☞ What are Fossil Fuels?

• Fossil fuels are buried flammable geologic deposits of organic substances such as dead plants, and animals that got deposited under several thousand feet of silt.
• These deposits decayed with the passage of time and got converted to natural gas, coal, and petroleum due to the extreme heat and pressure inside the earth’s crust.
• They are also known as non-renewable sources of energy as it takes a very long time for it to replenish.
