Final answer:
Both the United States and Canada have substantial deposits of three fossil fuels: coal, oil, and natural gas. These fossil fuels have played a key role in powering industrialization and urbanization.
Step-by-step explanation:
The three fossil fuels found in both the United States and Canada are coal, oil, and natural gas.
In Canada, there are substantial deposits of these fossil fuels in the province of Alberta. Oil is found in tar sands and can be extracted and refined for fuel. Coal and natural gas are also found in abundance.
In the United States, these three fossil fuels accounted for about 80% of total primary energy production in 2019. They are essential sources of energy that have powered industrialization and urbanization.
