Question

what is a fossil fuel explain in positive and negative effect​

Answer 1

A natural fuel such as coal or oil, that was formed millions of years ago from dead animals or plants in the ground is called fossil fuel .

Negative: Global Warming. The major downside to the use of fossil fuels is, of course, the pollution that they cause. The burning of these fuels releases carbon dioxide, a harmful gas that when released into the atmosphere causes a greenhouse effect.
Positive: Convenience

Fossil fuels have the capacity to generate large amounts of energy and this is the main reason why they are so popular. They are highly combustible, yet stable in comparison to a lot of other fuels. Fossil fuels are easy to locate and transport. Also, since they have been in use for a considerably long amount of time, industries are already familiar with the processes required to extract and refine these fuels, so the production time to make these energy sources available for use is significantly lower than alternative sources of energy that may require more time and effort spent.
