because it is from long time ago. from:Alex
