it takes million years to form
it is very much expensive
it can be regenerated again
Fossil fuels are formed million years ago from different materials. Which of the following is not its component?
remains of animals
remains of volcanic ashes
remains of bacteria
remains of all vegetation
Coal is one of the major types of fossil fuels. In which types of organic matter does coal come from?
mostly algae
marine organisms
dissolve minerals from rocks
forest trees, plants and marshes
Which of the following is the first event in fossil fuel formation?
They are then able to turn it into products we can use, such as petrol and diesel.
Millions of years ago, the remains of prehistoric plants and animals were buried at the bottom of the Earth
The plants and animals remains were altered chemically by this process and slowly changed into crude oil and natural gas.
The mud sediment was buried by more sediments, and it started to change into rock as the temperature and pressure increased.
