How are fossil fuels made into heat?
Fossil fuels (coal, oil and natural gas) are burned. The heat from the burning is used directly, or is used to produce electricity, which can then be used to generate heat.
They don't have to be. Some fuels are fossil fuels, which are rapidly disappearing right now. Some examples of fossil fuels are oil, which we use for gas, and coal, which we use for heat and electricity. But fossil fuels take millions of years to make more, so we are rapidly using up the fossil fuels of the world.
Fossil Fuels are basically the three main things: Coal, Oil, and Natural gas. When these fossil fuels are burned they create pollution and add to the Greenhouse effect. Fossil fuels are also known as Greenhouse gases. The Greenhouse effect is caused by fossil fuels and what happens is basically heat is trapped in our Earths atmosphere causing global warming.
