The coal field location related to coal fields in the United States and supporting the theory of continental drift is Europe.
1. Europe's coal fields are connected to those in the United States, indicating a shared geological history.
2. The theory of continental drift suggests that continents were once joined together in a supercontinent called Pangaea and have since drifted apart.
3. Coal deposits in Europe and the United States that align geologically and show similar patterns support the theory of continental drift.
4. Therefore, Europe is the coal field location that is related to coal fields in the United States and supports the theory of continental drift.
