Fossil fuels come from decayed plants and animals. Oil typically comes from dead marine life. Coal comes from decaying plants. So, before they are transformed into fuels (which can take millions of years), the decaying organic material is likely to be brown. Of course, before they die, the plants and animal look just like they do today.
The rock that forms is called a fossil.
The pressure is high and the temperature is also very high
Yes, although the fossil record for the precambrian period is scarce. See related link.
Fossils are the remains of plants and animals that have been turned to stone.
Solar energy (heat and light from the sun) grew the plants which fed the animals. The dead plants and animals, under immense pressure and heat, gradually turned into coal, oil and natural gas, the fossil fuels. When the fuel is burnt, that energy is released.
Most animals that became fossil fuels (coal, oil and natural gas) were tiny plankton in the oceans. Coal was made from larger vegetation and possibly animals like archosaurs, the reptile ancestors of the dinosaurs.
fossil fuels r like decayed plants and animals (so FOSSILS) from 100 million years ago. they get turned into coal and oil and then drilled out.
Fossil fuels (coal, oil and natural gas) are formed from the remains of plants and animals. Three hundred million years' of pressure turned the organic matter into fuel.
Dead plants turned into oil :) hope this helped.
Petrification =D
Because sunlight allowed plants to grow, which made it possible for animals to eat the plants. Eventually the plants got turned into fossil fuels. Apart from geothermal and nuclear energy all energy sources on earth originated with sunlight.
all sea animals that died eventually turned into oil.
