Because it takes millions of years of high temperature and pressure to turn vegetation and animal matter into fossil fuels (coal, oil and natural gas).
A second reason is, they emit too much greenhouse gases.
Fossil fuels.
No, not all fossil fuels are liquids. Fossil fuels can exist in three states: solids (coal), liquids (petroleum/oil), and gases (natural gas). This variety of states allows for different uses and applications across industries.
Humans have been using fossil fuels for around 200 years, starting in the early 19th century with the Industrial Revolution. The widespread use of fossil fuels such as coal, oil, and natural gas has significantly shaped modern society and economies.
Burning fossil fuels such as coal or natural gas can increase the carbon dioxide in the atmosphere.
Fossil fuels are mainly composed of carbon and hydrogen. These elements make up the hydrocarbons found in fossil fuels like coal, oil, and natural gas.
If Earth did then there wouldn't be electricity, coal or anything that we humans rely on today that uses fossil fuels.
Fossil fuels.
Fossil Fuels
Crude oil, gas, coal are three examples of fossil fuels. Once used, they can't be replaced by humans.
Fossil fuels are: coal methane, petroleum.
Coal IS a fossil fuel
fossil fuels does have coal in it because when the smoke comes up, coal in already in it!!! I am not 100% sure this is right.............
Because coal and petroleum are themselves fossil fuels.
Coal is a fossil fuel. The major fossil fuels are natural gas, crude oil and coal.
The major fossil fuels are coal, oil, and natural gas.
Fossil fuels include the Natural gases, the Petrol, the Coal.
Crude oil and coal are two examples of fossil fuels.
