Question
_________is converted to lignite.

Peat
The correct answer is: Peat

_________is not a fossil fuel.
The correct option is c)Thorium.
Fossil fuels are made by decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen that can be burned to produce energy. Coal, oil and natural gas are examples of fossil fuels. Fossil fuels are non-renewable resources and waiting millions of years for new deposits of coal, oil and natural gas to form is not a viable solution.
