Los combustibles fósiles: formación

Fossil fuels, providing 90% of the world's energy, are hydrocarbons formed from prehistoric organisms. Plants convert solar energy via photosynthesis, and when they die, microorganisms decompose them. Over time, pressure and heat transform this organic matter into fossil fuels. Oil and gas originate from marine organisms, while charcoal comes from terrestrial vegetation. These fuels are finite and unsustainable due to their long formation period.

What are fossil fuels primarily composed of?

• Proteins

• Carbohydrates

• Nucleic acids

• Hydrocarbons

How do plants contribute to the formation of fossil fuels?

• By providing oxygen for combustion

• By turning into coal directly

• By absorbing sunlight and storing energy

• By decomposing into oil

What conditions are necessary for the transformation of organic matter into fossil fuels?

• Constant moisture

• High pressure and heat

• Low temperature and pressure

• Direct sunlight

Which type of fossil fuel is typically formed from marine organisms?

• Charcoal

• Natural gas

• Peat

• Coal

Why is the reliance on fossil fuels considered unsustainable?

• They are finite and take millions of years to form

• They form quickly

• They are abundant

• They are renewable
