Question

why are fossil fuels classified as non renewable source of energy

Answer 1

Fossil fuels are present in fixed or limited amount and can be exhausted by human activities and also can't be renewed fast enough therefore they are considered as Non Renewable Resources .

Answer 2

Fossil fuels are classified as non-renewable resources because:

• Fossil fuels are naturally occurring materials containing hydrocarbons that are found within the earth's crust.
• It is the decomposed remains of plants and animals.
• But this decomposition takes millions of years.
• When the dead plants and animals get buried deep inside the earth, it gets exposed to very high temperature and pressure.
• They slowly break down and get transformed into materials with large amounts of energy stored in them.
• These are the fossil fuels that are extracted from the earth's crust and used by humans.
• Since this whole conversion process takes millions of years and the rate at which humans consume them is very high (uses them up in a few years), fossil fuels are classified as non-renewable resources.
