What are differences between natural gas, coal, and oil ...

All may be considered "fossil fuels", but they differ in time and conditions of formation and chemical composition. Coal is a solid, oil is a liquid and natural gas is a vapor (gas). Coal and oil form from deposits of animal and vegetable matter deep in the ground at conditions of high pressure over many years. Natural gas is also formed during those processes, but it can also be generated ...
